进水主要为城市污水，由城市DN2400污水干管接入，经粗格栅及提升泵房提升后进入污水处理流程，达标后排入河流，根据环保部门要求，出水标准达到一级A标准。
工程位于，场地地貌属关中平原，土质以湿陷性黄土为主。
厂区雨水管道汇集后排入皂河内。
水厂各构建筑物抗震等级为二级，抗震设防烈度为8度。
（二）主要构（建）筑物工程数量表主要构（建）筑物工程量表（三）工期质量要求施工工期要求：天。
施工质量要求：确保合格工程。
二、整体施工说明我公司经过对施工图纸细致探讨和研究，分析了各种影响施工的不利因素和本工程的施工重点及难点，根据有关国家规范及西安市政府有关规定的要求，结合我公司的丰富的净水厂、污水厂施工经验，编制了本工程的施工组织设计。
整体施工说明如下：（一）工程特点、重难点分析及相应对策1、工程特点、重难点（1）施工工期短，工程量大，施工任务重。
施工工期有天，在较短的工期内要完成各类建（构）筑物20多座，以及厂区内各种工艺管线、给水排水管线、道路等。
（2）构筑物抗渗、抗裂要求高。
水处理构筑物大部分为薄壁混凝土结构，混凝土浇筑完毕后，由于水化热效应的影响，容易产生应力裂缝，引起渗漏，并且影响使用寿命。
（3）气象条件影响大，特别是当地多雨季节的影响。
本工程施工工期约为一年的时间，施工必定经过当地的多雨季节。
所以必须组织好雨季施工，制定合理的雨季施工措施，才能确保工期目标的实现。
（4）构筑物施工精度要求高，各种预埋管件较多并且安装精度要求高，部分圆形构筑物为预应力结构，施工难度较大。
本工程预埋套管、预埋铁件数量较大，其安装精度要求比较高。
这些预埋件的安装精度将影响到各处理构筑物的流量、流速和配水的均匀性，设备安装的准确性，因此施工时要确保土建施工的精确度和安装的准确性。
2、针对工程特点及重难点相应对策（1）针对工程量大，工期短的特点，施工时多开作业面，优化资源配置，配备足量的新型优良的机械设备、经验丰富的管理班子以及专业的施工队伍。

天津东郊污水处理厂设计实例
天津东郊污水处理厂设计实例天津东郊污水处理厂于1989年8月开工，1993年4月建成，污水厂占地29.5hm 2，工程总造价20159万元。
1. 水质水量设计处理能力为40万m 3/d ，最高日流量（不脱氮）48万m 3/d 。
进水BOD 5280mg/L ，出水40mg/L ；进水SS240mg/L ，出水60mg/L 。
2. 处理工艺流程图1 天津东郊污水处理厂工艺流程图图2 天津东郊污水处理厂总平面布置图该厂污水处理系统分4个系列，4个圆形初沉池排成一行，4个曝气池组成田字型，8座二沉池设在厂区南侧，临近北塘排水河，使处理出水可就近排入河道。
污泥处理区设在厂的西北角，5个消化池组成梅花型，污泥处理的控制室设在5个消化池的中央。
北侧设有两个沼气贮罐、污泥脱水机房和沼气发电机房等。
3、主要处理构筑物及设备参数（1）进水格栅格栅是污水处理厂的第一道预处理设施。
该厂设6台垂直格栅，由计算机程序控制。
高水位时格栅清污机将连续工作，运送格栅拦截的浮渣的皮带运输机与格栅清污机联锁运行，在所有格栅停止工作后，皮带运输机仍将继续运行一段时间。
6台垂直格栅每台宽2m，栅条净宽25mm。
（2）进水泵房设6台HLWB-10型立式涡壳混流泵，5用1备。
水泵参数：流量1.32m3/s，扬程13.2m，电机功率260kw。
泵房设有6个控制水位，控制5台泵的运行。
为避免个别水泵负荷偏高而反复启动，水泵将依次循环投入运行。
当某台泵因故障停止工作时，另一台泵将自动投入运行。
（3）曲面格栅8台曲面格栅设在沉砂池的端部。
每台格栅宽度1.2m，栅条曲率半径2.0m，栅条净距10mm。
每台格栅的清污动作根据水位模拟信号由计算机控制。
当水位差处于正常值时，清污工作将按设定时间动作；当前后水位差超过设定值时，清污工作将连续进行。
如果清污工作连续操作时间过长，计算机将发出报警信号。
曲面格栅刮出的浮渣落在皮带运输机上，皮带运输机的运行与格栅清污机联锁，清污工作停止后，运输机仍将运行一段时间。

中国城市建设研究院有限公司西南分院 610011摘要：污水处理厂的总平面布置取决于很多因素：处理厂所在的地理位置，周围的环境，交通状况，进出水方向，主导风向，厂址处的地形、地质条件，污水处理工艺流程及远近期结合等。
下面作者根据几个污水处理厂总图设计的体会，结合威远县第二污水处理厂项目的总平面布置探讨如何优化总图设计问题（附威远县第二污水处理厂项目总平面布置图）关键词：山区；污水厂厂址；厂站总平面设计；工艺流程；污水处理厂的总平面布置是污水处理厂设计中十分重要的问题，合理的总图布置方案可以节省污水处理厂的建设成本，降低运行成本，提高投资收益，改善工作环境，提高景观效果。
一、总图平面布置因地制宜，综合考虑威远县位于四川盆地中南部，东邻内江，南连自贡，西接荣县，北接资中、仁寿。
县境地跨北纬29°22′-29°47′，东经104°16′-104°53′，幅员面积1287.22km2，县城严陵镇距内江市57公里，距自贡市30公里，距省会成都市214km。
县内地形按地表形态特征分为低山、丘陵两大地貌区。
西部低山区包括山王、黄荆沟、观英滩等10镇，面积共785.45平方公里，占县域总面积的61%。
区内山峦起伏，沟谷纵横，相对高差200-300m，一般海拔500-800m，新场大堡山海拔902m，为全县最高点。
东部为丘陵区，包括铺子湾、严陵、新店等10镇，面积共501.77 km2，占县域总面积的39%。
区内多为馒头山，方山和漫岗岭脊，一般海拔300-400m，相对高差30-80m，最低处在向义镇双河口，海拔277.60m。

污水处理厂项目施工总平面布置某项目工程拟址于中华人民共和国四川省**市**村，北动为成绵高速公路，建筑场地东侧和西侧已形成的简易道路，东距绵远河仅100米，地势平坦，地形变化较小，自然地面高差1.17m。
针对以上的特征，按业主方的要求和即定的施工安排，采用如下施工总平面布置，以减少对周围居民的施工影响和场内的二次转运。
同时达到建设部“安全施工标准化现场”的要求，争创**市的“文明工地”。
第一节施工总平面布置的原则施工总平面设计的主要原则：一、场内布置施工道路，以保证场内运输。
同时施工现场设两个入口，以缓解场内交通压力。
二、现场砼集中搅拌点，成品钢筋和预制构件堆场尽可能布置在门架回转半径内，并分类堆码，尽可能减少二次转运，不得堵塞施工现场道路。
同时塔机臂幅基本覆盖整个综合厂区。
三、为不影响建筑场地周围居民的正常工作生活，在施工现场四周设置2.5m高施工围墙，进行封闭施工。
四、现场施工机械分步骤分阶段组织进出场。
五、满足施工工期的需要。
六、注重安全文明施工。
七、满足防火和生产安全的要求，现场设置消防栓。
八、减少噪声、粉尘对周围宿舍、办公区的影响。
九、周边环境及场内有限空间的美化、绿化。
第二节施工总平面布置一、施工围墙本工程地处中华人民共和国四川省**市**村，施工现场东侧和西侧已形成简易公路。
为使施工区与非施工区有效隔断，保证周围居民、路人安全。
业主方已经砌筑好一圈绕施工场地四周高2.5m的施工围墙。
同时考虑本工程建筑场地的特点，美化厂区环境，将施工围墙砌筑成景观式围墙，并在场地入口处挂七牌二图和安全警示。
二、施工现场进入口经现场踏勘，综合考虑本工程的现场条件，为保证车辆人员进出现场通畅，所需物资能及时运至现场。
决定施工现场临南侧简易公路设一个主出入口，入口宽6m，东北角设设置次出入口。
场内道路环通，以保证材料运输需要，整个施工期间对现场施工人员规定作息制度，发放通行证，以减少对周围居民的工作生活影响。
三、施工机械平面布置（一）搅拌台的平面位置搅拌台场内分四处设置，均远离施工场区的生活、办公区。
搅拌机进场时间，工程开工现场安装2台YHZ-50型移动砼搅拌站和四台JZD型搅拌机，装饰施工进入大面装饰阶段拆除2台，工程进入竣工收尾期再行拆除1台。
四、施工道路本工程施工现场根据现场条件，同时为满足施工车辆进出场畅通，不在施工现场内造成堵塞，达到标准文明化工地施工要求，现场内设专门施工道路，施工道路在场内呈“环”状布置。
作法：将场内原基层用素土夯实，作150mm厚砂夹石垫层，面层用120厚C20砼。
道路示意图如图：五、材料堆场，水泥、材料库房和钢筋木工加工房。
（一）材料堆场砂、石堆场分设于搅拌台两侧，底部采用C10砼浇筑地坪，厚100mm四周砌筑240mm的围墙。
（二）水库库房水泥库房分设于四个搅拌台附近，砼搅拌站处设置散装水泥罐30t的四个，且临近施工道路。
（三）钢筋、木工加工房本工程钢筋加工采用二套钢筋，木工加工机械。
成品钢筋堆放于钢管架上，离地200mm，并用油布遮盖。
木工加工设备一套。
（四）预制构件、装饰材料、门窗、防水材料1、预制构件堆放于枕木上，堆放场地周围设排水沟。
2、装饰材料、门窗、防水材料进入材料库房堆放。
六、行政办公、生活、施工区及临时设施的搭设为满足现场施工需要，同时减小施工区对生活办公区的影响。
现场内大致分为三个区，办公区、生活区、钢筋木工加工及砼搅拌区。
办公区和生活区主要位于施工场地东北角，钢筋、木工加工区及砼搅拌位于施工现场腹心地带及南面，且在办公区与施工区之间设绿化带，具体临设搭建要求为：1、本工程用工高峰期达500人左右，现场考虑搭设约450人的临时宿舍，结构形式为四幢层单排架结构的建筑物，面积960m2，宿舍长60m，进深6m。
2、现场设置甲方、监理办公室各一间，会议室一间，设置独立的厕所，单独设置进出的通道。
房间开间4m，其进深均为6m。
3、现场设置总包办公室，开间4～8m，其进深均为6m。
4、现场设食堂、浴室、厕所，开间6-9m，其进深为5m。
（施工总平图详本章附图部分）第三节施工给水排水平面布置本工程施工用水选择城市地下水，生活用水选择城市自来水，对砼无侵蚀作用，工程开工后，按业主方指定点接入并设置水表。
现场内排水主要依地势走向，由西向东流向。
污水经沉淀排入市政管网。
排水范围包括生活污水排放和施工生产污水排放。
具体的施工给排水平面布置如下：一、施工给水线路的平面布置（一）施工用水量的确定及进水管与支管的确定1、用水量的计算1）施工用水（q 1）由于本工程砼采取现场搅拌，由此施工用水高峰期应出现在主体施工阶段，以下为施工用水量的确定。
q 1＝Ｋ1∑————— 其中：q 1为施工用水量，单位L/SQ 1为每班工作量，本工程主体施工阶段每班工作量统计如下：砼35m ３/班，N 1为施工用水定额：浇筑砼每m 3用水量200L ，砖砌体45m 3/班，N2为施工用水定额：砌筑砖每m 3用水量2800L ，K 1为未预计的施工用水系数：取1.05。
K 2＝施工用水不均衡系数：取1.1。
则q 1＝1.05×—————————————则q 1＝1.05×———————— q 1＝7.14(L/S)2、机械用水(q 2)q 2＝Ｋ1∑————— 其中：q 2为机械用水量，单位L/S 。
Q 2为施工机械台数，对焊机一台，木工多用机1台，N 2为施工机械台班用水定额，木工多用机22L/台班，对焊机300L/台。

2、施工给水平面管网布置施工现场内的供水主管沿施工围墙明管铺设(遇道路暗设)并设现场消火栓，供水支管选用30～40mm的给水镀锌钢管，将施工用水接到各用水点。
为满足楼层、施工用水，采取在楼层外设置竖管，能使施工用水顺利送至各施工层面。
（二）施工排水线路的平面布置本工程施工排水分生活排水和施工排水，其中施工生产污水排放主要为机械用水、石灰浆沉淀液的排放，场内排水沟采用明暗沟结合，其排水沟走向基本以场内地势走向布置，平面布置如下所述：1、生活排水沟为暗沟，沿场内施工围墙、临时生活、办公设施周边布置，排水方向由北向南和由西向东，沟内排水坡度2‰，沟中排水经一级沉淀后流入场外市政污水管网内，此外厕所的生活污水经化粪池流入场内排水沟，再经一级沉淀分流入场外市政污水管网内。
2、生产用水：搅拌机械用水经一级沉淀流入生活排水沟，排水沟形式采用明沟，再由生活排水沟经二级沉淀后排入场地东侧城市市政污水管网内。
第四节施工现场用电线路布置本工程施工现场的电源位于施工场地东侧原已建简易道路侧，现场供电线路按三个回路铺设，具体布置方式如下述：一、施工现场临时用电量确定及各支线路电缆线确定（一）用电量的计算本工程施工期间最大用电容量的确定以主体结构施工阶段的施工用电量为准，这一期间投入施工机械和各自功率如下表所示：1、由此施工现场用电高峰所用全部动力设备的总功率为：1)电动机的总功率P1＝472.5KW2)电焊机额额的总功率为P2＝160KVA2、动力用电容量的计算选用K1＝0.7 Ｋ2＝0.6 cosΦ0.75P=K1∑P1/cosΦ＋Ｋ2∑P2P＝474.00(KVA)再考虑50KW的照明用电，则施工总用电容量为：P＝474+50＝524KVA应选择额定电容量为550KVA的电力变压器，方可满足现场施工用电要求，考虑到停电因素影响，现场配备一台160KW山东淮坊柴油机厂生产的柴油发电机作为备用电源。
（二）、施工用电线路截面的确定：根据计算，查表得：1.生活、照明导线选择4mm2BX型铜芯绝缘线。
2.砼搅拌机等机械用电：(分班运转，每班按2个回路计)选择2根50mm2的BX型铜芯绝缘线。
（三）、施工用电线路的安装要求1．场内动力电线路外套钢套管埋于地下200mm处引至设备配电箱，照明用电线路穿管沿墙敷设。
2．各配电箱均应按要求设漏电保护开关，所有机电设备都须有重复接地和接零装置。
（四）、施工用电线路布置现场供电线路按四个回路铺设。
第一回路满足生活及施工照明用电，导线穿塑料管沿墙敷设；第二回路满足塔吊、搅拌机、潜水泵等机电设备和龙门吊用电。
线路选择50mm2铜芯线敷设；第三回路满足交流电焊机及钢筋加工用电，线路选择50mm２铜芯线穿铁管埋地敷设。
第四回路满足铁件加工及移动设备用电，线路选择50mm2铜芯电缆。
（五）、配电箱、开关箱的设置及安装以上回路均采用380/220V三相五线制分色配制，并装好计量表，分设四个总配电箱，场内供电线路、照明线路沿墙敷设，动力用电穿钢管埋地敷设，引入各施工配电箱。
且各机电配电箱应按要求设漏电保护开关，所有机电设备都须有重复接地和接零装置。
二、施工用电线路布置见现场临时用电平面布置图第五节施工现场环境保护布置按照国家有关环保规定，进场后及时与所在区域环保部门联系，按要求控制各种粉尘、噪音等环境污染，并将工地环境卫生纳入现场总体规划。
（一）粉尘控制1、设置专人清运现场建筑垃圾。
楼层清扫前，先洒水润湿，再将建筑垃圾铲入特制加盖的斗车内集中采用塔机运到地面后处理，防止扬尘。
2、总平面范围及工地周边场地设置专人每天2～3次洒水后进行清扫，并对周围绿化地段的花草、树木定期洒水冲洗，保持洁净。
3、松散颗粒材料堆放处砌筑围墙，表面覆盖竹席，防止刮风粉尘弥漫，影响环境卫生。
