摘要
近年来 ,国内已有 1 0余个省区城市供水系统中先后发生了摇蚊幼虫 (红虫 )污染事件。文章介绍了国内外供水系统摇蚊发生概况 ;分析了供水系统中摇蚊发生的 3个主要原因 :原水环境污染 ,水处理过程摇蚊污染和二次供水污染。简要回顾了国外供水系统摇蚊污染防除的历史和进展 ;重点介绍了目前国内供水行业所采用物理、化学以及生物的方法在水厂净水处理及二次供水过程防除摇蚊污染的研究 ;同时指出了当前有关研究和实践中存在的主要问题是对摇蚊生物学和生态学等知识的缺乏。
In recent years,chironomid larvae(blood\|worm) infesting municipal water supply system took place more than 10 provinces in China.Chironomid pollution may result from the primary water pollution, the pollution in the process of purifying water, and the pollution in the secondary water supply system.The history and advance in prevention and control of the bloodworm in festing municipal water system are reviewed.Physical,chemical and biological control methods in the purifying water process and the secondary water supply system in Chinese water supply industry are discussed.Biological and ecological knowledge on chironomids is crucial in prevention and control of chironomid pollution.
