Urban sewage water pollution is large, so the urban sewage treatment and reuse is to protect the environment and ease water crisis one of the effective ways. The graduation project is about the northern suburb of Changchun City wastewater treatment plant advanced treatment process design and consideration,mechanical mixing pool,grid flocculation pool and inclined plate sedimentation tanks are adopted in this design,the effluent is made to attain The First Discharge Standard Of The secondary treatment effluent mixed by mechanical mixing pool,into the grid flocculation tank react and produce large amounts of floc,then into the inclined plate sedimentation tanks,at the same time BOD,COD,SS are last,it es into the contact pool to antisepsis,making the effluent be up to the standard of the discharge. This design content mainly includes: the urban sewage treatment methods were reviewed, process flow diagram, the main structures to determine the size, the main design and calculation of equipment type selection, sewage elevation calculation, etc. At the same time a process flow diagram, the floor plan, flocculation pool, the inclined plate, the plan of the main structures traps and section. The design of the plete will benefit of Changchun city sewage 哈爾濱理工大學(xué)學(xué)士學(xué)位論文 IV standards and relieve the Changchun city crisis of water, reduce the harm to the environment. Keywords： advanced treatment。 mixed。 flocculation。 precipitation 哈爾濱理工大學(xué)學(xué)士學(xué)位論文 IV 目錄 摘要 ...........................................................
