摘　　要：研究不同消毒方式对城镇污水处理厂尾水消毒前后的消毒副产物的影响。结果表明,在不同消毒工艺中,尾水消毒副产物占比不同,但消毒副产物的占比呈现上升的趋势,典型含氯有机物CHCl3和CH2Cl2浓度增加。此外,NaClO的浓度越大,CHCl3和CH2Cl2的浓度越大,NaClO对CHCl3的影响较CH2Cl2大。The influence of different disinfection methods on disinfection by-products of tail water before and after disinfection in urban sewage treatment plant were investigated.The results showed that the proportion of disinfection by-products was different after different disinfection processes,but the proportion of disinfection by-products showed an increasing trend.The typical chlorine-containing organic compounds CHCl3 and CH2Cl2 showed that the concentration of the two concentrations increased.In addition,the greater the concentration of NaClO,the greater the concentration of CHCl3 and CH2Cl2,the effect of CHCl3 is greater than that of CH2Cl2.
