所谓直接过滤法区别于传统的混凝沉淀过滤工艺系指不需反应沉淀池的过滤工艺。这种新的工艺之所以能被接受并用来在某些情况下代替传统的混和反应、沉淀和过滤工艺,最主要的原因在于其可降低成本费用的吸引力。根据国内外的工程研究结果,
The so-called direct filtration method is different from the traditional coagulation and sedimentation filtration process refers to the reaction without sedimentation tank filtration process. The main reason why this new process is accepted and used to replace the traditional mixed reaction, precipitation and filtration processes in some cases is its attractiveness to reduce costs. According to the engineering research results at home and abroad,
