摘　　要：依托原污水处理厂Orbal氧化沟工艺,采用PTN微生物强化技术,同时辅以必要的化学强化除磷措施,强化污泥在好氧、缺氧和厌氧3个交替环境中的脱氮效率,实现在不增加后续构筑物的情况下,完成污水处理厂的一级A提标改造:氨氮<5 mg/L,总氮<15 mg/L;出水COD稳定在50 mg/L以下。Basing on Orbal oxidation ditch technology of the original sewage treatment plant, adoptting PTN microbial enhanced technology, meanwhile using necessary chemically enhanced P removal measures, nitrogen removal efficiency in aerobic, anoxic and anaerobic alternating environment strengthens sludge, with increasing subsequent structures, the first grade A transformation of sewage treatment plant is finished： ammonia nitrogen〈5 mg/L, total nitrogen〈15 mg/L;Effluent COD is stable under 50 mg/L.
