Discussion on the Design of Treatment Process for a Long-Process Wastewater Treatment Plant in Northern China
[Purposes]Taking a newly built sewage treatment plant in a northern animal husbandry city as an example,this paper discusses the long-process sewage treatment process.[Methods]The influent indi-cators and characteristic pollutants were analyzed,and the core process of"hydrolysis acidification+bio-logical tank+coagulation sedimentation+denitrification deep bed filter+ultrafiltration membrane"was adopted to reasonably arrange and save land use.[Findings]After the treatment of the process,the efflu-ent stably met the first-class A standard.[Conclusions]The purpose is to provide practical guidance and theoretical support for similar regional and domestic sewage treatment projects.
