Landfill leachate is a kind of high-concentration organic wastewater with quite complex composition. It has high BOD5 and COD concentrations, high metal content, large changes in water quality and water content, high ammonia nitrogen content, and improper proportion of microbial nutrients. If left unchecked, the surrounding farmland and water system will be seriously polluted, especially the groundwater or surrounding environment will be polluted, and the consequences will be more serious. For the purpose of protecting the environment, it is particularly necessary to treat the leachate.

     The advanced and mature technology "two-stage DTRO process" for landfill leachate treatment equipment is flexible and simple, easy to operate, and quick to debug. It can meet the requirements of high standard effluent discharge. The treatment of landfill leachate was quite effective at that time!

     1. Small footprint and simple process.

     2. Mature technology, stable and reliable, high processing efficiency, stable effluent water quality; strong shock load resistance, compact structure, small size; no need for sludge backflow, no blockage, maintenance and management.

     3. Advanced technology and high degree of automation: The system adopts automatic control to facilitate daily operation management and maintenance. At the same time, it considers manual operation functions to facilitate maintenance.

     4. Engineering measures with a certain impact load resistance during the process (the quality and quantity of waste liquid should be fully considered with time and seasonal changes).

     5. The operating cost is economical and reasonable, which is conducive to energy saving and consumption reduction, lowering operating costs, and easy to maintain and manage;

     6. Sewage treatment technology requires flexible operation, and has a good impact load capacity for changes in water quality and volume to ensure that the quality of the effluent water meets the treatment requirements.

     7. The imported MBR membrane has high membrane flux, strong anti-fouling, no backwashing is required, the treated water is extremely clear, and the amount of remaining sludge is small, which reduces the system operating cost.

     8. Adopting advanced RO reverse osmosis membrane, low osmotic pressure and reliable system, which greatly increase the concentration of concentrated body
