| 摘 要： | 以乐果为目标化合物,探讨了活性炭吸附、活性炭吸附-混凝沉淀工艺以及石灰碱解-活性炭吸附-混凝沉淀三种工艺对乐果的去除效果.结果表明,乐果的去除效果随着活性炭投加量与吸附时间的增加而增加,采用活性炭吸附-常规混凝沉淀工艺对乐果的去除效果要略好于单独采用活性炭吸附,但这两种工艺都不能有效去除水中的乐果.采用石灰碱解-活性炭吸附-混凝沉淀工艺时,乐果的去除率随着石灰碱解的pH值升高而增加.当原水乐果含量为0.182 mg/L,用石灰调节原水pH值为9,投加30 mg/L活性炭吸附20 min后,去除率达89.9%,沉淀出水乐果浓度为0.018 4 mg/L,满足标准要求.

| Abstract: | Removal efficiencies of Rogor were investigated with activated carbon adsorption,activated carbon adsorption-coagulation and sedimentation,lime alkaline hydrolysis-activated carbon adsorption-coagulation and sedimentation.The result showed that removal efficiencies of Rogor increased with activated carbon dosage and adsorption time.Activated carbon adsorption-conventional coagulation and sedimentation was better than activated carbon adsorption,but both of them were not very effective.Removal rate of Rogor ... |
