给水厂消毒副产物管控的研究

Research on the Control of Disinfection Byproducts in Water Supply Plants

饮用水在消毒处理过程中,消毒剂与水中的有机物反应生成消毒副产物,其中三卤甲烷检出量较高,影响到水质安全。通过比较4种预处理方法,分析水中三卤甲烷总量的变化情况,确定最佳的优化组合。结果表明,当高锰酸钾投加量0.8 mg/L、粉末活性炭投加量25 mg/L时,三卤甲烷总量可控制在0.5以下且成本最低。

During the disinfection process of drinking water,disinfectants react with organic substances in the water could generate disinfection by-products,among which the detection level of trihalomethane is relatively high,which affects the safety of water quality.By comparing four pre-treatment methods,analyzing the changes in the total amount of trihalomethane in water to determine the optimal combination.The results show that when the dosage of potassium permanganate is 0.8 mg/L and the dosage of powdered activated carbon is 25 mg/L,the total amount of trihalomethane can be controlled below 0.5 with the lowest cost.
