Stale refuse disposal technique is similar to household refuse disposal. After disposal of stale refuse from landfill, the company utilizes Soil Vapor Extraction (SVE) technology to remove Volatile Organic Compounds (VOCs) and methane in soil. This technique injects air into polluted areas by inject wells and utilizes vacuum pump to produce negative pressure. When the air flows through polluted areas, the air desorbs and brings VOCs from soil back to the ground by extracting wells. Extracting air goes through purification disposal by active carbon adsorption or biological treatment and then the air can be discharged or injected into the underground for reuse. SVE has advantages of low cost, strong maneuverability, adopting standard equipment, broad scope of organics disposal, no destruction of soil structure and no secondary pollution. Removal rate of petroleum hydrocarbons pollutants in benzene series and other light components reaches 90%.
The company utilizes Multi-layer Enhance Groundwater Remediation Technology to remediate underground water in landfill. This technology is a new underground water remediation technique made up of pumping water system, distribution system, remediation system, recirculation system and monitor system.
