【摘要】 以黄河为样本,研究了不同的絮凝剂、pH值、加氯量、接触时间、反应温度对饮用水中氯仿生成量的影响,并讨论了各种因素与氯仿生成量的关系。结果显示,氯化铝为较理想的絮凝剂,氯化消毒过程应尽量控制在较低的pH值下进行,应适当控制加氯量,并严格控制反应时间,以减少三氯甲烷的产生;还应注意的是,氯仿的浓度在冬季和春季浓度较低、夏季和秋季较高。更多还原

【Abstract】 The paper studies the different flocculants,pH value,added chlorine,contacted time and the influence of reaction temperature to the formation of chloroform in drinking water and discusses the relationships between various factors and chloroform formation by taking the Yellow River as an example.The outcomes show that alumina is ideal flocculant,the lower pH value should be controlled in chlorination,properly control the quantity of added chlorine and strictly control the reaction time for reducing the production of trichloromethane and;it also should pay attention to that the concentration of chloroform is lower in winter and spring and higher in summer and autumn.更多还原
