On July 1, 2012, the country's new version " Hygienic Standard for Drinking Water " was Implemented comprehensively wit h enforcement in the nat ion, Therefore, it is a technical problem to solve for waterworks in order to produce more high-quality, safer tap water. Among t he production process of waterworks, the water purificat ion technology is one of the most important production links in t he water purificat ion treatment. Since treatment effects determine the qualit y of water produced by the waterworks, therefore, it is very important whether filtrat ion technology of the filter and the automat ion control system in the waterworks can produce qualified, safe and healthy tap water or not. Based on the reality, this paper carries on research and analysis of difficult and important points of t he filter automat ic filtering process and the automat ic recoil process, which is on t he basis
