生态浮床和人工湿地都是近年来在国内外采用的用于净化水质的生态修复的方法,该文章主要研究了静态条件以及不同水力负荷下,种植黄菖蒲的生态浮床与人工湿地的净水效果。试验期间进水高锰酸盐指数、TN、TP、NH4+-N平均质量浓度分别为4.74 mg/L、2.92mg/L、0.26 mg/L、1.77 mg/L。结果表明,在静态条件下黄菖蒲生态浮床对污染水体具有较好的去除效果,去除率分别为高锰酸盐指数:37.6%、TN:89.9%、TP:65.5%,对于NH4+-N的处理效果相同条件下人工湿地则优于生态浮床,去除率为92.4%。3种水力负荷0.035 m3/(m2.d)、0.06 m3/(m2.d)、0.12 m3/(m2.d)相比较,0.035 m3/(m2.d)水力负荷下,生态浮床对TP、NH4+-N、TN、高锰酸盐指数的去除率较好,分别为87.4%、66.8%、77.1%、21.16%。人工湿地则没有明显的变化趋势。通过对生态浮床和人工湿地这两种方法的净化水质的效果进行对比分析,以期在净化河道湖泊水体方面得到很好的应用。
Ecological floating beds and constructed wetlands are the methods used to purify water in the world at home and abroad in recent years. This paper mainly studies the static conditions and the water purification effect of the ecological floating beds and artificial wetlands under the different hydraulic loads . The permanganate index, TN, TP and NH4 + -N in the water during the experiment were 4.74 mg / L, 2.92 mg / L, 0.26 mg / L and 1.77 mg / L, respectively. The results showed that under the static condition, the ecological floating bed could remove the contaminated water with removal rates of permanganate index of 37.6%, TN of 89.9% and TP of 65.5%, respectively. The treatment of NH4 + -N Under the same conditions, the constructed wetland is superior to the ecological floating bed, the removal rate is 92.4%. Under the hydraulic load of 0.035 m 3 / (m 2 · d), 0.06 m 3 / (m 2 · d) and 0.12 m 3 / (m 2 · d) NH4 + -N, TN and permanganate index were 87.4%, 66.8%, 77.1% and 21.16% respectively. Constructed wetlands have no obvious trend of change. Through comparative analysis of the effects of the two methods of ecological floating bed and constructed wetland on purifying water quality, in the hope of purifying water bodies of lakes and lakes, it is well applied.
