Water, as a resource for people to survive and develop, is the source of life. However, with the development of modern society, a large amount of water resources have been polluted, and the fresh water resources available to people are decreasing little by little. Sewage treatment is also a big problem. Rivers are encroached by sewage, seriously affecting people’s lives. Therefore, sewage treatment has always been an issue that people attach great importance to.
MBR is a new sewage treatment technology developed in recent years by combining traditional sewage biological treatment technology with high-quality membrane separation technology. technology. The application of polytetrafluoroethylene MBR flat membrane in sewage treatment has the following characteristics.
It can perform solid-liquid separation very well. Its separation effect is better than that of traditional sedimentation tanks, and it occupies less space. The water quality obtained through the membrane separation device is very good. . Can be reused directly. The bioreactor can maintain a high concentration of bioreactors. The membrane separation device can prevent high molecular weight organic matter and suspended solids from flowing out of the system and keep the microorganisms participating in the reaction within the bioreactor. This is especially beneficial for microorganisms with a long interception generation time. The membrane can retain many macromolecules that are difficult to degrade with a slow decomposition rate, and improves their degradation efficiency by extending their residence time; the remaining sludge output is small and the sludge treatment cost is low. Easy to realize automation and convenient operation and management.
The currently independently developed polytetrafluoroethylene MBR flat membrane is the core material of the MBR process. The filtration precision is adjustable and is excellent. Different bubble point pressures meet different filtration precisions, uniform membrane pore size distribution, pore-making capacity of 0.1-1μm, wide chemical applicability, biological reliability and pyrogen control. PTFE MBR flat membrane has two categories: hydrophilic and hydrophobic. When used for gas filtration, it can intercept all small bacteria and particles above 0.02μm.
