摘　　要：将微絮凝过滤前处理和人工湿地防堵塞结构构成的防堵塞体系应用于某会议中心富营养化景观水体水质生态修复工程,研究了其对人工湿地防堵塞性能的影响。结果表明:防堵塞体系对于预防湿地堵塞具有显著效果。经微絮凝过滤和配水渠过滤系统处理后,湿地进水端具有较低的SS和Chl-a浓度。基质的材料和构成对湿地水力坡度的影响较为明显,优化湿地基质的种类和级配对于预防湿地堵塞具有积极作用。An anti-clogging system including pretreatment of micro-flocculation and anti-clogging structure of constructed wetland was applied in the eco-remediation project of eutrophicated landscape water in a conference center. The effects of the anti-clogging system on the anti-clogging performance of constructed wetlands were studied. The results showed that the anti-clogging system had significant effects on the substrate clogging prevention. After miero-floceulation pretreatment and filtration by the distribution channel, concentrations of suspended substance （SS） and Chlorophyll-a （Chl-a） were both quite low at the inlet of the constructed wetlands. Materials and compositions of substrates had a close relation with changes in hydraulic gradient values, which indicated that optimum aggregate grading and kinds of fillers played a positive role in anti-clogging of constructed wetlands.
