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。
As a special case of sewage treatment, the sewage of railway station has the characteristics of less sewage and general construction away from the city center, without supporting municipal pipe network to access, and need to handle the discharge or storage nearby after reaching the standard. At present, there are many sewage treatment processes, while the station sewage treatment is mainly SBR process, anaerobic sewage treatment process and constructed wetland process. In these processes, each has its own advantages, disadvantages and applicability, and should be designed according to different sewage conditions. So that the design process can achieve good operating results.
