摘　　要：堵塞已成为限制人工湿地健康长久运行的关键问题。应用AHP-FCE法构建了垂直潜流人工湿地堵塞影响因素综合评价体系,从水质特征、工艺参数、管理措施和环境条件4个方面共选取了17个评价指标,并划分了湿地堵塞指标评价标准。以容城人工湿地为研究案例,结果表明:容城湿地的堵塞评价结果为“良”,具有较好抗堵塞能力,其中,固体悬浮物、布水集水方式及植物管理等指标在抗堵塞方面处于较优水平,可根据进水水量水质变化适当增加间歇运行频次、减小水力负荷或增设预处理措施等方式来降低湿地堵塞风险。评价结果反映了湿地堵塞风险情况,可为缓解堵塞问题提供参考。Clogging had become a key problem that limits the healthy and long-term operation of constructed wetlands.The AHP-FCE method was used to construct a comprehensive evaluation system for the influencing factors of vertical subsurface flow in constructed wetland clogging.A total of 17 evaluation indicators were selected from four aspects:water quality characteristics,process parameters,management measures and environmental conditions,and the evaluation criteria of wetland clogging were defined.As a case study,the clogging evaluation of the Rongcheng wetland showed a'good'status with a strong anti-clogging ability.Among them,solid suspended solids,water distribution and water collection methods,and plant management were at a better level in anti-clogging.The risk of wetland clogging can be reduced by appropriately increasing the frequency of intermittent operation,reducing hydraulic load or adding pretreatment measures according to the change of wastewater quality.The evaluation results reflected the risk of wetland clogging and provide a reference for alleviating clogging problems.
