With the acceleration of urbanization, the problem of sewage treatment has attracted more and more attention. As an advanced sewage treatment technology, MBR membrane pool plays an increasingly important role in the field of sewage treatment. This article will introduce the role of MBR membrane pool in detail, in order to provide reference for relevant practitioners.
1. Introduction to MBR membrane pool.
MBR membrane pool, the full name of membrane bioreactor (membrane bioreactor), is a wastewater treatment process that combines biological treatment with membrane separation technology. Through the efficient separation of membrane modules, the suspended solids, bacteria and microorganisms in the sewage are intercepted, so as to achieve the purpose of purifying the sewage. MBR membrane pool has the advantages of compact structure, high treatment efficiency, energy saving and environmental protection, so it has been widely used in urban sewage treatment, industrial wastewater treatment and other fields.
Second, the role of the MBR membrane pool.
1.Suspended solids removal.
Through membrane separation technology, the MBR membrane pool effectively intercepts the suspended solids in the sewage and makes the effluent clear and transparent. Compared with the traditional sedimentation tank, the MBR membrane tank has a higher suspended solids removal rate and more stable effluent quality.
2.Degradation of organic matter.
The bioreactor in the MBR membrane tank contains a large number of microorganisms, which convert the organic matter in the sewage into harmless substances through adsorption and degradation, so as to achieve the purpose of purifying the sewage. At the same time, the MBR membrane pool can also effectively remove nutrients such as ammonia nitrogen and total phosphorus in sewage to prevent eutrophication of water bodies.
3.Bacteria and viruses are removed.
The membrane module in the MBR membrane tank has an efficient interception effect, which can effectively intercept bacteria and viruses in the sewage, so as to achieve the purpose of sterilization and virus control. This effect is particularly important for wastewater treatment, such as hospital wastewater, which contains a large number of bacteria and viruses.
4.Nitrogen and phosphorus removal.
Through reasonable process design and operation management, the MBR membrane pool can realize the function of denitrification and phosphorus removal. By controlling parameters such as oxygen** and sludge age in the reactor, the MBR membrane tank can effectively remove nutrients such as nitrogen and phosphorus from the wastewater, so as to meet the wastewater discharge standard.
5.Reduce energy consumption.
MBR membrane tanks use membrane separation technology, which has lower energy consumption than traditional processes such as sedimentation tanks and filter tanks. At the same time, the MBR membrane tank can also realize the reduction and resource utilization of sludge, thereby further reducing energy consumption.
3. Application prospect of MBR membrane pool.
With the continuous improvement of environmental protection awareness and the continuous innovation of sewage treatment technology, MBR membrane pool has a wide range of application prospects as an efficient and environmentally friendly sewage treatment technology. In the future, with the reduction of R&D and production costs of membrane materials, MBR membrane pools will be applied in more fields to contribute to creating a better ecological environment for mankind.
In summary, MBR membrane tanks play an important role in wastewater treatment. By understanding the role and application prospects of MBR membrane tanks, we can better understand this technology and provide strong support for future wastewater treatment work.
