污水处理厂平面布置图

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。

2、根据工程项目，施工方案和周围环境，本着“节约成本，施工必须，适当集中”的原则，进行临时设施布设。

3、尽可能地利用场内交通条件，减少对现状交通干扰及对周围环境的影响。

4、本着经济合理的原则，按照安全生产、文明施工的要求，对施工现场进行布置。

第二节平面总体布置1、现场办公平面布置现场总平面布置图1.1 项目部布置根据现场勘查，项目部设置在厂区东侧空地处，拟搭建4125㎡项目部办公区及临舍区。
