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。

旋流沉砂池设计
旋流沉砂池在市政污水处理工程中的应用Design of Vortex-type grit chamber中国市政工程东北设计研究院王志红中国市政工程东北设计研究院李健大连市城市设计研究院赵建东摘要：旋流沉砂池作为污水预处理设施，在污水处理工艺中起到非常重要的作用，因为其设计技术比较成熟，池型构造比较固定，污水杂质处理率相对较高，成为市政污水处理工程中主要的选择工艺。
本文以污水处理为应用实例，论述了旋流沉砂池的沉砂机理及在其设计方法。
关键词：污水处理旋流沉砂池设计参数Keywords:sewage treatment ; V ortex-type grit chamber; Parameter function of design;1、旋流沉砂池原理及特点旋流沉砂池是利用机械力控制水流流态与流速，使砂颗粒在离心力与重力的作用下，沿池壁呈螺旋线加速沉降加速砂粒的沉淀以到达砂粒沉降的目的，原水进入平直的进水渠道后成直线流动，将进水的紊动减至最低，在池内形成沿池壁的平面旋流，该旋流流态产生的离心力产生附壁效应，使砂粒贴向池壁，并借重力落向池底。
在沉砂池中心处装有一轴向螺旋桨，用来保证池内所有水流的适当转动。
螺旋桨、入水导流板和进水水流结合在一起，就会产生环流流态。
(水流沿沉砂池周边流动，与此同时，沿平底转向中心，经叶轮向上，到顶部，再折向池壁，又再向下到池底一种螺旋环流流态) 。
在环流流态的作用下，离心力的作用使得砂粒最大限度与平底碰撞，并被水流捕集，而砂粒一旦在平底上被捕集到，就会藉环流流态所产生的底部速度被推向中央落入砂斗。
平面池底是保证环流流态到达最大除砂和与有机物别离效率的关键因素，因为坡形底面将会减少环流流态的强度，降低砂粒的捕集效率，增加水流所捕集和储存的砂粒中有机物的含量。
当砂粒沿平底被推向沉砂池中心时，旋转叶轮将加速水流流动，使得较轻的有机物被提起并返回至沉砂池的出水中去。
然后砂粒移向池心，通过螺旋桨驱动轴和钢盖板之间的环形孔口落入底部集砂斗。
