Purification Effect of Artificial Floating-Island Combining with Multiple Layers for Urban River Water
-
摘要: 以自制的多层组合生物浮岛为研究对象,考察了植物种类和流量对生物浮岛净化水体中CODCr和氨氮的影响,以及其对沈阳细河水体的净化效果。结果表明:种植美人蕉的多层组合生物浮岛对模拟河水中CODCr的净化效果最好,去除率为75.30%;种植芦苇的多层组合生物浮岛对模拟河水中氨氮的净化效果最好,去除率为75.76%;多层组合生物浮岛运行的适宜流量为0.75 L/h;多层组合生物浮岛对沈阳细河河水具有良好的净化效果,其对CODCr和氨氮的去除率都在50%左右。Abstract: A self-regulating multiple layers combined floating-island was used for water purification of the Xihe River, and the purification effect of plant species and flow rate on CODCr and NH4+-N studied. The results showed that the floating-island planted with canna and reed had the highest purification effect of CODCr (75.30%) and NH4+-N (75.76%) respectively for the simulated river water. The optimal flow rate was 0.75 L/h. The purification effect of multiple layers combined floating-island on the Xihe River was good and the purification effect of floating-island for both CODCr and NH4+-N could achieve 50% or so.
