摘要:
在垂直流潜流式人工湿地中引入赤子爱胜蚓,构建了蚯蚓垂直流潜流式人工湿地.比较了蚯蚓人工湿地与对照人工湿地表层和底层的细菌总数、氨化细菌数、硝化与反硝化细菌数及脲酶活性,分析了蚯蚓的引入对垂直流人工湿地基质中微生物量及脲酶活性分布的影响.结果表明,蚯蚓的引入对微生物的生长与增殖及脲酶活性的提高有明显促进作用.在蚯蚓主要活动的表层0~20cm基质内,蚯蚓人工湿地的细菌总数、氨化细菌数、硝化细菌数分别达到0.86×109~3.78×109cells/g,1.01×107~5.75×107MPN/g和1.88×108~6.08×108cells/g,显著高于对照人工湿地; 同时,蚯蚓人工湿地表层的脲酶活性也明显提高; 蚯蚓的引入提高了有机污染物及氮的转化与去除的速率.
Abstract:
A vertical flow constructed wetland was built by adding Eisenia foetida. The total bacterial count in the surface and bottom layer, urease activity, as well as the numbers of ammonification, nitrification and denitrification bacteria in the Eisenia foetida constructed wetland and the control constructed wetland were compared. Also the effect of adding Eisenia foetida on biomass and urease activity in each layer of the vertical flow constructed wetland were analyzed. The results show that adding Eisenia foetida remarkably promotes the growth of microorganisms and improves the urease activity. In the surface layer(0~20cm)where the Eisenia foetida mainly functions, the total bacterial count, the ammonification and nitrification bacteria count in the Eisenia foetida constructed wetland are 0.86×109 to 3.78×109cells/g, 1.01×107 to 5.75×107MPN/g and 1.88×108 to 6.08×108cells/g, respectively, which are significantly higher than in the control constructed wetlands. Meanwhile, the urease activity in the surface layer of the Eisenia foetida constructed wetland is also improved remarkably, and the transformation and removal rates of organic pollutants and nitrogen are also enhanced by adding Eisenia foetida.
