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。

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。
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。

A/A/O工艺生物除磷脱氮基本原理。 主要原理为：在好养段，硝化细菌将入
流污水中的氨氮及有机氮氨化成氨氮，通 过生物硝化作用，转化为硝酸盐，在缺氧 段，反硝化细菌将内回流的硝酸盐通过生 物反硝化作用，转化成氮气，在厌氧段， 聚磷菌释放磷，并吸收低级脂肪酸等容易 降解有机物，而在好氧段，聚磷菌超量吸 收磷，并通过剩余污泥排放。
