MBR membrane solves the problem of excessive nitrogen and phosphorus in industrial wastewater

Release Date:



With the rapid development of industrialization, the problem of industrial sewage is becoming more and more serious, and the excessive nitrogen and phosphorus has become an urgent problem to be solved. Nitrogen and phosphorus, as the main nutrient elements for plant growth, play an important role in nature, but excessive nitrogen and phosphorus discharged into the water body will lead to eutrophication of the water body, and then cause algae blooms, destroy the water ecological balance, and even affect human health. Therefore, to solve the problem of excessive nitrogen and phosphorus in industrial sewage is of great significance for protecting water environment and maintaining ecological balance.


MBR membrane bioreactor (MBR) technology, as an advanced wastewater treatment technology, has shown unique advantages in solving the problem of excessive nitrogen and phosphorus in industrial wastewater in recent years. MBR membrane technology combines the advantages of biological treatment and membrane separation technology, and can effectively remove nitrogen and phosphorus pollutants in sewage through efficient membrane filtration.

First of all, MBR membrane technology converts organic substances in sewage into inorganic substances through the biological treatment unit and utilizes the metabolic action of microorganisms, while achieving the conversion of nitrogen and phosphorus. In the biological treatment process, microorganisms transform ammonia nitrogen into nitrate through nitrification, denitrification and other reactions, and then reduce nitrate to nitrogen through denitrification, so as to achieve effective removal of nitrogen. At the same time, phosphorus removal is mainly achieved through biological phosphorus removal technology, which utilizes phosphorus absorption and phosphorus release of phosphorus accumulating bacteria under anaerobic and aerobic conditions.

Secondly, MBR membrane technology further improves the removal efficiency of nitrogen and phosphorus through membrane separation unit. MBR membrane has an efficient interception effect, which can effectively intercept microorganisms, colloids, suspended solids in sewage and prevent them from entering the subsequent treatment unit, thus ensuring the stability of effluent water quality. At the same time, MBR membrane can also realize the deep treatment of dissolved pollutants, including dissolved nitrogen and phosphorus, and further improve the removal rate of nitrogen and phosphorus.

In addition, MBR membrane technology also has the advantages of small footprint, high processing efficiency and stable operation. Compared with traditional wastewater treatment processes, MBR membrane technology can achieve efficient wastewater treatment in a smaller space and reduce construction costs. At the same time, due to its high treatment efficiency and stable operation, it can cope with changes in different water quality and water quantity, and meet the various needs of industrial sewage treatment.

However, MBR membrane technology also faces some challenges in the application process, such as membrane pollution, membrane replacement cost and so on. In order to overcome these challenges, it is necessary to continuously optimize the MBR membrane technology, improve the anti-pollution performance of the membrane, extend the service life of the membrane and reduce the operating cost.

In summary, MBR membrane technology has significant advantages in solving the problem of excessive nitrogen and phosphorus in industrial wastewater. Through the combination of biological treatment and membrane separation technology, MBR membrane technology can realize the effective removal of nitrogen and phosphorus pollutants in sewage, providing an efficient and environmentally friendly solution for industrial sewage treatment. With the continuous progress and optimization of technology, MBR membrane technology will play a greater role in the field of industrial sewage treatment, and make important contributions to the protection of water environment and the maintenance of ecological balance.
