摘　　要：介绍了井式AAOO新型工艺,并考察了pH值、DO、TOC、TN、TP、NH+4-N等指标的沿程变化情况,结合理论分析研究该工艺开发的合理性。结果表明,pH值在厌氧区有所下降,在缺氧区逐渐上升;厌氧区对TOC的去除率最高,去除量占到总去除量的70%;运行至第10、20、30天时,对TP的去除率分别为65%、88%、86%,对TN的去除率分别为71%、68%、79%,出水TN浓度满足《城镇污水处理厂污染物排放标准》(GB 18918—2002)中的一级A标准。该新型工艺结合了AAOO和深井曝气工艺的优点,发挥了耐水力冲击和有机负荷冲击的能力,同时温度稳定,适用地区广泛,产生气味小且便于收集,具有较大的应用价值。A new well-type AAOO process was introduced, the variations of pH, DO, TOC, TN, TP and NH4 ＋- N in each section were investigated, and the rationality for developing the process was studied by theoretical analysis. The pH declined gradually in the anaerobic zone and increased in the an- oxic zone. 70% of TOC removal occurred in the anaerobic zone. The removal rates of TP and TN were 65% , 88%, 86%, and 71%, 68%, 79%, respectively at 10 d, 20 d and 30 d. The effluent quality met the first level A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treat- ment Plant （GB 18918 -2002）. The new process combined the advantages of AAOO and deep well aer- ation process, it displayed high resistance to hydraulic and organic shock loads, stable temperature, high applicability and low odor, with great value for application.
