生活垃圾焚烧发电厂渗滤液蒸发浓缩处理
Treatment of leachate from municipal solid waste incinerator plants by evaporation
摘要
Abstract
Treatment of the original and electrocoagulation pretreated leachate from municipal solid waste incinerator plants(MSWIP) by a vacuum evaporation method was investigated.The results showed that electrocoagulation pretreatment of leachate did not have significant effects on the changing trend of COD and NH3-N in the evaporation process,i.e.COD concentration in the distillates was higher in early and latter period of the evaporation,while NH3-N evaporation occurred only in the early period.Besides,pH had a significant effect on COD and NH3-N removal during the evaporation treatment process.Under acidic condition low COD removal and high NH3-N removal were obtained,but under neutral and alkaline conditions,COD removal increased sharply and NH3-N removal decreased.In addition,experiments on dual evaporation treatment revealed that the COD and NH3-N concentrations of the distillates of both leachates with and without electrocoagulation pretreatment are lower than 100 mg/L and 15 mg/L,respectively.关键词
