| 摘 要： | 供水流程中的摇蚊污染影响水厂生产和自来水水质，S市水厂进行的摇蚊污染特征调查结果表明，污染水厂的摇蚊优势种是花翅摇蚊，水厂孳生的摇蚊来源于进厂原水，摇蚊主要孳生分布在水厂沉淀池。水厂沉淀池形成摇蚊污染的主要原因有：原水的悬浮物和丰富的藻类，沉淀池的温度、溶解氧、pH值，摇蚊幼虫对氯离子和混凝剂浓度的较强耐受性。

| Abstract: | Since the Chironomid pollution in city water supply system causes a lot of troubles in water plant and water quality,Chironomid pollution characters in water supply systems in S city are investigated in this paper.The results show that 98% of pollution in water plants is induced by C.Kiiensis,the predominant Chironomid species in Guangdong Province;the Chironomids,which originated from source water rather than periphery of water plant,mainly broods in sedimentation tanks in water plants.The main reasons of Chironomid pollution are as follows: abundant suspended solid and alga in source water;water quality characters in sedimentation tanks,such as temperature,dissolved oxygen,pH,etc.;and the strong tolerance of Chironomid to chlorine ion and coagulator of water in sedimentations tanks. |
