摘要
本文对河水紫外线消毒进行了研究。得到了水的浊度、水层厚度以及辐射时间与总大肠菌群存活率之间的相关关系。试验结果表明，当浊度≤１２度，水层厚度≤７２ｍｍ，辐射时间为５分钟时，消毒后出水中的总大肠菌群数≤３个／Ｌ，并且电耗为０．２９ｋｗｈ／ｍ３。
Ultraviolet(UV) disinfection of river water was investigated.The correlation relationship between turbidity,depth of water ,time of exposure and survival gxte of total coliform reoup was obtaind.The results showed that tota coliform group in effluent did not exceed 3 cout/L, and 0.29 kwh/m 3 electrical eneegy was used up,where turbidity,depth of water and time of exposure were less than or equalted,72mm and 5 minutes,respectively.
