摘要
城市污水再生利用能够有效提高水资源的综合利用率、减轻水体污染。但是,污水处理厂二级出水有机物含量高、微生物含量高等特点制约了它的规模应用,同时二级出水中溶解性有机物也是消毒副产物的主要前体物,影响水质及环境稳定。本文利用水体溶解性有机物(DOM)的化学分级表征法即树脂吸附分级法,对氯的消毒反应对二级出水中有机物分子量分布特性、化学分布特性及消毒副产物生成潜能的影响现状进行总结概括,并提出现有研究的不足及今后可供研究的方向。
Urban reclaimed water can effectively improve the comprehensive utilization of water resources and reduce water pollution. However, high contents of organic matter and microorganism in sec-ondary sewage treatment plant limit its widespread use. The dissolved organic matter in secondary effluent is also the main precursor of disinfection by-products which can influence the stability of water quality and environment. This text will use the resin adsorption classification method of dissolved organic matter to summarize its molecular weight distribution, chemical features, and generating potential of disinfection by-product. At last, the shortcomings of existing studies are put forward and some available study suggestions in the future are given.
