The principle of the MBBR process is to increase the biomass and biological species in the reactor by adding a certain number of suspension carriers to the reactor, thus improving the efficiency of the reactor.Because the density of packing is close to that of water, it is completely mixed with water when aerated, and the environment of microorganism growth is gas, liquid and solid three phases. The collision and shearing action of the carrier in water make the air bubble smaller and increase the utilization rate of oxygen. In addition, each carrier has a variety of biological species inside and outside, the internal growth of some anaerobes or facultative bacteria, the outside is a good culture, so each carrier is a micro reactor, which makes the nitrification reaction and denitrification at the same time, thus improving the treatment effect.
The process is applicable to high-contaminated wastewater such as meat processing wastewater, high-concentration organic wastewater, landfill leachate, etc. Meanwhile, for domestic sewage with low organic matter concentration, all water quality indexes of treated effluent can reach the national reuse index.
We can design best process according to wastewater type,wastewater quality and effluent standards,too.
Advantages:
1. Impact load, long sludge age, less residual sludge, high efficiency and flexible operation.
2. The sludge concentration in the reactor is relatively high. Generally, the sludge concentration is 5 to 10 times that of the conventional activated sludge process, and the aeration tank sludge mass concentration can be as high as 30 to 40 g/L.
3. Head loss is small, should not be blocked, no backwash, generally do not return.
4. As the core of the MBBR process, the suspended filler has aerobic and anaerobic metabolic activity, and can be a good nitrogen and phosphorus removal.
Application scope:
1. Hotels, restaurants, nursing homes, hospitals.
2. Residential areas, village, town.
3. Stations, airports, port terminals and ship.
4. Factories, mines tourist, scenic.
5. All kinds of industrial wastewater similar with domestic sewage
