| 摘 要： | 试验以实验室自配的污水模拟小城镇生活污水,基于悬挂填料AmOn一体化反应器,通过调节蠕动泵转速和气体流量计考察水力停留时间和曝气量对COD(Cr)、NH4+-N、TN、TP去除率的影响。试验结果显示,当HRT=14h时,各污染物去除率分别为89.15%、99.02%、48.59%、32.47%;当曝气量为600 L/h,为89.87%、99.74%、81.3%、35.04%。最终采用层次分析法,从污染物去除效率、处理效率、运行成本三个角度进行综合评价,得出水力停留时间14h、曝气量600L/h的工况为试验的最优工况。

| Abstract: | In this experiment,domestic sewage from small towns was simulated by sewage self-made in laboratory.Based on the AmOn integrated reactor with suspending filler,the effects of HRT and aeration rate on the removal rate of CODCr、NH4+-N、TN、TP were investigated by adjusting the speed of peristaltic pump and gas flowmeter.The results of the test show that the removal rates of each pollutant were 89.15%,99.02%,48.59%and 32.47%respectively when HRT=14h was used,and it was 89.87%,99.74%,81.3%and 35.04%respectively when the aeration rate was 600 L/h.Finally,AHP was used to comprehensively evaluate the removal efficiency,treatment efficiency and operating cost of pollutants.It was concluded that HRT 14h and aeration 600 L/h were the optimal conditions of the test. |
