摘　　要：针对含油污水开展了聚二甲基二烯丙基氯化铵(PDMDAAC)、聚合氯化铝(PAC)、阳离子聚丙烯酰胺(CPAM)3种药剂复配实验,考察了复配组合、加药顺序、加药比例对絮凝效果的影响。结果表明:在试剂加量相同的条件下,PDMDAAC、PAC、CPAM三者复配絮凝效果要优于PDMDAAC和PAC复配以及PAC和CPAM复配,且絮体紧实;通过对比实验,PDMDAAC在PAC之前加入水样的絮凝效果较好;在有机试剂总量一定的条件下,当PDMDAAC加量4mg·L^(-1)、PAC加量30 mg·L^(-1)、CPAM加量2 mg·L^(-1)时,絮凝效果最好,水中悬浮物质量浓度为18.7 mg·L^(-1)mg·L^(-1),含油量为6.15 mg·L^(-1)。The compounding experiment of PDMDAAC, PAC and CPAM was carried out for oily sewage, and the effects of compounding combination, dosing sequence and dosing ratio on flocculation effect were investigated. The results showed that the combination of PDMDAAC, PAC, CPAM was better than the combination of PAC and CPAM and the combination of PAC and PDMDAAC. At the same time, the flocs of the best combination was tight. It proved that the flocculating efficiency was better when adding PDMDAAC before adding PAC. When dosage of PDMDAAC was 4 mg·L^(-1), the dosage of PAC was 30 mg·L^(-1)and dosage of CPAM was 2 mg·L^(-1), the flocculation results was the best, the suspend solid content in water was 18.7 mg·L^(-1), the oil content in water was 6.15 mg·L^(-1).
