摘要： 以自制阳离子聚丙烯酰胺(CPAM)与聚合氯化铝(PAC)复配处理模拟高岭土废水，采用响应面法建立溶液透光率与各影响因素之间的Box?Behnken数学模型，优化复配应用，结果表明最佳应用条件为：PAC投加量38.39 mg/L, CPAM投加量1.09 mg/L, 搅拌时间9 min, pH=5.18，该条件下浊度去除率可达99%. CPAM和PAC复配可在低投加量下有效加强絮凝效果，形成的絮体密实，抗剪切能力强，沉降速度快.

Abstract: A type of cationic polyacrylamide (CPAM) prepared in laboratory combined with polyaluminum chloride (PAC) was applied in flocculation of simulated kaolin wastewater. The Box?Behnken mathematical relational model between transmittance and affecting factors was established, and the conditions of flocculation performance were optimized. The optimum flocculation conditions were determined as follows: PAC dosage of 38.39 mg/L, CPAM dosage of 1.09 mg/L, rapid mixing time of 9 min and pH of 5.18. Under these optimized conditions, the transmittance of processed water arrived at 99%. The results confirmed that, compared with separately application, flocculation through CPAM combined with PAC in low dosage can be effectively. Simultaneously, dense flocs were generated in flocculation, which have a strong ability to resist shear and fast sedimentation speed.

Key words: response surface methodology, cationic polyacrylamide, polyaluminum chloride, combined flocculation
