复合生态浮床深度处理城市废水的实验研究
|
摘要
通过构建黄菖蒲+组合填料、组合填料、黄菖蒲和空白4组不同生态浮床,研究不同生态浮床对城市废水深度处理净化。结果表明,黄菖蒲+组合填料生态浮床对城市废水进行深度处理时,COD、NH_4~+-N、TN、TP具有较好的去除效果,去除率分别为56.45%～69.23%、66.26%～81.98%、53.10%～76.06%、69.68%～80.67%,高于其他3组,其处理出水能达到GB 18918-2002的一级A标准。该工艺效果稳定,投资运行费用低,在处理城市废水领域具有较好的适用性。
Four type ecological floating bed technologies of Iris pseudacorus L and combined packing materials, Iris pseudacorus L, combined packing materials and blank control were conducted, and the effects on the purification ability of domestic wastewater advanced treatment by the ecological floating bed was investigated. The results showed that it had better removal efficiency for COD, NH4+-N, TN, TP when the domestic wastewater advanced treatment by compound ecological floating bed of Iris pseudacorus L and combined packing materials. The removal rate was 56.45%～69.63%, 66.26%～81.98%, 53.10%～76.06% and 69.68%～80.67% respectively, which was obviously higher than the other three groups, and the effluent after treatment could reach the first level A standard of the GB 18918-2002. The process has stable effects, low investment and operating costs, and has good applicability in the treatment of municipal wastewater.
