摘要(Abstract):
以新型间歇增氧垂直流人工湿地系统为研究对象,采用中心复合设计响应曲面法优化垂直流人工湿地脱氮处理过程中曝气工艺参数并预测其脱氮效能。以曝气量、曝停比、曝停周期为间歇曝气影响因素,分别以人工湿地氨氮去除率和总氮去除率为响应值建立垂直流人工湿地氨氮去除率和总氮去除率的二次回归模型,通过假设检验(F-test),模型均非常显著且具有较好的相关性。间歇增氧垂直流人工湿地脱氮处理中曝气量、曝停比为对氨氮去除影响极显著的曝气参数,通过影响因子主次分析,曝气量、曝停比、曝停周期对氨氮去除率的影响顺序是:曝停比>曝气量>曝停周期;曝停周期为对总氮去除具有极显著影响的曝气参数,通过影响因子主次分析,曝气量、曝停比、曝停周期对TN去除率的影响顺序是:曝停周期>曝气量>曝停比。模型预测氨氮与总氮去除率的最佳曝气参数分别为:曝气量2 m~3/h、曝停比0.25、曝停周期12 h、曝气量2 m~3/h、曝停比0.25、曝停周期6 h;氨氮、总氮去除率预测值分别为98.4%、83.2%,预测值与实测值吻合。响应曲面法用于优化曝气参数对人工湿地脱氮效能影响具有可行性,可实现间歇增氧人工湿地脱氮效能的准确预测。
