中文摘要：

介绍了井式AAOO新型工艺，并考察了pH值、DO、TOC、TN、TP、NH4＋-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》（GB18918-2002）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。

英文摘要：

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.
