Water is the source of life, so the development of water conservancy and the elimination of water hazards are related to human survival and social progress, so sewage treatment is particularly important and critical. Whether it is urban sewage treatment or rural toilets, garbage and sewage treatment, it is a key project for us to restore the environment. In recent years, China has also paid special attention to sewage treatment technology, after all, the application of technology has made sewage treatment targeted.
As a commonly used technology in sewage treatment, MBR membrane element has been focused on, and today the author will take you to understand the four outstanding advantages of MBR membrane technology, which is also the reason for its popularity.
1. As a new and efficient sewage treatment process that combines membrane separation technology with traditional activated sludge method, MBR membrane is a membrane element that is easy to maintain, does not need to backwash during operation, and is easy to disassemble.
2. MBR membrane element has strong anti-fouling ability, which is not easy to form membrane pollution for sewage treatment, and the fouling resistance is better than that of other membrane modules, and can withstand higher sludge concentration.
3. MBR membrane elements ensure that the effluent quality of sewage after treatment meets national standards, can remove colloids, particles and microorganisms in the water body, and completely intercept the activated sludge in the bioreactor.
4. The MBR membrane element replaces the secondary sedimentation tank and the first-class treatment process in the traditional process through the membrane separation device, which can increase the sludge concentration in the bioreactor, thereby improving the overall impact resistance of the system.
On the whole, the treatment effect of MBR membrane element for sewage is far better than that of traditional sedimentation tank, the treated effluent quality is very clear, the suspended solids and turbidity are close to zero, bacteria and viruses are removed, and the effluent quality is better than the domestic miscellaneous water quality standard (CJ25.) issued by the Ministry of Construction1-89), which can be directly used as non-potable municipal miscellaneous water**.
To sum up, these 4 advantages for sewage treatment can be said to be the right medicine, the application of MBR membrane elements solves the problem that the water quality of the traditional sewage treatment process does not meet the discharge requirements, and the treated water source can also be reused for various industrial water under the premise of meeting the sewage treatment.
