一、污水处理工艺选择与可行性分析1、污水厂的设计规模近期污水量为2×104 m 3/d ，远期污水量为4×104 m 3/d ，其中生活污水和工业废水所占比例约为6:4。

污水厂主要处理构筑物拟分为二组，这样既可满足近期处理水量要求，又留有空地以二期扩建之用。

2、进出水水质由于进水不但含有BOD 5，还含有大量的N ，P 所以不仅要求去除BOD 5 还应去除水中的N ，P 使其达到排放标准。

3、处理程度的计算1. BOD5的去除率%89.88%10018020180=⨯-=η 2 .COD 的去除率%88%10050060500=⨯-=η 的去除率%24.95%10042020420=⨯-=η 4.总氮的去除率%67.66%100602060=⨯-=η 5.总磷的去除率%80%100515=⨯-=η 4、本工程采用生物脱氮除磷工艺的可行性BOD 5：N ：P 的比值是影响生物脱氮除磷的重要因素，氮和磷的去除率随着BOD5/N和BOD5/P比值的增加而增加。

理论上，BOD5/N>才能有效地进行脱氮，实际运行资料表明，BOD5/N>3时才能使反硝化正常进行。

在BOD5/N=4～5时，氮的去除率大于50%，磷的去除率也可达60%左右。

本工程BOD5/N=3,可以满足生物脱氮的要求。

对于生物除磷工艺，要求BOD5/P=33～100。

本工程BOD5/P等于36，能满足生物脱氮除磷工艺对碳源的要求，由此本工艺采用生物脱氮除磷的工艺。

在脱氮方面，由脱氮除磷的机理可知，有机负荷是影响硝化反应的重要因素之一，在碳化与硝化合并处理工艺中，硝化菌所占的比例很小，约5%。

一般认为处理系统的BOD5负荷小于0.15kg BOD5/时，处理系统的硝化反应才能正常进行。

根据所给定的污水水量及水质，参考目前国内外城市污水处理厂的设计及运转经验，对于生活污水占比例较大的城市污水而言，以下几种方法最具代表性：A2/O法、AB法、生物滤池、循环式活性污泥法（改良SBR）、氧化沟法。
