MSBR与BAF工艺用于市政污水处理工程提标扩建
- Title:
- Application of MSBR and BAF Process in Upgrading and Expansion Project of Municipal Wastewater Treatment Plant
- 摘要:
- 某市政污水处理厂设计总规模为30×104 m3/d，其中一期工程提标改造规模为20×104 m3/d，二期扩建规模为10×104 m3/d。一期工程采用MSBR工艺，原出水水质执行《城镇污水处理厂污染物排放标准》(GB 18918—2002) 的一级B标准，提标改造工程增加“反硝化滤池+微砂高效沉淀池”深度处理工艺；二期扩建工程采用“初沉池+曝气生物滤池（两段式：前置反硝化+后置硝化）+微砂高效沉淀池”工艺，提标改造及扩建工程实施后出水水质执行一级A标准。该组合工艺处理负荷高、占地面积小，实际运行结果表明，各项出水指标可以稳定达到设计要求。
- Abstract:
- The total design scale of a municipal wastewater treatment plant is 30×104 m3/d, and the scale of phase Ⅰ upgrading project is 20×104 m3/d, phase Ⅱ expansion project is 10×104 m3/d. The phase Ⅰ project adopted the MSBR process, and the original effluent quality implemented the first level B standard based on Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). The phase Ⅰ upgrading project added the advanced treatment process of “denitrification filter+micro-sand high-efficiency sedimentation tank”. The treatment process of phase Ⅱ expansion project adopted the process of “primary sedimentation tank+biological aerated filter (two-stage: pre-denitrification+post-nitration)+micro-sand high-efficiency sedimentation tank”. After the implementation of the upgrading and expansion project, the quality of effluent was required to meet the first level A standard. The combined process had the advantages of high processing load and small footprint. The actual operating results showed that the various effluent indicators could stably meet the design requirements.
