摘　　要：为了解组合运行方式对一体化活性污泥工艺处理效果的影响,对3池组合运行方式和5池组合运行方式进行对比试验。结果表明,5池组合运行方式在进水搅拌过程反硝化完全,可以出现良好的厌氧释磷状态,整体除磷效果好;3池组合运行方式由于曝气历程较长,进水搅拌过程中反硝化不彻底,难以出现厌氧释磷状态,除磷效果较差。试验结果表明,3池交替工艺运行过程中难以有效除磷脱氮,通过增加分格设置和运行方式交替可以有效提高除磷脱氮效果。Contrast tests were done with three tanks and five tanks integration modes to investigate their influence on removal efficiency of integrated activated sludge system. Results indicated five tanks integration mode could get complete denitrification and favorable anaerobic phosphorus releu~ dur- ing filling phase. Its phosphorus removal efficiency was high. However, in three tanks integration mode danitrification was incomplete and phosphorus release did not arise during filling phase owing to long time aeration. Its phosphorus removal efficiency was low. The results implied three tanks alteraation system could not remove phosphorus and nitrogen efficiently. Phosphorus and nitrogen removal efficiency could be improved by comtmentation addition and running mode alternation.
