除了基本的去除污水中BOD和SS的要求外，通常还要求脱氮除磷，以保护水体环境。
本设计即采用了众多脱氮除磷工艺中较为经济合理的AAO工艺对进入污水厂的污水进行处理。

污泥干化场设计
3．污泥干化场设计3.1 设计参数3.1.1 干化池四周用砖石、混凝土筑成高0.8-1.0m ，顶宽0.3m 围堤。
干化池泥管采用铸铁管或UPVC 管，坡向干化池，管内流速大于0.75m/s 。
3.1.2 干化池底设防渗层（为了防止渗出液污染地下水)，用粘土（厚0.2-0.4 m ，夯实)、三和土（厚0.15-0.3m )、混凝土（厚0.1-0.15m )或其他防渗材料做，坡度取0.01-0.03 。
如果污泥干化池设在调节池上则无须设防渗层，因为渗出液正好回调节池。
3.1.3 防渗层上设排水层，以接纳下渗的污水并迅速排走以达到好的干化效果。
其排水层高度通常取100cm 。
其间用混凝土支墩将滤水层支撑住。
3.1.4 防渗层和排水层上设滤水层，一般分为三层：下层为厚100mm 的中间有许多孔洞的混凝土滤板，中间层为30 目的尼龙网，上层为厚300mm 粒径8-12 毫米的石英砂。
3.1.5 每次放泥厚度0.4-0.6m ，污泥含水率由99 ％逐渐降至65 ％-70％。
干化周期大致是春季为10 天，夏季4 天，秋季7 天，冬季8 天左右。
3.1.6 污泥干化池面积计算采用单位干化池面积可接纳污泥量或干固体量。
设两个干化池间歇使用。
干化池面积根据理论公式公及多年工程实践得出经验公式：Fs= （0.8-1.1 ) Q ，式中Q 为废水量，即电镀废水水量为1 m 3 /h 对应的干化池面积为0. 8-1.1m 2 。
3.2 为了即时将干化池中的水排走，每间隔1 米设DN65 的导流排水管，其上开许多小孔。
3.3 污泥干化池上设PVC 雨棚。
污泥干化池示意图如下：4 结论：4.1 自动化程度高，节约能源，可基本实现离人操作，污泥自动排入污泥干化池，而不需人为干预，只是将干化后的污泥运走即可4.2 投资省，不涉及设备保养及维修，因此也不会因为污泥处理不正常而导致整个废水处理站运行不正常；4.3 与机械脱水相比，其具有运行费用低，不需加药剂，不需再设污泥浓缩池及不需反冲洗等优点；4.4 采用了新式设计，在池底设了 300mm 厚的石英砂层及在干化池中加了很多导流排水管，干化效率高，而占地面积与采用机械脱水方式相差不多。

《排水工程》第71讲：污水厂污泥浓缩脱水相关计算
《排⽔⼯程》第71讲：污⽔⼚污泥浓缩脱⽔相关计算【《排⽔⼯程》第71讲】重要指数：★★★★上⼀节主要讲解污泥处理的技术路线与⽅案选择以及污泥运输等内容，详见污泥运输的4种⽅式，都分别需要注意些什么？你都会了吗。
本节主要讲解污泥浓缩部分内容。
01 污泥所含⽔分分类污泥浓缩的含义就是把含⽔率⾼的污⽔中的空隙⽔份脱除出来，以此达到减少污泥体积的⽬的。
对于污泥中的⽔份分类，主要有以下四种：空隙⽔、⽑细⽔、吸附⽔和内部⽔，每⼀种⽔份的占⽐及适合应⽤什么⼯艺脱除，分别见如下分析。
1.空隙⽔：占⽐达到65%~85%，是污泥浓缩阶段主要脱除的⽬标；2.⽑细⽔：占⽐达到10%~25%，可以采⽤⾃然⼲化和机械脱⽔脱除；3.吸附⽔+内部⽔：这两部分⽔份占⽐仅有10%，可以通过⼲燥和焚烧⼯艺脱除⼀部分，完全脱除⾮常困难。
污泥⽔份⽰意图不同浓缩⼯艺的污泥浓缩能耗⽐较▲间歇式污泥浓缩池4.有效⽔深宜为4m；5.采⽤栅条浓缩机时，其外缘线速度⼀般宜为1~2m/min，池底坡向泥⽃的坡度不宜⼩于0.05。
对于⼆沉池的设计来说，⼀种⽅法是固体负荷法，⼀种⽅法是表⾯⽔⼒负荷法，之前讲解的⽣物反应池后⾯的⼆沉池来说，⽤表⾯⽔⼒负荷法设计，⽤固体通量法校核，⽽对于污泥浓缩池来说，应⽤固体通量法设计，⽤表⾯⽔⼒负荷法校核，这两者有着这样的区别。
重⼒浓缩池总⾯积⽤以下公式计算：▲秘五公式17-21·A——重⼒浓缩池总⾯积，m2；·Q——湿污泥量，m3/d；·C——污泥固体浓度，g/L，C=1000×（1-Pw）；·Pw——污泥含⽔率；·M——浓缩池污泥固体通量，kg/(m2▪d)。
浓缩后的污泥量按如下公式计算：▲秘五公式17-26·V2——浓缩后污泥量，m3/d；·Q——原污泥量，m3/d；·P1——进泥含⽔率；·P2——出泥含⽔率。
04 ⽓浮浓缩⽓浮浓缩适合于处理易于上浮的疏⽔性污泥，或悬浮液很难沉降且易于凝聚的场合。
浮动槽排泥浓缩池工艺设计说明
浮动槽排泥浓缩池工艺设计说明一、简述及工作原理浮动槽排泥浓缩池为调节浓缩一体化池型，该池型是中心进水、周边出水的辐流式调节浓缩池。
浮动槽浮在液面上可上下移动收集上清液，使上清液连续均匀出流，底泥经排泥池内的刮泥机浓缩收集;同时浮动槽排泥池的池容满足沉淀池排泥水调节容积的要求。
浮动槽系统见图1-8-4。
该池型目前应用在国内的水厂有北京市第九水厂，水厂规模为1.5×10°m³/d，采用浮动槽排泥池3座，单池平面尺寸24m×24m;北京市田村山水厂，水厂规模3.4×10°m²/d，采用浮动槽排泥池2 座，单池平面尺寸18m×18m;深圳笔架山水厂，水厂规模5.2×10°m³/d，采用浮动槽排泥池2 座，单池平面尺寸18m×18m。
二、主要组成及结构特点浮动槽排泥池包括进水系统、上清液收集系统（浮动槽系统）、溢流系统、排泥系统四部分组成。
1）进水系统排泥水由排泥池底部中央的进水管进入，经导流筒沿径向以逐渐变慢的速度流向周边。
进泥管按最大进泥量确定管径。
2）上清液收集系统（浮动槽系统）上清液收集系统包括排泥池内的浮动槽和虹吸系统的浮动槽系统以及排泥池外的集水池和上清液泵上清液排放系统两部分。
①浮动槽。
浮动槽由浮动箱、集水槽组成。
浮动槽位于池半径的（0.75～0.8）R处收集上清液。
浮动槽上下浮动幅度一般采用1.5m。
排泥池上清液通过浮动槽底开孔进入进水槽内。
集水槽断面采用"凹"形断面，槽内流速一般在控制在0.4～0.6m/s，超高采用0.2m。
集水槽底部开孔孔口直径采用10～20mm，过孔水头损失取0.05～0.07m。
②虹吸系统。
虹吸系统包括虹吸管、阀门、水射器及导向柱等。
集水槽内的上清液通过池子四角的虹吸管，被吸入四个导向柱中。
虹吸排水系统为倒U形结构，安装在浮动槽四角的法兰支座上，与浮动槽一起浮动，出水管上设有阀门、水射器及水封装置。

我国水体污染主要来自两方面，一是工业发展超标排放工业废水，二是城市化中由于城市污水排放和集中处理设施严重缺乏，大量生活污水未经处理直接进入水体造成环境污染。
工业废水近年来经过治理虽有所减少，但城市生活污水有增无减，占水质污染的51%以上。
本设计要求处理水量为20000m3/d的城市生活污水，设计方案针对已运行稳定有效的A2/O活性污泥法工艺处理城市生活污水。
A2O工艺由于不同环境条件，不同功能的微）能生物群落的有机配合，加之厌氧、缺氧条件下，部分不可生物降解的有机物（CODNB被开环或断链，使得N、P、有机碳被同时去除，并提高对COD的去除效果。
它可以同NB－－时完成有机物的去除，硝化脱氮、磷的过量摄取而被去除等功能，脱氮的前提是NH3N应完全硝化，好氧池能完成这一功能，缺氧池则完成脱氮功能。
厌氧池和好氧池联合完成除磷功能。
