摘 要: | 利用正交实验确定反应器的最佳运行参数,研究螺旋流气提式内循环反应器对COD、氨氮、SS等污染物的去除效能。结果表明:反应器最佳运行参数为HRT(水力停留时间)10h、QL(曝气量)0.55m3/h、SRT(泥龄)5d,该工况下反应器出水COD、NH4+-N和SS的去除率分别为90.17%、91.45%和91.85%,对TN、TP的去除率一般,分别为55.61%和57.72%,出水水质符合《城镇污水处理厂污染物排放标准》(GB18918-2002)二级标准。

Abstract: | Make use of a quadrature experiment to recognize a responder of the best run-time parameter,search responder's capability to clean pollutants,such as COD,ammonia nitrogen and SS etc.The result is: the responder's best run-time parameter is HRT(hydraulic power staying time)10h,the QL(Aeration)0.55m3/h,SRT(mire age)5d,under the condition of work,the responder's clean rate are: water COD is 90.17%NH4+-N is 91.45%,SS is 91.85%.The rate for cleaning TN and TP is general,they are 55.61% and 57.72%,the water fluid matter matches《town wastewater treatment,plant pollutant exhaustion standard》(GB18918-2002).This is the second class standard. |
