| 摘 要： | 文章研究了在模拟条件下污水厂中百菌清污染的应急处理措施。试验结果表明:投加粉末活性炭可有效地去除百菌清,确保出水达到水厂排放标准,粉末活性炭在40 min内即可完成对百菌清87%以上的吸附,投加量在1.0 g/L时,溶液中剩余百菌清的含量为痕量,在气象色谱的检测下限(0.024μg/L)范围内;混凝沉淀工艺对百菌清也有较好的去除效果,在混凝剂投加量为150 mg/L的条件下,百菌清的去除率可达85.39%;粉末活性炭吸附和混凝工艺联用可以形成互补,有效去除百菌清的同时保证处理后出水碳水分离。

| Abstract: | In this paper,the effects of emergency measures on chlorothalonil pullution under simulated conditions were studied.The results showed: powdered activated carbon can effectively remove chlorothalonil,ensuring that the quality of effluent meets the standards for water quality.Chlorothalonil decreases by 87% in 40 min by the adsorption of powdered activated carbon.With 1.0 g/L dosing quantity of powdered activated carbon,concentration of chlorothalonil remains in the solution achieved trace quantity,within the detection limit(0.024 μg/L) of gas chromatograph;Coagulation and sedimentation processes on the removal of chlorothalonil also has an ideal effect.The removal rate of chlorothalonil can be up to 85.39% with 150 mg/L coagulant.Adsorption by powdered activated carbon and coagulation processes can be combined to ensure both the effective removal of chlorothalonil and separation of carbon and water in treated effluent. |
