螺旋流气提式内循环反应器处理污水的试验研究

摘要

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.%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。
