藻类污染对太湖流域饮用水水质的影响

目的 :探讨藻类污染对太湖饮用水水质的影响。方法 :在太湖饮用水取水口附近采集水源水 ,分析水源水中藻类的含量、分类 ,同时检测水源水、自来水出厂水水质。结果 :藻类高峰繁殖时间出现在每年 4月以后 ,水温对藻类繁殖起着一定的作用 ,太湖水源水中的含磷、含氮量以及太湖的水位也对藻类繁殖起着较大的作用。结论 :藻类大量繁殖时 (大于 1.0× 10 7个 /L时 )水厂对水源水处理出现困难 ,饮用水水质易超标。

Influence of alga contamination on the quality of drinking water in the Tai Lake area

Objective: To study the influence of alga contamination on the quality of drinking water in the Tai Lake. Method: Collecting water near the source of drinking water in Tai Lake. Determining alga categories and measuring the quantity of alga and measuring the water quality of source water and tap water and waterworks water. Result: The peak time when alga reproduces occurs since April each year, the factors influencing Alga's reproduction include the following: water temperature, water level, the content of phosphorus in water, and the content of nitrogen in water. Large amount alga causes a lot of trouble to water treatment process, meanwhile the quality of drinking water easily exceed the health criteria.
