摘　　要：自来水加氯消毒的副产物为三氯甲烷(THMs),其主要成分为CHCl_(3)、CHBr_(3)、CHBr_(2)Cl及CHBr Cl_(2),具有一定的致癌风险。为了保证城市供水安全,可采用活性炭吸附技术去除THMs。研究过程通过吸附性能对比,筛选出4种活性炭材料,再借助静态吸附实验优选出一种吸附效果最佳的活性炭。在不同温度和不同初始浓度条件下,检验活性炭对三氯甲烷的去除率,结果显示,提高温度可改善去除效果,当初始浓度较高时,应该提高活性炭用量。The byproduct of chlorine disinfection of tap water is trichloromethane(THMs),which is mainly composed of CHCl_(3),CHBr_(3),CHBr_(2)Cl,and CHBrCl_(2),and has a certain carcinogenic risk.To ensure the safety of urban water supply,activated carbon adsorption technology can be used to remove THMs.The research process compared the adsorption performance and screened out four types of activated carbon materials,and then selected the activated carbon with the best adsorption effect through static adsorption experiments.Under different temperature and initial concentration conditions,the removal rate of trichloromethane by activated carbon was tested.The results showed that increasing the temperature could improve the removal effect.When the initial concentration was high,the amount of activated carbon should be increased.
