摘要
以聚合氯化铝(PAC)为混凝剂,改性活化硅酸为助凝剂,通过烧杯混凝试验(处理苇水河微污染原水),研究混凝效果和确定改性活化硅酸的最佳工作参数,包括PAC的投加量,改性活化硅酸的粘度、静置时间、投加量、投加时间点及保存时间,除浊率提高到95%以上,并对处理工艺进行经济性评价。为地表微污染水资源的深度处理和利用提供科学依据。
Weishui River less-polluted raw water was treated coagulated using polyaluminum chloride ( PAC) as coagulator and modified active silica as coagulant aid through jar tests.The coagulant effect was investigated and the best activated modified active silica acid 's operating parameters were determined,including the dosage of PAC and activated modified active silica acid's viscosity,holding time, adding dosage and time as well as keeping time.The turbidity removal rate was over 95% .Moreover,the economical efficiency of treatment process was evaluated.The results can provide a scientific basis for the treatment and use of surface less-polluted water.
