| 摘 要： | 针对传统人工湿地负荷低、硝化能力弱和易堵塞的缺点,结合曝气生物滤池与人工湿地强化理论的研究成果,自主开发了人工增氧型复合湿地工艺,即生物接触氧化预处理+微曝气垂直流湿地+水平潜流湿地。通过对滇池北岸城郊混合制污水处理的模型试验,分析该工艺流程各净化单元的污染物去除效果。结果显示,人工增氧型复合湿地对不同水力负荷和污染负荷都体现了较强的缓冲调节能力和较高的净化效果。对污染物的总去除率分别为SS 94.5%、CODCr71.3%、氨氮72.3%,在进水总氮10.0 mg.L-1条件下实现了41.9%的总氮去除率,出水总氮均值为5.8 mg.L-1。 |

| Abstract: | Combining the research theory of biological aerated filter and constructed wetland,a new technology of artificially aerated integrated constructed wetland is developed to avoid such shortcomings of the traditional constructed wetland as low hydraulic loading,weak nitration capacity and easy clogging.This technology combines the processes of pre-treatment of bio-contact oxidation,artificially aerated vertical flow wetland and horizontal subsurface-flow wetland.This technology demonstrated excellent efficienc... |
