摘　　要：在集中式污水处理技术的使用受到限制的地区,生物造粒流化床作为一种短流程分散式污水处理技术得到了应用。经过对中试生物造粒流化床出水水质的长期监测,结果显示其出水水质良好,对SS、COD、TP、NH3-N、TN的平均去除率分别达到了86%、89%、88%、63%、44%。生物造粒流化床在绿地世纪城居住小区和陕鼓动力股份有限公司被成功应用于处理生活污水和生产废水,后续工艺的再生水可用于补充景观湖水、浇洒道路和草坪,其总运行成本分别为0.89和1.01元/m3。As a short-cut distributed technology for wastewater treatment, the fluidized-pellet-bed （FPB） bioreactor finds application in some areas where the usage of centralized wastewater treatment technology is restricted. The results of long-term monitoring of effluent quality of a pilot-scale FPB biore- actor showed that the effluent quality was good. The average removal rates of SS, COD, TP, NH3 - N and TN were 86%, 89%, 88%, 63% and 44%, respectively. The FPB bioreactor was successfully ap- plied in the Lyudi residential community and the Shaangu Power Co. Ltd. for domestic and industrial wastewater treatment. The post-FPB bioreactor effluent could be used for landscape water supplement, road watering and gardening. The whole operation costs for Lyudi and Shaangu were 0.89 yuan/m3 and 1.01 yuan/m3, respectively.
