Abstract:

In order to solve clogging problems of constructed wetland substrates,a new program on a new type of composite constructed wetland substrates has been proposed. The treatment effects of the new type of composite pro-gram and traditional single program on various pollutants,effective porosity,head loss,clogging time,etc. are studied mainly. Meanwhile,the clogging situations of substrates of the new type of composite program and traditional single program at the same depth are analyzed. The test results show that regarding the treatment effects of pollutants,effec-tive porosity,head loss,clogging time,etc.,the new type of composite constructed wetland substrates program is superior to the single traditional program.

Key words: constructed wetland, new type of composite, porosity, clogging, head loss

摘要：

为了解决人工湿地基质堵塞问题,提出了新型复合人工湿地基质方案,主要研究了新型复合方案和传统单一方案对各种污染物的处理效果、有效孔隙率、水头损失和堵塞时间等内容,同时分析了新型复合方案与传统单一方案在同一深度处的基质堵塞情况。试验结果表明,在污染物的处理效果、有效孔隙率、水头损失和堵塞时间等方面,新型复合人工湿地基质方案均优于传统单一方案。
