摘　　要：采用腐殖酸配水,研究了氯化消毒过程中二氯对苯醌(DCBQ)、二溴对苯醌(DBBQ)、2,3-二溴-5,6-二甲基对苯醌(DBDMBQ)、四溴对苯醌(TBBQ)等卤代苯醌(HBQs)类消毒副产物的生成特性和影响因素。结果表明,腐殖酸氯化生成DCBQ和DBBQ的产率高于DBDMBQ和TBBQ。随着反应时间的增加,4种HBQs的生成量均呈现先快速升高之后保持稳定并稍有下降的趋势;随着温度的升高,HBQs的生成量呈增加趋势;弱酸性条件有利于HBQs的生成;在有效氯投加量为3~30mg/L范围内,DCBQ与DBBQ的生成量随加氯量的增加而增加,TBBQ与DBDMBQ的生成量随加氯量的增加先增加后减少;随着DOC浓度的增加,HBQs的生成量逐渐增加,其中分子质量<1 ku组分的单位质量有机物HBQs生成势最高。The characteristics and influencing factors of halogenated benzoquinones(HBQs)disinfection by-products such as dichloro-p-benzoquinone(DCBQ),dibromo-p-benzoquinone(DBBQ),2,3-dibromo-5,6-dimethyl-p-benzoquinone(DBDMBQ)and tetrabromo-p-benzoquinone(TBBQ)generated in chlorination disinfection of humic acid were investigated.The yields of DCBQ and DBBQ from humic acid chlorination were higher than those of DBDMBQ and TBBQ.With the increase of reaction time,the concentrations of four halogenated HBQs showed a rapid increasing trend at first,then tended to be stable and decreased slightly.With the increase of temperature,the formation of HBQs increased.Weakly acidic conditions were favorable for the formation of HBQs.When the dosage of active chlorine was 3-30 mg/L,the concentrations of DCBQ and DBBQ increased with the increase of chlorine dosage,while the concentrations of TBBQ and DBDMBQ increased first and then gradually decreased.With the increase of DOC concentration,the formation of HBQs gradually increased,and the formation potential of HBQs per unit organic matter with molecular weight less than 1 ku was the highest.
