Abstract

Abstract:

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.

Key words: wastewater, drinking water, activated carbon, disinfection by-products

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。
