摘要我们人类接触最多的就是城市污水，而城市污水，又可细分为工业污水和生活污水。而在高校里的污水指的是生活污水。生活污水的性质条件与人们的生活习惯相关，当然还包括环境气候条件，生活污水所占比例，采用生么样的排水制，国家，地区，有关部门对水质的要求等等一些方面。对于城市污水的排放，要满足《城市下水道污水排入水质标准》（CJ3082-1999）而对于排放到水体当中的污水，要满足《污水综合排放标准》（GB8978-2002）。82662

本文研究的对象是某高校新校区，其中对于2000m3/d的生活污水采用的工艺方法进行处理回用的是氧化沟工艺，氧化沟又名连续循环曝气池。氧化沟不仅有着推流反应的优点，还有着完全混合反应的特点，是活性污泥法的一种变形形式。

氧化沟工艺与其他污水处理的工艺不同，本文拿氧化沟工艺和其他污水处理工艺进行了对比，最终根据数据的对比以及实际条件的需要，选择了氧化沟工艺。氧化沟工艺在污水处理工艺技术研发上起着承上启下的作用，由于其出水的水质好，运行稳定，管理起来简单方便等一些技术性特点。一直被人们广泛使用，现如今，氧化沟处理的规模不断扩大，不仅能处理城市污水，还能处理石油废水，造纸废水，化工废水，印染废水等。

ABSTRACT At present, urban sewage is pided into industrial and domestic sewage。 In the University, the sewage is the life waste water。 Sewage nature conditions and people's living habits, of course also includes environmental and climatic conditions, the proportion of sewage, by what the drainage system, national, regional and relevant departments on the water quality requirements, and so on。 While urban sewage discharge, to meet the "urban sewage discharged into water quality standards" (CJ3082-1999) and discharge into the water, to meet the "integrated wastewater discharge standard" (GB8978-2002)。

In this paper, the 2000m3/d of the new campus of a university is used in the process of the oxidation ditch process, the oxidation ditch, also known as the continuous cycle aeration tank。 The oxidation ditch has the advantages of both push flow reaction and complete mixed reaction。 It is a kind of deformation of the activated sludge process。

Oxidation ditch process and other sewage treatment process is different, this paper took the oxidation ditch process and other sewage treatment processes were compared, and ultimately chose the oxidation ditch process。 Oxidation ditch process in wastewater treatment technology research and development plays a role of connecting link between the preceding and the following, due to the effluent water quality is good, stable operation, and the management is simple and convenient, and some technical characteristics。 Has been widely used, and now, the scale of oxidation ditch treatment continues to expand, not only to deal with urban sewage, but also the treatment of oil wastewater, papermaking wastewater, chemical wastewater, printing and dyeing wastewater, etc。。

Key words: domestic sewage; oxidation ditch process; other sewage treatment technology
