摘要
以马拉硫磷作为突发性污染物,考察了粉末活性炭对其的吸附效果。试验结果表明,粉末活性炭对纯水和滤后水中的马拉硫磷均具有较好的去除效果,对前者的去除效果更为明显,去除率随活性炭投加量的增加而升高。当马拉硫磷浓度为1.25 mg/L,纯水、滤后水中的活性炭投加量分别为12.0和20 mg/L时,反应120 min后马拉硫磷剩余浓度均低于0.25 mg/L。对滤后水而言,药剂费用约为0.06～0.08元/m3。
The adsorption efficiency of malathion by powdered activated carbon （PAC） were investigated. The result showed that a satisfied malathion removal efficiency could be obtained for pure water and filtered water with PAC, and it was batter for the former. The removal rate increased with more PAC dosage. PAC dosages of 12.0 and 20 mg/L were needed for pure water and filtered water, when the concentration of malathion was 1.25 mg/L. The residual concentrations of malathion were both lower than 0.25 mg/L after reaction for 120 min. The chemical cost of filtered water was 0.06 - 0.08 Yuan per cubic meter.
