- 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.
