摘要
为充分利用再生水资源,将城市污水回用于农田灌溉,研究了城市污水再生水贮存技术。明确提出了城市污水再生水贮存的可行性,主要有机污染物COD、BOD5、凯氏氮、pH、硫化物、细菌等随时间与贮存池水深的变化规律;提出采用二次加氯的原理解决硫化物、细菌等超标的方法,具有广泛的适用性。
In order to make full use of regeneration water resource,the reclaimed water of urban sewage storage technology is mainly studied with the purpose of farmland irrigation by the re-usage of wastewater in city.Clearly put forward the feasibility of reclaimed water storage of urban sewage and the changeable law of organic pollutants COD,BOD5,NH3-N and pH along with the variation of time and storage pond＇s depth,Besides,demonstrating the ways of responding to over-proof of sulfide and germ： principle of re-chlorine.
