颗粒型生物膜反应器在污水处理中的应用

Applications of Particulate Biofilm Reactors in Wastewater Treatment

介绍了颗粒型生物膜反应器在污水处理中的应用情况,对比了不同反应器结构和技术特点。与传统的活性污泥法和静态生物膜反应器相比,颗粒型生物膜反应器具有沉降速度快、污泥浓度高、比表面积大等特点,可以达到很高的负荷,节省占地面积。另外,颗粒型生物膜反应器的污泥产率也非常低、不存在污泥膨胀的问题,日常维护也非常简单。并指出随着对该领域进一步的深入研究和新型反应器的开发,颗粒型生物膜反应器将得到更为广泛的应用。

Application of particulate biofilm reactors in wastewater treatment was introduced, configurations and technical Characteristics of different reactors were contrasted. In compared with activated sludge and static biofilm, particulate biofilm reactors have the characteristics of rapid setting velocity; high biomass concentration and high surface area that resulted in high conversion capacities and small area requirements. Furthermore, sludge production of particulate biofilm reactors is very low, and there are no problems of bulk sludge, so the maintainment of running is very simple. As the development of particulate biofilm technology and novel reactors, the particulate biofilm reactors must be widespread used.
