MSBR工艺在高排放标准污水处理厂的应用

Application of MSBR Process in Wastewater Treatment Plant with Stringent Discharge Standard

某高排放标准污水处理厂生化处理采用10单元MSBR工艺,主要介绍了10单元MSBR工艺原理、工艺设计、调试过程及实际运行情况。运行结果表明,新型10单元MSBR工艺出水主要指标达到《地表水环境质量标准》(GB 3838—2002)准Ⅳ类水质(TN≤10 mg/L)指标限值,具有占地面积小、进水碳源利用率高、脱氮除磷效果好等优点,是一种可用于高排放标准污水处理厂的先进生化工艺方案。

The process principle,design,commissioning and actual operation effect of a ten-unit MSBR process for biochemical treatment in a wastewater treatment plant with stringent discharge standard were discussed.The results showed that the major effluent quality indicators(TN≤10 mg/L)reached level quasiⅣcriteria in Environmental Quality Standards for Surface Water(GB 3838-2002)and the process had the advantages of small footprint,high utilization rate of influent carbon source,high removal efficiency of nitrogen and phosphorus.Thus,the designed process could be used as an advanced biochemical treatment process for wastewater treatment plant with stringent discharge standard.
