    • The present invention provides a sewer system having a means to quickly disinfect rainwater-incorporated sewage and pollutant-incorporated rainwater, that is, combined sewer overflow (CSO), separated sewer rainwater overflow and separated sanitary sewer overflow before being discharged to public water body without passing through a sewage treatment plant, and a method and an apparatus for disinfecting rainwater-incorporated sewage and pollutant-incorporated rainwater. One embodiment of the present invention is a sewer system wherein when sewage flows into a sewage treatment plant in an amount of not more than the treatment capacity of the sewage treatment plant, the sewage is subjected to predetermined treatments in the sewage treatment plant, and then disinfection with a chlorine-based disinfectant, and thereafter discharged to public water body, and when sewage containing rainwater in an amount of more than the treatment capacity of the sewage treatment plant flows or may flow into the sewage treatment plant by a big rainfall, the amount of the rainwater-incorporated sewage of more than the treatment capacity is branched in sewer stormwater overflow removing facilities of a sewer, then disinfected with a bromine-based disinfectant, and thereafter discharged to public water body while the rainwater-incorporated sewage in an amount within the treatment capacity of the sewage treatment plant is subjected to predetermined treatments in the sewage treatment plant, then disinfected with a chlorine-based disinfectant, and thereafter discharged to public water body.
    • 本发明提供了一种下水道系统,其具有快速消毒含雨水污水和污染物引入的雨水的消毒装置,即合并的下水道溢流(CSO),分离的下水道雨水溢流和分离的卫生下水道溢流,在排放到公共水体之前没有 通过污水处理厂,以及一种消除含雨水污水和污染物的雨水消毒的方法和装置。 本发明的一个实施例是一种下水道系统,其中当污水以不超过污水处理厂的处理能力的量流入污水处理厂时,污水在污水处理厂中进行预定的处理,然后 用氯类消毒剂消毒,然后排放到公共水体,如果污水含有超过污水处理厂处理能力的雨水流入或流入污水处理厂,由于大雨, 雨水排污量超过处理能力的下水道污水下水道溢流除水设施分流,然后用溴化消毒剂消毒,然后排入公共水体,同时排放含雨水的污水量 在污水处理厂的处理能力内,在污水处理厂进行预定处理 然后用氯系消毒剂消毒,然后排放到公共水体。
