生物砂滤系统除微污染水源水色度与浊度的试验研究

Study on Chromaticity and Turbidity Removal in Micro-Polluted Source Water by Biological Sand Filtration System

采用生物砂滤系统对微污染水源水去除色度和浊度进行分析研究，结果表明，生物砂滤系统对微污染水源水色度和浊度的去除效果明显优于常规净水系统。在常温和低温条件下，生物砂滤池对色度的去除率分别为20—40％和8—20％，对浊度的去除率分别为77—89％和60—80％；生物砂滤系统与常规净水工艺系统对色度的去除率分别为57％、30％，对浊度的去除率分别为90％、60—80％；因而生物砂滤系统对于提高饮用水水质，保证人体健康具有重要意义。

The effect of chromaticity and turbidity removal in the micro-pollutea source water by biological sand filtration system has been studied. The results show that biological sand filtration system is excelled to conventional water treatment in the side of removal chromaticity and turbidity, the biological sand filter can reach a chromaticity removal effciency of 20 - 40% and 8 - 20% under the conditions of normal and low temperature, at the same time, a turbidity removal efficiency of 77 - 89 % and 60 - 80 % ; The removal rate of the chromaticity is 57% and 37% respectively by biological sand filtration system and conventional water treatment, and the turbidity is 90% and 60- 80%. Therefore, biological sand filtration system has great significant in improving drinking water quality and assuring people＇ s health.
