The recycled water of Yongchuan Branch of Chongqing Yuxi Water Affairs Co.,Ltd was set as experimental material to research the effect of initial content of residual chlorine,pH,TOC、NH4+-N and temperature of recycled water on the attenuation of residual chlorine in recycled water.Based on the single factor experiment,the attenuation equation of residual chlorine in recycled water and prediction model of residual chlorine in recycled water were obtained through quadratic orthogonal rotation combination design.Through field sampling,monitoring and verifying,this model can be used to predicate the content of residual chlorine in recycled water in PE pipes.
