摘要
目的 :系统的对整个城市给水管网中 (地表水源、地下水源 )主要环节既水源水、给水处理厂入厂水、出厂水、居民二次加压设施水及居民饮用的末梢水中优势藻类及群落进行系统的毒性研究和论证 ,从而为给水的消毒 ,净化提供一些理论依据。方法 :水生生物毒性试验方法。结果 :Cl对绿球藻、蓝藻、藻类群体的毒性实验所表明 ,三种实验藻类的 96EC5 0远远大于饮用水中加氯量浓度。结论 :清除给水系统中藻类 ,用混凝→沉淀→沙滤→加氯来处理给水 ,已不能满足当前的水源水质情况 。
Objective:To discuss the role of moving algae from drinking water with chlorine and provid e so me theoretical foundation for water supply sterilization and purity. Me thods:Hydrobiology toxicity test.Results:The tocicity experiment indicated that t he three experime nt algae's 96EC50 were more greater than the amount of chlorine in the drinking wate r.It indicated that the present water control treatment didn't fit the demand o f hygiene standard of drinking water. We should enhance the research in the wate r beforehand treatment. Conclusions:The present procedure in wa ter supply system: Mix Precipitate→Sand strain→Sterilize with chlorine, which aim is getting rid of the floats and bacteria, can not get rid of those organi c substance effection.
