摘　　要：结合前置反硝化工艺研究缺氧一好氧两级BIOSTYR模型反应器处理生活污水的效能。采用对缺氧段反应器好氧预挂膜的两阶段复合式自然挂膜方法进行缺氧～好氧两级BIOSTYR模型反应器的挂膜启动。结果表明：（1）缺氧好氧两级BIOSTYR模型反应器对COD、NH3-N、TN和TP总去除率平均分别达到91.9％、90．5％、55．1％和45．7％，出水ss较原水有所升高，但其为反冲洗周期的延长作出了积极的贡献。（2）单体反应器中，缺氧段对COD、NH3N、TN、TP的平均去除率分别为71．6％、52．3％、45．8％、32．9％，好氧段对COD、NH3-N、TN、TP的平均去除率分别为71．3％、81．6％、17．2％、18．9％。（3）采用脉冲式反冲洗，反冲洗后2～3h恢复正常处理效果。The performance of pre-denitrification combined anoxic oxic two stage BIOSTYR reactor for munici pal sewage treatment was researched in this paper. The anoxic-oxic two stage BIOSTYR model reactor was started up by using two phase composite natural inoculation process, during which the aerobic precoating of bio-film was performed in anoxic reactor. The test results manifested that the average COD, NHa N,TN and TP removal rate of anox- ic-oxic two stages BIOSTYR model reactor was 91.9% ,90.5G ,55.1G and 45.7% respectively. Although the efflu ent SS increased a little comparing with influent SS,it made a positive contribute to the extension of backwashing cy cle. In the monomer reactor, the average COD, NH3-N, TN and TP removal rate of anoxic process was 71. 6%, 52.3 % ,45.8% ,32.9%, and in aerobic process they were 71.3%, 81. 6G, 17.2%, 18. 9G, respectively. The BIO- STYR model reactor could resume normal processing performance after 2-3 h of pulsed backwash.
