通过对国内外不同污水处理工艺的比较与分析，结合本工程的具体情况，最终选择A/O工艺作为本工程的处理工艺，A/O工艺流程简单，构筑物少，可节省基建费用，且运行费用低，占地面积小。
污水处理工艺流程为：进水→粗格栅→污水提升泵→细格栅→旋流沉砂池→调节池→水解酸化池→A/O池→二沉池→接触消毒池→出水
污泥处理工艺流程为：污泥泵房→重力浓缩池→贮泥池→板框脱水机→泥饼外运。

Abstract
Through to the domestic and foreign different sewage treatment process of comparison and analysis, combined with the specific circumstances of the project, the final choice of a / O process as the treatment process and a / O process simple, less structures can save construction cost and operation cost is low, covers an area of small area.
Sewage treatment process is: inflow→coarse screen→sewage lift pump→fine rack→vortex-type grit chamber→water regulating pool → Hydrolysis acidification tank→A/O process→the secondary sedimentation tank→ disinfection tank→ effluent.
Sludge treatment process is: sludge pumping room→Gravity concentrating pool
→ sludge storage tank→plant and frame filter press→transport of mud cake.
Key Words:sewage treatment;A/O process;nitrogen and phosphorus removal;sludge treatment
