某城市生活污水厂工艺设计

AbstractThis design,the domestic sewage treatment status of Yongchun County,and the analysisof the sewage treatment capacity of the sewage treatment facility of Yuanyuan,the analysis ofthe special features of each project,the design of the sewage treatment project.After analysisand comparison,AB process is selected.The design content mainly includes process design,structure and building design.The sequence of this process is:the wastewater removes largerparticles through the network and the granary,and then enters the key stages of this process:the adsorption tank and the sedimentation tank (stage A),under the high-load operation ofstage A,Can remove most of the organic matter,and then the sewage enters the aeration tank,sedimentation tank (stage B)for further treatment,and finally the effluent.The effluentquality meets discharge standards.The whole design process is simple in process,flexible inoperation,convenient in management,saves economic cost,and meets the requirements ofsmall and medium-sized urban sewage treatment plants.Key words:Domestic sewage;AB Technology;technological design
