| 摘 要： | 人工湿地可应用于城市污水厂出水深度处理和农业污染治理,但反硝化碳源不足问题制约了其脱氮能力.本试验利用树皮作为垂直流人工湿地强化反硝化脱氮填料,分析了水力负荷、硝酸盐负荷以及pH对人工湿地脱氮效果的影响.结果表明,人工湿地可以达到预期的反硝化水平,反硝化速率随水力负荷、硝酸盐负荷的增加而增大,去除率随两者的增加而减小,...

| Abstract: | Constructed wetlands have been widely used for the treatment of outlets of municipal wastewater treatment plants,treatment of agricultural pollution etc,adequate carbon is a very good source for denitrification and it is very crucial for improving the removal rate of nitrate nitrogen in constructed wetlands.An attempt has been made to workout for the nitrate removal by the integrated vertical constructed wetland,the bark was used for carbon source,the results shows the denitrifying bacteria in the construct... |
