摘　　要：考察了6种不同规格的颗粒活性炭(GAC)对饮用水消毒后产生的副产物(DBPs)的吸附效果及毒性控制情况。结果表明,投加1.5 g/L GAC、pH=7时,对DBPs吸附效果为:卤乙腈>卤乙酰胺>卤代醛、3卤代DBPs>2卤代DBPs、Br-DBPs>Cl-DBPs,表明GAC对DBPs的吸附效果与DBPs的极性有负相关性;不同粒径的GAC对DBPs吸附效果和毒性降低效果存在差异,粒径最小的GAC-F对Cl-DBPs和Br-DBPs吸附量和毒性降低效果均最高。The removal and toxicity control of disinfection by-products(DBPs)produced by disinfection of drinking water six kinds of granular activated carbon(GAC)with different characteristics were investigated.Results showed that under the conditions of 1.5 g/L GAC dosage and pH=7,GAC exhibited the following adsorption effect:haloacetonitriles>haloacetamides>haloacetaldehydes,trihalogenated DBPs>dehalogenated DBPs,Br-DBPs>Cl-DBPs.It indicated that the adsorption effect of GAC on DBPs had a negative correlation with the polarity of DBPs.The particle size of GAC impacted the adsorption effect of DBPs.Among the 6 types of GAC,GAC-F with the smallest particle size adsorbed the most Cl-DBPs and Br-DBPs,and the comprehensive toxicity reduction rate by GAC-F was also the highest.
