| 摘 要： | 目的]为研究加氯消毒过程中细菌物质生成卤代乙腈的情况。方法]对水体中常见的5种细菌，按照UFC方法，测定了其生成N-DBPs和HANs的量，同时考察了溴离子对细菌加氯形成HANs的影响。结果]细菌B1的单位耗氯量最大（1．96mgCl3／mgC），B5最低（0．45mgCl2／mgC）；5种细菌加氯处理后有微量的TCAN生成，生成的DCAN随细菌TOC浓度呈近似线性关系；氯代HANs生成量占总HANs比例减少，溴代HANs随溴离子浓度的增加而在一定程度上增加。结论]5种细菌均能生成HANs，以DCAN为主；溴离子对细菌物质生成HANs的影响较大。

| Abstract: | Objective] The study aimed to research the haloacetonitriles formation by cellular material during chlorination disinfection process.Method] 5 bacterial cultures which are common in water were chlorinated according to the UFC methods to determine the HANs formation,and the effect of Br-was investigated.Result] The specific chlorine demand of B1 was the maximum(1.96 mgCl2/mg C),while that of B5 was minimum(0.45 mgCl2/mg C).There were few TCAN formation of these 5 bacteria,and their DCAN formation showed a... |
