微污染水源水强化出水水质技术研究

文章主要阐述了针对目前中国微污染水源水的特点及许多自来水厂普遍存在的水质问题,对生物强化过滤技术的应用进行了较深入的研究。生物活性滤池由于出水的亚硝酸盐氮浓度较低,因而节约了氯耗,减少了消毒副产物的生成,强化了出水水质,具有更高的水质安全性。生物强化过滤工艺既可以起生物过滤作用,又不增加任何新的设施,是一种易为水厂接受、经济实用的解决微污染饮用水源问题的有效途径,对保证水质安全及生产应用都具有非常重要的意义。

Study on Application of Bio -enhanced Filtration in Micro -Polluted Raw Water

This article mainly elaborated the characteristics of micro -polluted source water and common problems of water quality existing in China＇s waterworks, and then made an in - depth research on the application of enhanced biological filtration technique. Due to the low density of nitrite nitrogen in the effluent of biological activity filter tank, the consumptions of chlorine were saved and the quantities of by - products from the process of disinfection were reduced, so the quality and security of the wa- ter quality was better. The techniques of biologically enhanced filtration not only have biological filtering function, but also have no need to add new facilities. It is an economical, practical and efficient way to treat the slightly polluted drinking water and also easy to be accepted by the waterworks. This is of great significance to ensure the security of water quality and water supply.
