【摘要】 选取硫酸率、聚合氯化铝、聚合硫酸铁及聚丙烯酰胺作为本研究的絮凝剂,对浊度为79NTU的污水投加不同量的絮凝剂,研究投加不同量的絮凝剂,在不同沉淀时间内污水浊度的变化,根据不同絮凝剂在相同投加量、沉淀时间条件下对污水处理的效果,筛选出最佳合理絮凝剂、投药量和沉淀时间。更多还原

【Abstract】 Selecting aluminum sulphate,poly-aluminum chloride,poly-iron sulphate and poly-amide propylene as the flocculant in research,adding different dosage flocculant to the sewage of turbidity 79 NTU,the change of sewage turbidity was studied.At last,the best flocculant,dosage and sediment time were determined by the test.更多还原
