Research on the Technique of Multistage Functional Filtration to Repair Black and Odorous Water

Abstract

It is of great significance for environmental protection to carry out in-depth research on the treatment of black and odorous water body and form effective water remediation technology. The ecological technology of multistage functional filtration for water restoration can be used as a new and reliable combined filtration process for advanced treatment of black and odorous river, which can effectively intercept pollutants from point sources and purify watershed water. In this paper, a new type of water purification device consisting of cobblestone, quartz sand, activated carbon and PP cotton is developed, which is used to deeply treat black odorous water body and study the filtration and adsorption performance of filter materials on target pollutants. The filtration and adsorption performance of the filter material to the target pollutants, and the influence of the thickness of the filter layer and the particle size of the filter material on the filtration efficiency were studied. The water quality was effectively improved and the purpose of treating the black odor water body was achieved.
