一体化设备组合人工湿地深度处理村镇有机物循环利用中心废水

Integrated equipment combined with constructed wetland for advanced treatment of wastewater from village and town organic recycling center

采用A/O-MBR微电耗一体化污水处理设备组合人工湿地工艺,对村镇生活垃圾有机物循环利用中心经好氧生化处理后的废水,进行深度处理;介绍了设计参数、工艺流程,主要设备、运行情况;结果表明,出水口CODCr、BOD5、NH3-N、TN、TP五项水质指标平均浓度值分别为16.1mg/L、1.63mg/L、0.91mg/L、8.04mg/L、0.29mg/L,水质达到《城镇污水处理厂污染物排放标准》(GB18918-2002)一级A标准。

The A/O-MBR micro-electricity integrated sewage treatment equipment combined with the constructed wetland process was used to carry out advanced treatment of the wastewater after the aerobic biochemical treatment of the municipal solid waste recycling center;the design parameters, process flow and main equipment were introduced. The operation results show that the average concentration values of the five water quality indicators of water outlets COD Cr , BOD 5, NH 3-N, TN and TP are 16.1mg/L, 1.63 mg/L, 0.91 mg/L, 8.04 mg/L, and 0.29 mg/L, respectively, and the water quality meets the Class A standard of the Pollutant Discharge Standard for Urban Sewage Treatment Plants (GB18918-2002).
