| 摘 要： | 对珠江地区B水厂净水工艺中蠕虫的分布进行了现场调查,并结合净水工艺特征和检出蠕虫的生活习性等,对其分布规律和污染类型进行了研究。结果表明:B水厂净水工艺中蠕虫优势种属为仙女虫、线虫和摇蚊幼虫。仙女虫虽然有88.4%可被混凝沉淀和砂滤拦截,但进入BAC池后会大量孳生,出水平均密度高达18.94个/m3。各净水单元均对线虫有较好的拦截效果。摇蚊幼虫虽然也能被净水工艺有效拦截,但会在沉淀池大量孳生。从污染类型来看,线虫以原水输入的外源型污染为主,仙女虫和摇蚊幼虫则以二次繁殖引起的内源型污染为主。其中仙女虫污染暴发位置在BAC池,摇蚊幼虫则在沉淀池。净水工艺中蠕虫分布规律和污染类型均与蠕虫生活习性和净水工艺特点相关。 |
| 关 键 词： | 净水工艺 蠕虫 分布 污染类型 |

| Abstract: | Based on the spot investigation of the worm distribution in water treatment process in water treatment plant B,the water treatment process characteristics and worms' life styles,the distribution rules and contamination types of worms in water treatment process in water treatment plant were studied.The results showed that the dominant species in water treatment process were Naididae,Nematode and Chironomid midge.Although the 88.4% Naididaes could be removed by coagulation sedimentation and sand filter,it wou... |
