摘　　要：为考察生物生态工艺处理农村生活污水的实际效果,构建了一种新型生态滤池,分析了系统对有机物、营养物、颗粒物去除效果的季节特征。结果表明,系统全年对污水中COD、TN、NH3-N、TP、SS平均去除率分别为83.09%、39.35%、69.95%、44.08%、91.10%。除冬季外,系统出水SS含量达到GB 18918-2002的一级B排放标准;春季末与夏秋季,系统出水COD达到GB 18918-2002的二级排放标准。组合系统中,相对于生态滤池,厌氧反应器的贡献对COD、TP、SS的去除较大,对NH3-N的去除较小,对TN的去除略大。研究可为生态滤池的优化设计与应用提供技术支撑。To investigate the actual effect of the biological ecological process in the treatment of rural domestic sewage, a new ecological filter was built and the seasonal characteristics of the removal of organic matter, nutrients and particulate matter by this system was analyzed. The results showed that, the average removal rate of COD, TN, NH3-N, TP, and SS in the sewage throughout the year was 83.09%, 39.35%, 69.95%, 44.08%,91.10%, respectively. Except winter, the effluent SS content of the system met the first level B standard of GB 18918-2002. For the end of spring and in summer and autumn, the system effluent COD met the second emission standard of GB 18918-2002. In the combined system, compared with the ecological filter, the contribution of the anaerobic reactor was greater to the removal of COD, TP and SS, worse to the removal of NH3-N and a little greater to the removal of TN. The study can provide technique basis for the optimal design and application of ecological filter.
