摘要
采用厌氧水解-二段生物接触氧化法,小试研究了城市生活污水的处理效果及HRT、DO含量、容积负荷对污染物去除率的影响。结果表明,室温下,当HRT为6 h、氧化池内DO的质量浓度为5～6 mg/L时,对COD、SS、NH4+-N去除率分别达到80%、90%、99%,出水水质达到GB 18918-2002一级A排放要求。
In this paper, anaerobic hydrolysis-binary biological contact oxidation was used to treat the urban sewage. The effects of hydraulic retention time, dissolved oxygen concentration, volume load on the pollutants removal rate were investigated. Test results show that when HRT is 6 h and DO is 5-6 mg/L, the removal rate of COD, SS and NH3-N are 80%, 90%, 99%, respectively. Effluent water quality could meet the level A of discharging standard for GB 18918-2002.
