摘　　要：通过考察脉冲式SBR法处理城镇生活污水时有机物降解、硝化和反硝化反应中DO、氧化还原电位（ORP）及pH的变化规律,建立了这些控制参数与有机物去除、硝化与反硝化反应过程中主要污染物指标间的相关关系。在此基础上,建立脉冲式SBR法深度脱氮的模糊控制系统,更加有效地控制脉冲式SBR法多段进水的运行方式,达到深度脱氮的目的,并尽可能降低运行成本。当进水COD在130.0～243.6 mg/L、NH4^＋-N在55.98～76.40 mg/L时,在原水中反硝化碳源充足情况下,脉冲式SBR法反硝化结束时最终出水COD低于40 mg/L,NH＋4-N低于1.0 mg/L,TN低于3.0 mg/L。In this paper, pulsed SBR were employed to treat the municipal sewage. The correlation for some process parameters such as DO,ORP and pH value during the removal of organic matters and nitrification and denitrification process were checked and established. Based on the relationship between the process parameters and the treatment process,the fuzzy control system was designed to control the several steps feeding in the pulsed SBR effectively. It was found that the quality of the effluent could meet the discharge standard using this system with low operation costs and the high removal efficiency. The results showed that while the pulsed denitrification process with rich carbon was over,COD,NH4^＋-N and TN in the water outlet were less than 40,1.0,3.0 mg/L respectively under the conditions of 130.0～243.6 mg/ L for COD and 55.98～76.40 mg/L for NH4^＋-N.
