摘　　要：以西安市兴庆湖为研究对象,研究了基质堵塞对水平潜流人工湿地净化城市湖泊水体的影响。针对利用基质进行过滤,生物量增长和分解,化学物质沉积和沉降时导致孔隙堵塞的问题,提出采用水解酸化预处理、间歇运行、药剂溶菌等方法解决。研究表明,基质堵塞问题的解决,使污水中悬浮物截流去除,可极大地提高后续湿地处理系统正常运行的可靠性。Taking the Xingqing Lake in Xi＇an as the research object,the substrate clogging effects of horizontal subsurface flow constructed wetland to purify the urban lakes were researched by experiment.According to the problem that matrix filter,biomass growth and decomposition,chemical deposition and settlement led to plugging of pores,the paper put forward the method by hydrolysis acidification pretreatment,intermittent operation,agents lysozyme,and so on.The results show that the solution of substrate clogging remove suspended matter in wastewater,and greatly improve the reliability of the normal operation of the wetland treatment system.
