摘　　要：人工浮床技术是治理富营养化水体的一种经济且高效的手段。应用3种填料、2种浮床、2种水力负荷对人工浮床中试系统进行组合构建,考察不同类型的浮床对太湖周边污染河水的净化效果。结果表明,采用人工浮床加挂人工填料的方法对富营养化河水进行外源污染控制是行之有效的,经过3种填料组合浮床净化后,出水水质都达到了生活生产用水水质标准。3种不同填料的组合浮床中,净化效果最好的是球形填料与框架结构组合,在低水力负荷率条件下,该系统对TP、NH4+-N、NO3--N和CODMn的去除率分别达到74.3%、76.6%、63.6%和67.5%。Artificial floating bed technology is an economic and efficient way to control eutrophication. Three kinds of carriers, two kinds of floating bed structure and two kinds of hydraulic loading were used to combine a pilot test system of artificial floating beds, and the purification efficiency of polluted river water surrounding the Taihu Lake in different floating beds was investigated. The results show that the artificial floating beds combined with carriers are effective ways to remedy eutrophic river water by controlling external pollution, and the river water purified by floating beds combined with three carriers meets the water standards for living and production. The frame structure floating bed combined with spherical carrier has the best purification efficiency. In low hydraulic load conditions, the removal rates of TP, NH4 - N, NO3- N and CODMn in the frame structure floating bed combined with spherical carrier are 74.3%, 76.6%, 63.6% and 67.5% respectively.
