Technical principle
MABR water treatment technology is a gas separation membrane technology and biofilm method of water treatment
The technology combines a novel sewage treatment technology, the core part of which consists of hollow
Fibrous membranes and biofilms. The biofilm is attached to the outer surface of the oxygen-permeable hollow fiber membrane.
The air supplies oxygen to the biofilm through the hollow fiber membrane, and the biofilm is fully connected with the sewage
Contact, sewage contained organic matter and ammonia nitrogen by biofilm adsorption and decomposition removed from.
So that the sewage can be purified.
Technical advantages of MABR membrane in river/lake application
The membrane component is directly installed in the river without the construction of the civil pond, in situ purification, ecological safety, a wide range of water quality.
High oxygen utilization rate, oxygen utilization can reach more than 60%, long-term operation, energy saving.
The microorganism comes from the original water body without introducing foreign strains, avoiding ecological security risks, good compatibility, high cost performance
With excellent resistance to hydraulic impact, anti-pollution impact and system self-recovery ability, high compatibility with other technologies, automatic operation, unattended, simple operation management.
Selection principle of treatment Technology for polluted water in river course
Strictly implement relevant national laws, regulations, policies and standards.
Priority should be given to using ecological technology for treatment, combining water pollution treatment with ecological restoration, and establishing corresponding aquatic ecosystem.
The treatment process should have greater flexibility and adjustability in operation to adapt to the change of water quality and quantity.
Protect and use the existing natural terrain, water, vegetation and other landscape conditions, according to local conditions, in situ management, save investment.
It emphasizes the coordination and unity of water body maintenance, river drainage, landscape and other functions, so as not to produce secondary pollution.
Ensure the long-term effectiveness of design features.
