铁路车站污水处理工艺选择初探

Discussion of Waste Water Treatment Process of Railway Station

铁路车站污水作为污水处理的一个特例,具有污水量少,一般建设时远离城市中心,无配套市政管网可以接入,需要自行处理达标后就近排放或贮存等特点。目前污水处理工艺繁多,而车站污水处理主要以SBR工艺、厌氧污水处理工艺、人工湿地工艺为主,这几种工艺中,各有优缺点及适用性,应针对不同的污水情况予以设计,以使所设计工艺能够达到良好的运行效果。

The wastewater of railway stations,a special field,is characterized by small output,long distance from downtown and no access to the municipal network.Wastewater should be processed before discharge or storage.At present the water treatment process is very complicated.Water treatment used in station mainly includes SBR,anaerobic wastewater treatment processes,and artificial wetlands process with their respective merits and defects which shall be taken into account during design and operation so as to achieve better effects.
