With the expansion, improvement and development of membrane industry market, the material and cost of membrane products will change greatly. Therefore, the development prospect of membrane technology in the treatment of landfill leachate is great.
Compared with biological treatment and physicochemical treatment, MBR technology has better treatment efficiency. In the treatment process of landfill leachate, MBR membrane does not change phase and energy consumption is low;
The service life of the membrane is long, the fouling of the membrane group is less, and the pollution is reduced;
The system has strong expansibility, and primary, secondary or high-pressure membrane groups can be added as required.
The separation device of membrane separation method is simple, easy to operate and control, convenient for maintenance and management, high separation efficiency, high reliability, small floor area, and can start and stop work frequently, which is very flexible;
The carbon dioxide produced by waste degradation is dissolved in the landfill leachate, making it slightly acidic. This acidic environment intensifies the dissolution of water-insoluble carbonates, metals and their metal oxides in the landfill. Therefore, the leachate contains a variety of metal ions with high concentrations.
