- Abstract:
- For municipal sewage treatment, aiming at the challenges of less land for sewage treatment, high discharge standards, and uncontrollable stability in China, the Moving Bed Biofilm Reactor (MBBR) process shows the advantages of land saving, high efficiency, flexibility and stability, which has achieved good practical effects. The application scale has reached 2 500× 104 m3/d in China. According to the main mode of existence of microorganisms, MBBR process is divided into integrated fixed-film activated sludge (IFAS) and pure MBBR, which belong to activated sludge process and biofilm process, respectively. At the same time, the pure MBBR coupled with magnetic coagulation precipitation has formed BFM (Biofilm & Magnetic) process with nitrogen and phosphorus removal function. Since the sewage quality is complex and sewage types are varied, a series of solutions for the application of MBBR process to municipal sewage treatment have been formed. For the solutions of the IFAS original biochemical pool, the reconstruction could increase the sewage treatment capacity within 30%-50% of the original tank treatment standard. The BFM process in-situ reconstruction could increase the sewage treatment capacity by more than twice of the original tank standard. The new-built BFM process for deep nitrogen and phosphorus removal achieves the quasi-Ⅳ class of surface water quality standard and even higher discharge standards. The new-built BFM process with side treatment facilities increase the sewage treatment capacity of the whole plant. For each process, the advantages, application scenarios and practical application effects are discussed, and four technical routes are further proposed for the reconstruction of the original biochemical pool of IFAS. The MBBR process can effectively solve the needs of new-built, reconstruction and expansion of various WWTPs. Especially, the BFM process based on pure membrane MBBR occupies less land, showing the characteristics of rapid implementation and flexible layout with assembly construction. By loading the intelligent water optimal control cloud platform, the management upgrading, energy conservation and consumption reduction of WWTP operation can be realized. The BFM process is suitable for comprehensive treatment scenarios, such as municipal sewage treatment, industrial wastewater treatment, black and odorous water body treatment, initial runoff treatment and rural sewage treatment. Focusing on the development of green and low-carbon sewage treatment technologies, the realization of MBBR-based Anammox process with suspended carriers as the matrix is the development direction of BFM process in future.
