摘要:针对好氧颗粒污泥SBR-膜生物反应器(AGS-MBR)组合工艺存在的启动时间长、总磷(TP)去除效果不稳定等问题,以模拟城市生活污水为原水,分别对SBR内的空气流速、MBR的HRT与气水比等运行参数进行优化,实现组合工艺的稳定运行目标。结果表明:优化后的SBR内的空气流速为2 cm·s-1、MBR的HRT为3 h、MBR的气水比为25∶1;AGS-MBR组合工艺出水COD、NH4+-N、TN、TP的平均浓度分别为21.2、0.08、7.8、0.4 mg·L-1;出水C、N、P指标均达到《城镇污水处理厂污染物排放标准》(GB 18918-2002)的一级A标准。该研究可为AGS-MBR组合工艺应用于城市污水处理厂的提标改造提供技术支持。

Abstract:Due to the long start-up time and unstable total phosphorus (TP) treatment efficiency for the aerobic granular sludge SBR-MBR (AGS-MBR) combined process, the operation condition parameters, i.e. the air velocity in SBR, hydraulic retention time (HRT) and gas/water ratio in MBR were optimized in this study to realize the stable performance of AGS-MBR when treating synthetic municipal wastewater. The results show that the optimized operation condition parameters were following: the air velocity of 2 cm·s-1 in SBR, 3 h HRT and the gas/water ratio of 25∶1 in MBR. At these optimum conditions, the average concentrations of COD, NH4+-N, TN and TP in process effluent were 21.2, 0.08, 7.8 and 0.4 mg·L-1, respectively, which meet the first level A standard in GB 18918-2002. This study provides a technique support for upgrading domestic sewage treatment plants with AGS-MBR combined process.
