摘　　要：采用聚合氯化铝混凝剂对藻类爆发期的兰江水进行混凝实验研究,以浊度去除效果为目标探讨了藻类对兰江水混凝效果的影响。研究结果表明:与正常期相比,藻类爆发期聚合氯化铝混凝剂的混凝效果大大降低。当混凝剂投加量由正常期的11.0 mg/L增加到藻类爆发期的20.0 mg/L时,剩余浊度反而由正常期的0.71 NTU增加到藻类爆发期的1.23 NTU,表明藻类对混凝效果产生了较大的影响。Polyaluminum chloride coagulant was used to study the coagulation of Lanjiang water during the period of algae outbreak,and the effect of algae on the coagulation of Lanjiang water was discussed in order to achieve the effect of the turbidity removal.The results showed that,compared with the normal period,the coagulation effect of polyaluminum chloride coagulant was greatly reduced during the algae outbreak.When the coagulant dosage increased from 11.0 mg/L in the normal period to 20.0 mg/L in the algae outbreak,the remaining turbidity increased from 0.71 NTU in the normal period to 1.23 NTU in the algae outbreak,indicating that the algae had a great influence on the coagulation effect.
