LM high-efficiency infiltration submerged flow artificial wetland system uses the innovative double-tube infiltration water distribution technology independently developed by our company, which systematically solves the technical problems of short flow, runoff, blockage, low sewage treatment efficiency and poor effect in ordinary surface flow artificial ecological wetland systems when treating sewage. It can improve the sewage treatment efficiency of ordinary surface flow artificial wetland technology by 30% to 50%. It allows sewage to be evenly infiltrated into the wetland system composed of composite fillers and plants without energy consumption, effectively removes pollutants in sewage through the formed biological system, and enables the system to deeply remove phosphorus and nitrogen, and treat sewage stably and efficiently for a long time.

Technical advantages:

1. The system relies on ecological energy such as solar energy, bioenergy, gravity energy, etc. It is simple and reliable to operate, requires little maintenance, does not require special personnel to manage, has no secondary pollution, and has almost zero operating costs;

2. The innovative technology of efficient immersion water distribution can effectively prevent short-flow and runoff of sewage in the system;

3. This innovative technology can backwash the system regularly, which can effectively prevent the system from being blocked;

4. Low investment, no need for long-distance, large-scale supporting pipe network construction, the total investment is only 1/4-1/2 of the scale of traditional centralized sewage treatment;

5. The effluent quality is good. Different system designs can be carried out according to the inlet water quality and effluent water quality requirements. The highest effluent water quality can reach the fourth category standard of the "Surface Water Environmental Quality Standard" (GB3838-2002), or the first level standard of the "Pollutant Discharge Standard for Urban Sewage Treatment Plants" (GB18918-2002);

6. The system operates stably, has strong impact resistance, and is not affected by rainy seasons or floods;

7. Rapidly improve the quality of urban and rural systems, increase green space, and improve and beautify the ecological environment.

Application areas:

1. Domestic sewage treatment in small and medium-sized towns and villages;

2. Ecological management of stinky rivers;

3. Ecological restoration of lakes, inland rivers, reservoirs and other water bodies;

4. Recycled water treatment;

5. Maintain landscape water quality;

6. Livestock and poultry wastewater treatment.
