摘要
针对人工湿地在低温条件下处理效果较差的问题,为提高潜流人工湿地冬季运行效果。采用活性污泥挂膜和表面覆盖地膜的强化方式,开展冬季运行试验,分析试验人工湿地冬季运行经强化措施后的处理效果。结果表明,通过强化措施后,各指标平均去除效果都有较大提高,COD去除率由25%提升至49%、TN去除率由27%提升至45%、TP去除率由29%提升至51%。
For artificial wetland under low temperature conditions of the poor treatment effect, try to improve the undercurrent of artificial wetland winter running effect. Using activated sludge membrane and the strengthening of the surface film, conducting winter running tests, analysis test of artificial wetland in winter running after strengthening measures of treatment effect. The results showed that by strengthening measures, each index average removal efficiency are improved greatly;Increased from 25% to 49% removal rate of COD and TN removal rate increased from 27% to 45%, and TP removal rate increased from 29% to 51%.
