The MBBR process is currently a popular process in the field of sewage treatment. For those engaged in sewage treatment, the following is worth knowing:
What is MBBR?
The MBBR process uses the basic principle of the biofilm method. By adding a certain amount of suspended carriers to the reactor, the biomass and biological species in the reactor are increased, thereby improving the treatment efficiency of the reactor. Since the density of the filler is close to that of water, it is completely mixed with water during aeration, and the environment for microbial growth is gas, liquid, and solid three phases.
The collision and shearing effect of the carrier in the water makes the air bubbles smaller and increases the utilization rate of oxygen. In addition, each carrier has different biological species inside and outside, with some anaerobes or facultative bacteria growing inside and aerobic bacteria outside, so that each carrier is a micro-reactor, so that nitrification and denitrification reactions can exist at the same time. , Thereby improving the treatment effect.
