- Abstract:
- The construction of advanced treatment facilities to enhance the treatment of secondary biological tailwater is common in upgrading and renovating wastewater treatment plants. This study presents an overview of the development of the biofilm & magnetic separation (BFM) process with the moving bed biofilm reactor (MBBR) pure biofilm methodology as the core. It reviews the engineering applications of the BFM process in upgrading of municipal tail water treatment. In comparison with denitrification deep bed filter (DNF) and biological aeration filter (BAF) process, the construction configuration and land utilization, operation efficacy, investment costs and operational expenses of BFM process are analyzed. The BFM process demonstrates low influent water quality requirements, facilitates efficient nitrogen and phosphorus removal, ensures stable operation, exhibits robust resistance to hydraulic and organic shock loads, offers the potential for future performance enhancements, and operates in an economical and efficient manner, thereby providing a novel solution for the upgrading of municipal tailwater treatment. During implementation, critical factors including the energy consumption associated with suspended carrier fluidization, carrier agitators, interception systems, and biofilm-water separation should be given particular-attention to guarantee the safe and reliable functioning of the process.
