缺氧-厌氧-好氧工艺处理城市污水

摘要以缺氧、厌氧及好氧工段单元试验研究为基础,以城市污水为研究对象,将传统A2/O工艺厌氧/缺氧工段倒置,取消内回流,进行生物脱氮除磷的研究。考察了最佳工艺条件下,本工艺对城市污水中氮、磷及COD等污染物的去除状况。相对于A2/O工艺,本工艺的运行费用大大降低。从系统运行状况来看,经处理后的城市污水,其出水氮、磷及COD指标达到国家城市污水处理厂污染物排放标准(GB 18918-2002)一级标准,为更大规模的试验提供了基本的试验数据。

Abstract： Based on the separate research on anoxic and anaerobic and aerobic process for biological nitrogen and phosphorus removal of municipal wastewater,a reversed traditional A~2/O(anaerobic/anoxic/oxic) process without inner circumfluence was developed.The experiment on removing nitrogen and phosphorus compounds was carried out under the best conditions.The results showed that the cost of the proposed process was less than that of A~2/O process and the effluent nitrogen,phosphorus and COD concentrations could meet with the first-grade discharge standard of pollutants for municipal waster treatment plant(GB 18918-2002).These can offer primary conditions for more sweeping experiment.
