摘要：通过构建表流与潜流湿地相结合的复合人工湿地来处理水禽污染的富营养化水体,研究了运行2年的复合人工湿地对化学需氧量(CODcr)、总悬浮物(TSS)、全氮(TN)和全磷(TP)的去除作用。研究表明,复合人工湿地对CODcr、TSS、TN和TP的2年平均去除率分别为42.64%、72.64%、31.69%和52.67%;对污染物CODcr、TSS、TN、TP的去除效果随复合人工湿地运行时间变化而有所差异。在表流湿地中,夏季对CODcr的平均去除率要优于秋季,秋季潜流湿地和复合人工湿地对CODcr的平均去除率优于夏季。在对TSS的平均去除率,表流湿地、潜流湿地和复合人工湿地都表现为秋季优于夏季。表流湿地对TN的平均去除率表现为夏季显著优于秋季。在对TP的平均去除率中,表流湿地和复合人工湿地都表现为秋季优于夏季,而潜流湿地对TP的去除效果表现为秋季低于夏季。通过对进出水中的TP、TN、TSS和CODcr进行回归分析发现,除复合人工湿地和表流湿地区TSS的进水质量浓度与出水质量浓度无明显相关性外,其他复合人工湿地不同构建类型进出水的CODcr、TN、TP质量浓度均存在显著线性相关关系。该研究可为我国北方地区应用复合人工湿地处理富营养化水体提供理论依据。
A integrated artificial wetland was constructed by surface and subsurface wetland to dispose the effect of eutrophication caused by waterfowl. The removal efficiencies of chemical oxygen demand （CODcr）, total suspended solids（TSS）, total nitrogen（TN） and total phosphorus（TP） in the integrated artificial wetland which had running for 2 years have been studied. The results showed that the average removal rates of CODcr, TSS, TN and TP were 42.64%, 72.64%, 31.69% and 52.67%, respectively and the removal rates varied with the runtime. The analysis for seasonal effects of summer and autumn showed that, the average removal rate of CODcr in summer was higher than that in autumn for surface wetland, while in both subsurface and integrated wetlands, the seasonal tendencies were reverse. For disposing TSS, in surface, subsurface and combined constructed wetlands, the autumn outperformed the summer. The average removal rate of TN in the summer was higher than that in the autumn for surface wetland. For TP average removal, the performance of the autumn was better than the summer’s in both surface and integrated artificial wetlands, but less efficient than summer’s in subsurface wetland. The relationships of CODcr, TSS, TN and TP concentrations between the influent and effluent were different in integrated artificial wetland. There was no clear relationships between the influent and effluent concentrations of TSS in both subsurface and integrated artificial wetlands. Moreover, the influent and effluent concentrations of CODcr, TP and TN had significant linear correlation in different types of integrated constructed wetlands. The results of this study could provide scientific support for the application of integrated constructed wetlands in treating the eutrophic water in northern China.
