- Abstract:
- There is no secondary sedimentation tank and sludge return system in the pure MBBR process.The pollutants can be removed effectively by biofilm which attached to the suspended carriers. The biofilm can be dynamically renewed by fluidization without backwashing. The pure MBBR process has excellent advantages, such as low temperature resistance, high removal loading, short retention time, flexibility application to the many sections of WWTP, so as to obtain excellent effluent quality. In this paper, the characteristics of removal pollutants in pure MBBR process are summarized, and the decarbonization, nitrification and denitrification processes are described as well. The design and application of pure MBBR process in Lillehammer WWTP, Gardermoen WWTP, Sjolunda WWTP, Phillips Petroleum Borger WWTP, and TAU WWTP which are located abroad are introduced. The application of pure MBBR process in micropolluted water, industrial wastewater, municipal wastewater and high ammonia nitrogen wastewater in China are reviewed. Practical application shows that the pure MBBR process combined with a more compact advanced treatment process can save up to 80% of the land occupation compared with the conventional process. The pure MBBR process has the advantages of high removal loading, short process flow, low land occupation, low investment and simple operation. It is suitable for new construction and expansion of WWTP, and has great development space and wide application prospect.
