【摘要】 反粒度过滤是当前过滤技术中的重要研究课题之一.作者通过中间试验和生产性试验初步提出了该种滤池的设计、运行参数,并对运行中出现的问题及其解决办法进行了探讨.根据试验资料计算结果,反粒度过滤的过滤性能指数(FPI)比传统快滤池高5倍,如果考虑过滤前后的浊度,则性能更显优越.更多还原

【Abstract】 Inverse Graded Filtration is one of the important tasks in present filtration technology research. The design criteria and operation parameters pf inverse graded filtration have been proposed by the authors, also the problems in performance and way to deal with them were investigated in the pilot plant andfull-scale experiments. The results show that the filtrating property index (FPI) of inverse graded filtration appears 5 times higher than traditional one and it may be more advanced if the turbidities of influent and elfluent of the filter were taken into account.更多还原
