10000m3d城镇生活污水处理工艺设计 毕业论文+任务书+开题报告+外文翻译+CAD图纸

ABSTRACT：The main of this graduate design is about the design of the sewage treatment plant whose capacity is 1000m3/d.The technics of the plant is the inverted A2O process. The main task of the design is based on the nature of the city sewage, the size of the requirements to the sewage treatment plant preliminary design .

The task of the primary design is that a design book、a plan of the plant、the high drawing of the treatment of sludge and sewage; In the single disposal build design, the harvest is that the section plane drawing、the plan and some part magnifying drawings of the inverted A2O process.

The construction of this plant is 10000 m3/d.

The task of the primary design includes: grid, sink sand pool, inverted A2O reaction tank, sedimentation tank, contact disinfection tank, sludge concentration tank design and calculation of design calculation, reversed A2O reaction pool including design and calculation of the anoxic tank, anaerobic, aerobic pool. The design of the plane and elevation of the wastewater treatment plant is finally carried out.

The later water of the plant meets the level two of the National Sewage Discharge Standard .

Key words：domestic sewage  The inverted A2O process, Taking off the nitrogen and the phosphorus
