摘　　要：采用自主设计的智能控制SBBR污水处理装置,利用聚乙烯（PE）载体,考察了水力停留时间（HRT）对智能控制SBBR污水处理装置的脱氮效能影响,得出了最佳工艺运行参数。试验在温度为25℃,好氧溶氧DO控制在1.5~2.5时,考察了HRT分别为4h、6h、8h、10h、12h时的脱氮效能。结果表明：当HRT为8h时,系统的脱氮效率最高,COD去除率为91.26%,氨氮的去除率为80.68%,总氮的去除率为70.58%,所以从能耗和处理效果角度看,当水力停留时间为8h时,系统运行最为高效。Using independent design of the intelligent control of SBBR sewage treatment plant Wlttl the polyetilylene （PE） carrier, wetested theinfluenceof hydraulic retention time （HRT） ondenitrification effieiencyof intelligent con- trolled SBBRsewage treatment plant, and optimum operating parameters were obtained. The test was underthe tem- perature of 25 ℃, aerobic dissolved oxygen DO control in 1.5 ~ 1.5, HRT, respectively 4 h, 6 h, 8 h, 10 h, 12 h denitrifieation efficiency.Results showed that when HRT was 8 h, the system had the highest nitrogen efficiency, COD removal rate of 91.26 %, as the removal rate of ammonia nitrogen was 80.68 %, with total nitrogen removal rate of 70.58%.In conclusion, when the hydraulic retention time was 8 h, the system had higher nitrogen removal efficiency.
