摘要
研制开发了高浓度絮体化好氧颗粒污泥流化床装置，针对生活废水进行了半工业性实验。3个月的连续运行结果表明，高浓度絮体化好氧颗粒污泥流化床具有较高的生物降解效率，且能够稳定运行。实验表明，该装置内MLSS达到14g／L，是AA／O氧化沟（MLSS为3-4g，L）的4倍。其水力停留时间为1h时的出水COD是45mg／L，达到国家排放标准；控制水力停留时间为4h时，出水COD稳定在23m班左右，其处理效率是传统AA／O氧化沟工艺的4倍。
An equipment of highly concentrated flocculating aerobic granular sludge fluidized bed has been studied and developed for carrying out the semi-industrial experiments on domestic sewage. After a 3-month continuous operation,the results show that this equipment has higher biodegradation efficiency and could run stably. The experiment results show that the MLSS in the equipment is up to 14 g/L,which is 4 times of AA/O oxidation ditch （MLSS ：3-4 g/L）. When the hydraulic retention time （HRT） takes one hour, the effluent COD turns out to be 45 mg/L, which meets the requirements of the national discharge standards. When the HRT is 4 h, effluent COD turns out to
