摘要
选取聚合硫酸铁、聚合氯化铝、聚合氯化铝铁、氯化铝、硫酸铝五种混凝剂,对未发生水华的湖水进行混凝试验。结果显示,五种混凝剂对磷的去除效果排序为氯化铝>聚合硫酸铁>聚合氯化铝>聚合氯化铝铁>硫酸铝,对TP/TN值影响程度排序为氯化铝>聚合氯化铝>聚合硫酸铁>硫酸铝>聚合氯化铝铁。同时,在研究范围内,确定了各试剂投加量限值,即氯化铝投加量应大于8 mg/L、聚合氯化铝投加量应大于15 mg/L、聚合硫酸铁投加量应大于40 mg/L、硫酸铝投加量应大于50 mg/L。
The coagulation experiments of lake water without water bloom was carried out by using polyferric sulfate, polyaluminium chloride, polyaluminium ferric chloride, aluminum chloride and aluminum sulfate as the coagulant respectively. The results showed that the sequence of the five kinds of coagulants in removal efficiency of phosphorus was aluminum chloride 〉 polyferric sulfate 〉 polyaluminium chloride 〉 polyaluminium ferric chloride 〉 aluminum sulfate. The sequence of the five kinds of coagulants in changing TP/TN ratio was aluminum chloride 〉 polyaluminum chloride 〉 polyferric sulfate 〉 aluminum sulfate 〉 polyaluminium ferric chloride. The dosage limits of the coagulants were determined, namely the dosages of aluminum chloride, polyaluminium chloride, polyferric sulfate and aluminum sulfate should be greater than 8 mg/L, 15 mg/L, 40 mg/L and 50 mg/L respectively,
