污水回用系统水质模型探讨

Study on the water quality model in wastewater reuse system

在分别对部分污水回用系统和全部污水回用系统进行稳定状态条件下的理论分析基础上,建立了相应水质数学模型,据此推论出当污水处理设施去除率E一定时处理水质与循环次数的数学关系,证明了在回用状态下E与其他各项参数的相互关系,进而求得了无限循环处理时的处理水质表达式,并对水质模型各相关参数特性进行了分析讨论.

When the removal efficiency（E） was fixed in sewage treatment facilities,the mathematic relations between water quality and cycle index were calculated based upon the theoretical analysis to partial treated wastewater reuse system and all treated wastewater reuse system under their stable state.Water quality was related to every parameter in those imitated system,and the expression of the water quality at endless loop was gained too,the end part was the analysis for the changing parameter.
