| 摘 要： | 研究了PAC与不同粒径的天然粘土矿物复合混凝去除给水中的颤藻。结果表明，两者复合除藻效果显著优于单加PAC。当PAC浓度为12 mg/L，矿物浓度为24 mg/L，粒径为160目时，除藻效果最好，浊度和叶绿素a去除率分别为98.2%和100%。两者复合后PAC形态含量都发生了变化，悬浮态铝含量相对增加，溶解态铝含量相对减少，总残余铝量减小。

| Abstract: | The research is based on the coagulation removal of Oscillatoria by polymeric aluminum chloride (PAC) compounded with different sizes of clay minerals. The results show that PAC compounded with clay can achieve a better coagulation effect. The removal rates of turbidity and chlorophyll-a are 98.2% and 100% respectively when the clay mineral is 160 size, its concentration is 24 mg/L and the PAC concentration is 12 mg/L. When compounded, the concentration of suspended aluminum is relatively increased while the soluble aluminum is decreased. The total residual aluminum is also reduced. |
