城市住宅小区中水回用工艺设计

AbstractThis design is based on the relevant data of water reuse process design in theplot,set up a process for water reuse in a community of 5000 people.The dailysewage treatment capacity in this paper reaches 22.5 m3,and the removal efficiencyof pollutants in sewage is 85%.In the residential sewage,the pollutants are mainlyorganic compounds containing carbon,nitrogen and phosphorus.This process of thisdesign is very simple and consist of hydrolysis acidification tank,regulating tank,biological contact oxidation tank,etc.The process is flexible in operation,convenient in management and economical in cost saving.The most important thingis it meets the sewage discharge standard.Key words:Residential sewage;Reclaimed water reuse,biological contactoxidation pool,process design.
