摘要
采用自制的硼泥复合混凝剂(PSC)对生活污水进行处理。结果表明 :最佳 pH范围为4.5～8.5 ,PSC的投加量为1.0g/L,快搅2min ,慢搅5min,静置20min ,COD的去除率达90 %以上 ,SS及浊度去除率在95 %以上 ,pH也处于6.5～9.0范围内。该方法具有投药量少 ,工艺简单 ,沉降快 ,费用低 。
I this paper,we treat dometic sewage with boron sludge copound coagulant(PSC).The results show that the best range of pH is 4.5～8.5,wihle the quantity of PSC is 1.0g/L.After stirring quickly for 2 min,then slowly for 5 min and placing quietly for 20 min ,COD removal rate is above 90%.SS and turbidity removals are above 95% and pH is at the range of 6.5～9.0. It has the advantages of less quantty、simple technology、quick subsidence、cheap cost and high effect etc.
