  • 摘要: 为了研究复合人工湿地对高污染河流污水中有机污染物的去除效果及规律,实验构建了不同水力负荷下的潜流+潜流、潜流+表面流、潜流+潜流+表面流、表面流+表面流等人工湿地单元组合成的5个复合人工湿地.连续运行一年以来,各复合人工湿地对BOD5、COD和SS的去除效果分别为91.9%~94.7%、69.3%~75.8%和92.3%~93.9%,相对于多级表流湿地,多级潜流湿地更利于有机污染物和悬浮物的去除;BOD5、COD和SS主要在各复合湿地的第一级湿地单元内得到去除;复合人工湿地对COD去除效果秋夏季两季好,春冬两季差;复合人工湿地能有效去除悬浮态BOD5和COD,出水中部分溶解态有机物难以有效降解.
    Abstract: In order to investigate the organic pollutants removal efficiency and mechanism of treating the highly polluted river with hybrid constructed wetland, five hybrid constructed wetlands composed of different wetland units which were subsurface flow + subsurface flow, subsurface flow + surface flow, subsurface flow + subsurface flow + surface flow and surface flow + surface flow were constructed and operated under different hydraulic loading. During one year's experiment, the average removal rates of BOD5, COD and SS were 91.9%~94.7%, 69.3%~75.8% and 92.3%~93.9%, respectively. Compared with multistage surface flow wetland, multistage subsurface flow wetland was better in removal of the organic pollutants and suspended solids. BOD5, COD and SS were mainly removed in the first stage of all the wetland series. The COD removal efficiency was good in autumn and summer but poor in winter and spring. The suspended BOD5 and COD can be effectively removed in the hybrid constructed wetlands, but a number of dissolved organic was difficult to be degraded.
