MFWB工艺强化处理农村生活污水的设计及试验

Design and test of treating rural domestic sewage with MFWB process

采用MFWB工艺对污染物去除效率较低的人工湿地进行改造,用于处理农村生活污水。改造后,农村生活污水中CODcr、TP、NH3-N、TN的去除率均得到了大幅度的提升,且出水一直保持在稳定的较低浓度水平,达到《城镇污水处理厂污染物排放标准》二级标准。改造具有良好效果,建议在相似工艺的处理站点进行推广。

The constructed wetland with low pollutant removal efficiency was modified by MFWB process for the treatment of rural domestic sewage. After the transformation, the removal rate of COD cr ,TP,NH 3-N,TN in rural domestic sewage has been greatly improved, and the effluent has been kept at a stable low concentration level, reaching the second class standard of Pollutants Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant. The transformation has good effects, and it is suggested that it should be popularized in the treatment station of similar process.
