农村生活污水生物膜反应器的研究进展

农村生活污水治理助力乡村振兴建设,目前基于已有的污水处理技术,研发了一系列农村生活污水一体化设备并广泛投入农村污水治理项目中。针对分散农村生活污水,生物膜反应器更是被普遍应用。这些设备的工艺大体一致但其处理效果参差不齐,主要原因归根结底是由于生物膜反应器内部填料处理差异所致。基于此,就已有农村生活污水处理生物膜反应器及其内部典型填料特点、结构和性能进行简要概述,旨在为农村生活污水处理新技术和一体化设备研发提供指导。

Research progress of biofilm reactor for rural domestic sewage treatment

The treatment of rural domestic sewage helps rural revitalization construction.Presently,a series of rural domestic sewage integration equipment has been developed and widely put into rural sewage treatment projects based on the existing sewage treatment technologies.Biofilm reactor is widely used in the treatment of disperse rural domestic sewage.Unfortunately,the treatment effect is uneven although the producing processes of these devices are basically the same,which is mainly due to the difference of packing fillers inside the biofilm reactor.Therefore,this paper gave a brief overview of the characteristics,structure and performance of the existing biofilm reactor for rural domestic sewage treatment and its internal typical fillers,thus providing guidance for the research and development of new technologies and integrated equipment for rural domestic sewage treatment.
