Advantages and disadvantages of MBBR sewage treatment plant

Advantages of MBBR sewage treatment plant: Buried below the surface, the surface above the equipment can be used for greening or other purposes, without the need for building, heating and insulation. The two-stage biological contact oxidation process adopts plug-flow biological contact oxidation, and its treatment effect is better than that of full-mix or two-stage series-connected full-mix biological contact oxidation tanks.

Compared with the activated sludge tank, it has the advantages of small volume, strong water quality adaptability, strong shock load resistance, stable effluent quality, and no sludge bulking. The pond adopts a new type of elastic three-dimensional filler, which has a large specific surface area, and the microorganisms are easy to form a film and release. Under the same organic load condition, the removal rate of organic matter is higher, which can improve the solubility of oxygen in water in air.

The biochemical pool adopts the biological contact oxidation method. The volume load of the filler is relatively low, the microorganisms are in the stage of self-oxidation, and the sludge yield is small. It only takes more than three months (90 days) to discharge the sludge (pump or dewater it into a mud cake for transportation).

The deodorization method of MBBR sewage treatment plant is not only conventional high-altitude exhaust, but also equipped with soil deodorization measures. The whole equipment processing system is equipped with automatic electrical control system and equipment failure alarm system, which is safe and reliable in operation. Usually do not need special personnel to manage, only need to maintain and maintain the equipment in time.

Disadvantages of MBBR sewage treatment plant: not conducive to maintenance. After the equipment fails, it is inconvenient to maintain and replace. This is usually the thing that owners hate the most. Adaptability to the environment, antifreeze in winter and flood control in summer. The north needs deep burial isolation.

Applicable conditions of MBBR sewage treatment plant: less water, low pollutant concentration, simple composition, limited space, and beautifying the surrounding environment. In the above situation, it is generally recommended to use a buried integrated sewage treatment equipment system for treatment.
