Study on the performance of different typical filters under the influent of high algae-laden water
摘要
Abstract
The study on the performance of different typical filters under the influent of high algae-laden water may provide many basic theories and technical supports for the drinking water treatment plants’ operation and design under the influent of high algae-laden water.In surfaced water treatment plant,a large number of algal cells flow into the filter,which can easily block the surface filtration media,cause dramatically increase water head loss and shorten the period of filter. Through simulation experiment of the different typical filter columns,the resistance load capacities of high algae water between the different typical filters were researched.This study comparatively analyzed the change in effluent water,such as the turbidity,distribution of particle number,the amount of algae, the time of filtration cycle,head loss and so on.The results indicate that coal-sand filter has strong ability to resist impact load for high algae water,and that filtering cycle hour is much longer which can amount to about 20 h;GAC filter,gradating material filter and homogeneous sand filter have weak ability to resist impact load for high algae water with filter cycle shortened half.The initial filter water quality is poorer,but improving over time;Algal cells are mainly adhered and intercepted by the surface filter material which removed 97% algal cells.关键词
