This includes MBRs of all sizes, origins and ethnicities. It is also to create an industry which is reputable at large, competitive within itself, accessible as well as manageable for all Motor Insurance Companies.The introduction of these standards will create an universal platform for all Motor Insurance companies within South Africa, with no variation between their standards and requirements concerning MBRs. This will help prevent discrimination, uncertainty and unwanted errors in the selection process.Therefore, it was agreed in consensus among delegates from the MBR Associations and the South African Insurance Association (SAIA) to establish this tool which allows to evaluate the MBRs without prejudice. An independent Third Party, (Bureau Veritas), has been appointed to assist in creating and implementing this tool. The delegates of the industry believe that this document outlines a fair and equitable overview of the minimum compliance required to run a professional and well-equipped motor body repair business.PurposeThe main purpose of the platform is that MBRs of all sizes, origins and ethnicity will be given an impartial and identical opportunity, without preconception, to comply with the reasonable grading criteria and become a graded MBR. MBRs will be treated fairly and similarly throughout the complete, transparent and unbiased process thereof.The National Grading Criteria includes basic equipment, standard environment andemployee requirements that have to be fulfilled. Therefore, MBRs that comply with thecriteria will be able to deliver service on an equal quality level giving all MBRs equitable and identical opportunity at receiving work from insurance parties.The quality of the service that certified MBRs deliver will be of good standard, the service will be delivered more time efficiently and effectively, increasing productivity and work load. Efficient and effective service delivery improves customer satisfaction and may increase work opportunities tremendously. Unity will occur on various levels of this industry: •There will be no variation between the standards and requirements of Insurance Industries in South Africa concerning MBRs. 1.Therefore, all MBR’s will feel that they are being treated fairly and the same by all Insurance Parties, creating assurance between the two parties. 2.All insurance industries will therefore have a universal platform to communicate with one another without competitive concerns. •All South African MBRs will be graded according to exactly the same National Grading Criteria, causing unity in the sense that all will be treated fairly in all circumstances. No bias will be experienced and therefore all MBRs will have a sense of equality towards each other. Structure The structure of the National Grading Criteria Check List is as follows: 1.Absolute Minimum Requirements (100% must be obtained for inspection to continue) 2.Minimum Qualification Requirements (100% must be obtained to qualify for certification) o NSR o SRD R A F T3.Optional Information (Additional points) o NSR o SRThree Stages of the National Grading Criteria ListProcessA checklist and manual will be provided by the independent third party to all MBRs to assist and support their preparation to successfully comply with the standards (grading criteria). MBRs have the freedom to take as much time as required to prepare themselves to comply with the National Grading Criteria before they schedule their first audit. It is recommended that MBRs prepare and comply with the criteria as soon as possible so that they may receive certification sooner. By giving the MBRs efficient and effective support, assistance and time, we provide a fair chance to all MBRs to be successful with the National Grading Process. MBRs should use this document to their advantage to increase their chances of a successful audit. It is recommended that MBRs conduct a self-audit according to the manual and grading criteria provided to them by the independent third party. When the MBRs have conducted the self-audit and feel that they have a successful result, only then should they schedule for the first official audit. The audit will be conducted by an accredited independent third party that has been approved by the stated Associations. Please note that audits are conducted on an appointment basis. The audit will take place at the MBRs premises on a prescheduled day which the MBR owner has agreed upon. The audit will be conducted by an independent qualified auditor, who will personally confirm that all requirements are met as per the grading criteria. The MBR associations can appoint interested members as co-auditors who will the join the lead auditor during the audits. With this method, we can guarantee skills transfers. MBRs that comply with the grading criteria will receive a rating and will then be eligible to be added to an insurance panel and a database that is available to all insurance parties. By being listed on this database it serves as confirmation that the MBR will be able to deliver services on an equal quality level which gives all successfully audited MBRs fair and equitable opportunities at receiving work from insurance parties. Absolute Minimum Requirements •NSR & SR - 100% must be obtained •Please note that these are the absolute requirements to qualify Minimum Qualification Requirements •NSR - 100% must be obtained to receive certification •SR - 100% must be obtained to receive certificationOptional Information •NSR - Additional Points •SR - Additional PointsD R A F T Therefore, in order to become a certified member of the Motor Body Repair in South Africa, your business must satisfy the grading criteria as outlined in this document. The National Grading process is as follows:1.Read through the MBR “National Grading Checklist Guide” document.2. Choose whether you are “Structural Repair” or “Non-Structural Repair” or both.3. Use the “National Grading Criteria Check List” to fulfil the requirements and collect all the relevant information as outlined in this document and conduct a self-audit.4. A date will be arranged between the MBR and the accredited independent third party’s auditors for an audit to be done. Audits will take place on an appointment basis only.5. The audit will take place at your MBR premises by an independent auditor .6. When the MBR complies with these criteria, the MBR will be added to the Database for all insurance associations to see and receive a “Confirmed Motor Body Repairer National Grading Certificate”.7. If the MBR does not comply with the criteria at the time of the audit, then a three-month interval will be granted to the MBR to accomplish the unsatisfied requirements before the auditor will either request proof of accomplishment or return for the completion of the audit. 8. MBRs that receive the “Confirmed Motor Body Repairer National Grading Certificate” have the right to publish that they meet the grading criteria .T imeline and StepsMRB accepts the fair and equal opportunity to become a graded MBRAssistance and support is provided by the third party for an unlimited time period MBR uses the provided Manual and Checklist to prepare itself and conduct a self-audit A confirmed audit date will be arranged between MBR and third party (auditor) as soon as MBR is ready The audit will take place at the MBR's premises by an independent auditor If the MBR is non-compliant, a 3 monthinterval will be grantedfor the MBR to satisfyoutstanding requirmentsThe MBR will either send proof of compliance or be re-audited after 3 monthsWhen the MBR complies to all criteria they will receive “Confirmed Motor Body Repairer National Grading Certified MBR will be added to Database and may publish their certified rating Every two years a re-audit must be scheduled by the YESD R A F T DatabaseA database which will list all certified MBRs will be created by the auditing third party. This database will be interfaced on the web page of all Motor Insurers, MBR Associations and SAIA. These Associations will have login details which will give them access to the relevant data of the relevant listed MBRs. This database will be updated on a regular basis by the third party only. The basic structure of the information in the database will be created in consent with the Motor Transformation and Sustainability Forum (MTSF). CertificateAs soon as the MBR complies with all the criteria and is approved by the auditing third party, the MBR will receive its “Confirmed Motor Body Repairer National Grading Certificate” (which will reference whether the MBR has received NSR, SR or Both certification) within two weeks. When the MBR receives its certificate it has the right to publish that it is a certified MBR that meet the industry grading criteria. The certificate entails an unique number and a hologram which protects the industry from fraudulent certificates.V alidityThis certification will commence for a two-year period from the date of the agreement being signed. The agreement will expire after two years from the date of the certification being approved. T o maintain the grading, all participating MBRs will definitely be re-inspected at least every two years to ensure that compliance is maintained. The responsibility ofrenewing the agreement falls solely to the MBR owner , at which point the process mentioned under “Process” must be followed.At any point, the member may apply for a higher (SR) or lower (NSR) category . The MBR Grading process will need to be followed when applying for a different category . When a rightful complaint is received from a client, the “Confirmed Motor Body Repairer National Grading Certificate” may be revoked. When the ownership of a certified MBR changes with more than 50%, the MBR will be re-audited within six months. The certificate will remain valid throughout those six months. Failure of an audit within the six months will result in the certification’s validity to expire. Appeals Process An Appeals Process will be available to all MBRs should they feel that they are being treated unfairly in a judgemental or administrative way. The Appeals process shall work as follows: 1.When an appeal is first filed the MTSF Standards Implementation and Oversight Committee will serve as the mediator between the MBR and the other concerning party involved in this National Grading Process. The Forum Committee is in a good position to judge whether the policies and procedures have been implemented correctly, as they created the processes and grading criteria. 2.The Committee will gather all the facts and bring them to the attention of the parties involved. Therefore, corrective action might be suggested or the MBR might be informed that the decisions or procedures were correct. 3.If a disagreement from one of the parties involved occurs, the appeals process will continue.D RA F T 4.An outside and unbiased arbitrator will make a final and binding resolution. The arbitrator reviews the case, asks questions, interviews witnesses, researches precedents, and so forth.Checklist Manual GuideNumbering SystemEvery criterion question has a number. The alphabet letter before the number refers to the Evaluation Area that the question belongs to.Evaluation AreaAll criteria fall under different evaluation areas of an MBR. An alphabet letter is allocated to each Evaluation Area.Standard Operating Procedures (SOP)All criteria are aligned to National and International standards. An SOP that take these standards into consideration has been designed for each criterion. This is to equip each user of the manual to know how to implement the criterion they should meet in order to be approved as an MBR. This SOP number that includes the related Evaluation Area alphabet letter will be listed next to each criterion as a reference.D RAF TEvaluation ElementThese are sub-areas under the main evaluation area.Element Breakdown QuestionnaireThese evaluating questions are the equitable Grading Criteria Questions, put together by delegates of the MBR Associations and SAIA that need to be complied with in order to receive certified grading.Element Breakdown NotesNotes regarding the matching grading criteria question are made when further information or documentation copies are needed.D R A FTSR or NSRThere are two types of Motor Body Repairers, Non-structural Repairs and Structural Repairers. The checklist has been created to accommodate both types.

MBR系统运行调试手册(简版)

MBR系统运行调试手册(简版)一、调试设备安装完毕后,进行调试。
对各种设备进行空车调试,达到要求才能转入下一步,调试经过以下步骤:1、设备安装后,先进行清水联动试车考察设备运行状况,并做好记录:第一步,先开动风机向反应池供气,观察风机运行情况,曝气系统工作情况;第二步,向反应池中充入清水至满足浮球开启控制的要求水位高度(当反应池内水到达浮球低水位以上时,自吸泵自动开启,当水位降至浮球低水位时,自吸泵自动停止);第三步,对各种设备进行带负荷调试运行1小时,直到设备运转正常。
注意:以上过程中出水泵只在第三步试出水5分钟,观测出水泵工作是否正常,真空表是否正常,及出水管路情况,不得长时间开出水泵。
2、微生物驯化培养直至水质达标第一步,通入污水达到高水位,通入污水的同时开动风机,建议接种活性污泥以加快培养过程,并加入适量养料进行闷曝;第二步,当反应池内污泥浓度超过3000~6000mg/l,并且活性污泥性状较好时,开启抽吸泵并使其处在自控状态,此时出水量不要太大,控制在额定值的1/3到1/2左右。
同时控制进水与出水量一致;第三步,当反应池内污泥浓度超过6000~12000mg/l时且出水水质达标后才可以调整出水量达到额定值。
以上过程,当污水温度为15-20摄氏度时,此阶段大约需要30天时间。
通过接种污水处理厂的活性污泥使反应池初始污泥浓度为3000mg/l时,可以缩短微生物驯化培养时间1/3到1/2左右,冬季培养可能需要30-45天时间。
二、正常运行启动设备前应作好准备工作,MBR采用自动和手动两种控制模式,初期运行控制真空表的真空度小于0.01MPA。
自动模式时,抽吸水泵依据设定的程序以下面的方式自动运行。
1、抽吸水泵与风机联动,风机停,抽吸水泵自动停;2、当水位到达MBR池低水位以上时抽吸水泵启动,清水池高位时停止,风机和自吸泵联动,并且按照运行13分钟,停止2分钟的方式周期运行。
当气压表的负压达到0.04MPA时报警灯报警提示;3、当水位到低水位以下时,自吸泵停止但是风机按照开60分钟,停30分钟的方式周期运行,任何情况下只有风机运行时,自吸泵才运行;4、当膜堵塞造成真空表的真空度大于0.05MPA时报警停机,手动才能复位。

14一、膜生物反应器介绍膜生物反应器(MBR)是把膜技术与污水处理中的生化反应结合起来的新兴技术,也称作膜分离活性污泥法。
膜生物反应器(MBR)用膜对生化反应池内的含泥污水进行过滤,实现泥水分离。
一方面,膜截留了反应池中的微生物,使池中的活性污泥浓度大大增加,达到很高的水平,使降解污水的生化反应进行得更迅速更彻底,另一方面,由于膜的高过滤精度,保证了出水清澈透明,得到高质量的产水。

关于MBR病毒 病毒特征建立DownloadSave文档
我弟在前天中了MBR病毒病毒特征为建立DownloadSave文档存在于(系统盘符,我的是C)C:\ProgramDATA之下这是个隐藏文件夹直接输入地址便可找到别乱删东西
DownloadSave文件夹无法删除并会不停的生成EXE文件各种EXE 一般成对出现一个前面有空格一个没有这类EXE会不停地进入进程占用你的CPU 迫使你无法启动应用程序
除了这个明显特征还会在C:\Windows\System32和C:\Windows\temp下建立病毒源文件感染系统
当使用杀毒软件进行查杀时会被清除但是过段时间会重建
我有试过整个硬盘格式化并使用3个不同的系统盘进行安装还是一样会出现以上症状
看见网上说用360的系统急救箱可以我也试了结果一样
当对于这些束手无策的朋友们我有一条不太好的路可以走100%成功,但是有其它方法尽量不要使用
1.关闭电源
2.取下主板电池放一会电5秒肯定够够的当然你想观察下电池亦可以多玩会(记得绝缘)
3.安装上电池启动机子并点DEL键进入BOOT
4.对BOOT进行设置第一启动将第一启动设置为光驱当然你也可以用U盘
5.利用系统盘进行格式化硬盘我是全格式我想也应该全格式.....
6.做个系统吧
7.调节时间免得有证书问题
8.记得驱动要用新的哦
希望对您有帮助

MBR设计方案范文
MBR设计方案范文MBR(膜生物反应器)是一种利用微孔膜进行液固分离的生物反应器,具有高度的膜选择性和高效的固液分离功能。
在MBR设计方案中,需要考虑到系统的运行效率、膜的选择和性能、废水的处理效果等方面。
首先,在MBR设计中,要考虑到系统的运行效率。
为了提高MBR系统的运行效率,可以采用两段MBR系统设计方案,即在进一步提高废水的处理效果的同时,降低膜的堵塞程度,减少清洁周期。
此外,还可以引入调节循环泵控制系统,通过周期性调整循环泵的转速,降低膜的堵塞风险,提高系统运行的稳定性和效率。
其次,在MBR设计中,膜的选择和性能是一个重要的考虑因素。
膜的选择要综合考虑到膜材料的耐腐蚀性、耐压性、膜的孔径大小等因素。
一般来说,聚酯膜具有良好的耐久性和抗腐蚀性,适合一般工业废水处理;聚酮膜具有更高的耐压性和更细的孔径,适合高浓度废水的处理。
此外,还可以考虑采用中空纤维膜作为MBR系统的膜材料,其具有更高的孔隙率和更好的抗污染性能。
再次,在MBR设计中,需要考虑到废水的处理效果。
为了提高废水的处理效果,可以考虑采用前处理系统,如格栅和沉淀池等,以去除大颗粒的固体物质和悬浮物。
此外,还可以引入COD(化学需氧量)在线监测系统和PH在线监测系统,实时监测废水的处理效果,及时调整反应器的运行参数,保证废水的处理效果符合排放标准。
最后,在MBR设计中,还需要考虑到系统的稳定性和可靠性。
为了提高系统的稳定性和可靠性,可以采用并列运行的MBR系统设计方案,即将多个MBR系统并联,以提高系统的运行稳定性和容错能力。
此外,还可以在MBR系统中设置备用膜,以应对膜的损坏和堵塞情况,确保系统能够持续稳定地工作。
综上所述,MBR设计方案需要综合考虑系统的运行效率、膜的选择和性能、废水的处理效果以及系统的稳定性和可靠性。

1、产水当膜池的液位高于最低液位时(MBR 组件顶部往上0.3~0.5 m处),风机开启的情况下,阀门2关闭、阀门1及自吸泵开启,膜池产水,出来的水储备在清水池中。
当液位低于(MBR 组件顶部往上0.3~0.5 m处)最低液位时,自吸泵停止工作,进入停歇状态,(如图3.2中绿色线所示)。
2、反洗当产水池液位高于设定最低液位时,风机仍然保持开启,MBR产水停止(即自动阀门1关闭,产水泵停止运行),自动阀门2开启,反洗泵运行,MBR系统对MBR膜进行反洗,(如图3.2中红色线条所示)。
3、停歇风机继续开启,MBR产水和反洗停止运行。
整体的MBR系统产水13min,停歇2min,再产水13min,停歇0.5min,反洗1min,再停歇0.5min,进入下一个运行程序,如此循环进行,其整体运行程序见表3.1。

一、 膜生物反应器简介膜生物反应器(MBR )是把膜技术与污水处理中的生化反应结合起来的一门新兴技术,也称作膜分离活性污泥法。
最早出现在20世纪70年代,目前在世界范围内得到广泛应用。
膜生物反应器(MBR )用膜对生化反应池内的含泥污水进行过滤,实现泥水分离。
一方面,膜截留了反应池中的微生物,使池中的活性污泥浓度大大增加,达到很高的水平,使降解污水的生化反应进行得更迅速更彻底,另一方面,由于膜的高过滤精度,保证了出水清澈透明,得到高质量的产水。
不管被处理的污水类型如何,也不管采用何种商业化的MBR 工艺,对于所有的好氧MBR 工艺而言,都能获得非常高质量的出水水质。
所有MBR 的共同特点是:有机物与营养物质的高速度和高效率去除、固体物质完全去除、优良的消毒特性以及占地面积小。
膜生物反应器(MBR )由膜的使用状况不同分为内置式和外置式两种。
内置式是将膜直接浸渍于生化反应池中,直接从膜元件中抽出净水,而外置式则是用泵将生物反应池的水通过膜组件进行错流过滤循环,得到洁净的透过水。
内置式膜反应器由于操作压力低,使用的膜面积较大,而外置式膜生物反应器由于是在泵的压力下大流量循环错流过滤,膜的通量较大,使用的膜面积较小,但动力消耗较大。
目前,世界上投入运营的膜生物反应器大约有55%是内置式的。
我公司生产的FP 系列帘式膜组件是专门适用于内置式膜生物反应器的膜组件。
而MOF 系列膜组件则是外置式膜生物反应器的首选组件。
本手册是专门讲述FP 系列膜组件的使用说明。
筑龙网w ww .z hu lo ng .c om二、中空纤维帘式膜组件专用于MBR 的FP 系列膜组件由于外形象门帘而被称为帘式膜,是由中空纤维微滤膜、集水管、树脂槽及封端树脂浇铸而成的膜分离单元。

三、设计指南3.1原水条件:FP 系列中空纤维膜组件为浸渍式膜组件,用于膜生物反应器(MBR )。
在膜生物反应器中,原水中的有机物污染物的去除与传统活性污泥法一样,都是通过微生物分解,中空纤维膜主要起到分离生化后水和污泥的作用。
代替常规的二沉池,节约大量的土建费用和占地面积。
在处理工业污水时,应首先考虑原水中是否存在对膜组件有损害的有机物质,以及这些物质的可降解性。
当污水中溶有微生物很难分解的高分子物质时,应事先咨询。
通常事先需要进行充分的小型运转实验进行确认。
3.1.1中空纤维膜使用环境对油脂的要求当水中含有油脂时,随过滤的进行,油脂成份会广泛覆盖膜表面,从而有可能堵塞微细孔,因此原水最好不要含有过多的油脂,在N-HEX 值(正已烷提取物)超过50mg/L 的情况下要进行气浮除油,降到50mg/L 以下。
在含有矿物质油的情况下,有可能对膜产生更恶劣的影响,因此在有矿物质油存在时,N-HEX 值应降到3mg/L 以下后方可使用膜分离活性污泥法。
3.1.2中空纤维膜使用环境对消泡剂的要求在MBR 运转初期,污泥起泡时,有时需加入消泡剂。
此时请使用高级乙醇系列消泡剂。
硅胶系列消泡剂不能使用。
这是因为硅胶系列消泡剂被吸附到膜表面时,会加快膜间压差的上升,而且硅胶引起的压差上升,属不可逆的膜污染,无法恢复,所以严格杜绝使用硅胶系列消泡剂。
3.1.3其它MBR 在运行中,膜间阻力(压差)的上升主要是由于溶解在原水中的未处理有机物被吸附到膜表面引起的,有时会妨碍稳定运转。
在处理前级使用絮凝剂时,末凝聚的凝聚剂(如PAM ★)有时同样会妨碍稳定运转,应注意不要让未凝聚的絮凝剂流入膜生物反应池中。
对于一般工业排水中的物质,通常事先需要进行充分的小型运转实验进行确认,研究膜分离活性污泥法是否合适。
需要确认的事项主要如下所示:筑龙网w ww .z hu lo ng .c om处理原水时,膜的压差上升是否急剧; 用药液清洗后是否能恢复原来的通量; 压差恢复后,能否再次进行稳定运转。
★PAM :聚丙烯酰胺絮凝剂3.2活性污泥条件3.2.1污泥浓度MLSS建议适用范围5000-8000mg/L (min :3000mg/L 、max :10000mg/L )。
(1)根据膜分离活性污泥法,使用膜来进行固液分离,与通常的沉淀法不同MLSS 能够保持高浓度,通常MLSS 浓度在5000-8000mg/L 的范围内运转。
(2)当污泥浓度超过上限时膜的压差会急剧上升。
(3)当确认接种污泥的MLSS 浓度低于3000mg/L 时,在正常运转之前,可用以下的操作来提高浓度:膜的通量设定,要比正常运行低一些[4L/(m 2.h)];持续空曝养泥一些日子,时间视现场情况而定; 驯养污泥时要定期排出上清液 3.2.2生物处理 (1) 温度污泥进行生物处理顺利与否是膜稳定运转的必要条件,用一般活性污泥法进行生物处理时,为达到良好的处理效果,生物曝气池内的水温最好保持在15-35℃以内;(2) 活性污泥的状态★活性污泥的状态恶劣或者MLSS 的值偏离最佳值时(驯化污泥时等),未处理的有机物等在过滤时附着到膜表面,并加快膜的压差上升,妨碍稳定运转。
此时,请把膜过滤通量设定得比通常低[4L/(m 2.h) ]以下,或停机驯养污泥或者排泥,整顿生化状态。
(3) 恢复运行整顿生化状态后再启动膜过滤出水时,请事先确认活性污泥的生物处理是否恢复到了良好稳定运行状态。
同时应按照标准过滤通量[10~12L/(m 2.h)]的设定筑龙网w ww .z hu lo ng .c om值再次运转。
★测定污水实验方法所示的活性污泥沉淀率时,活性污泥的上层澄清液处于浑浊状态,此时,活性污泥不好,处于恶劣状态。
测定活性污泥沉淀率通常为SV 30,使用膜分离活性污泥法时,由于MLSS 浓度较高,一般添加4倍量的处理水来稀释。
3.3膜生物反应池内的配置3.3.1旋回流在膜分离活性污泥法中,利用生物处理所必需的供给微生物氧的曝气形成旋回流,同时进行膜清洗。
在此过程中由曝气管中供给的空气均匀吹向纤维膜,使膜丝产生摆动,利用曝气形成的活性污泥流进行膜清洗,如下图所示(1) 膜下部产生的曝气,在膜组件内部发生上向流。
使用上向流和空气气泡来清洗膜;(2) 在膜部形成上向流很关键,因此必须确保与上向流相均衡的下向流区域。
这样形成均匀的上向流和下向流,并在膜生物反应池内形成大的旋回流,这是稳定运转所必需的条件。
3.3.2平面布局(1)膜组件单元的平面布局尽可能位于曝气槽内的中央,并确保前后左右有足够的空间。
空间为膜组件外形尺寸的30%以上。
在膜生物反应池内设置膜组件时平面布局建议如下图:筑龙网w ww .z hu lo ng .c om注:图中>0.3X 和>0.3Y 处不满300mm 时,以300mm 为标准 (2) 帘式膜组件要按膜丝垂直方向安装,上、下集水管的间距,要比膜组件自然垂直的尺寸短一些(约短15~30mm ),为了保证膜丝具有较好的松弛状态;(3) 膜单元中,建议每片膜组件之间距离不少于100mm ; (4) 采用多个单元时,每个膜单元之间都必须保证上述空间。
3.3.3断面布局以通常运转时最低水位为准,设计本组件的断面布局,以确保上下空间。
对于膜组件的上下部,确保以下空间:(1)膜组件的上面至水面(最低水位)的距离,最低500mm 。
(2)曝气管与组件下部之间的距离200-300 mm 之间,最低不能小于180 mm 。
(3)曝气管与曝气池(箱)底面之间的距离150-250 mm之间,最低不能小于150 mm 。
断面布局建议如下图所示。
筑龙网w ww .z hu lo ng .一般说来此种布局目的是为了确保形成均匀的旋回流空间。
布置时请确保膜组件的上部和下部有足够的空间,使膜区内部的上向流和膜区外部的下向流处形成均匀的旋回流。
3.4产水方法3.4.1产水量设定(1) 过滤通量标准值中“m 2”表示膜组件的有效过滤面积; (2) 正常运行时,建议采用定流量过滤方式;(3) 随着运转的继续,膜的压差会上升,对压差变动的监视是运转管理的关键。
请保持跨膜压差<50kpa ;(4) 这里给出的过滤通量为时平均值。
实际上,运行时由于要进行间歇出水,瞬间的膜过滤通量会比此值大。
3.4.2产水泵的设定(1) 产水时出水管路中的吸引压力(负压)很低,一般在5~30 kpa 左右,因此出水泵通常设定为自吸泵。
(2) 在产水泵的出水侧设置流量传感器,通过变频控制流量,使出水泵的流量筑龙网w u lo ng .c om一定,进行定流量过滤。
(3) 出水泵选定为自吸泵时,容易确保吸引压力。
另外,运转停止后,再次进行运转时,能够容易排出管中的空气 3.4.3间歇出水的设定(1) 在膜过滤时,膜表面会堆积污泥的凝聚体和微粒子,在长时间连续出水时,即使有曝气形成的空气气泡和上向流冲洗擦洗膜表面,膜表面仍会有污泥堆积。
