摘要
介绍了用混凝沉淀法预处理垃圾渗沥液试验。试验确定用浓度为0.1%的聚合硫酸铁作为混凝剂,并对混凝剂的投加量、pH、搅拌时间、搅拌速度、沉降时间等进行了试验研究。结果表明,混凝剂的投加量为0.5kg/m3,pH为10,搅拌速度为110r/min,搅拌时间为60s时,处理效果最佳,CODCr去除率为25%,悬浮物去除率89%。
Test of pre - treatment of waste leachate using coagulating sedimentation method was introduced, the test used Fe2 （SO4） 3 of 0. 1% concentration as coagulant, the quantity of coagulant inputing, pH, agitation time and speed, sedimentation time etc. were studied, the result showed that while the quantity of coagulant inputing is 0. 5 kg/m^3, pH is 10, agitation speed is 110r/min, agitation time is 60 s, the best treatment effect was achieved, removing rate of CODCr is 25%, removing rate of SS 89%.
