Description

Small-size portable landfill leachate processing apparatus

Technical Field

The utility model belongs to the technical field of garbage treatment, and particularly relates to a small-sized movable garbage leachate treatment device.

Background

The landfill leachate is high-concentration organic wastewater derived from water contained in the garbage, rain and snow water entering a garbage pile and other water. The kitchen waste in domestic garbage has the content of kitchen waste components as high as about 60 percent and the moisture content as high as more than 50 percent, and is quite different from the garbage which is mainly made of paper and plastics and has low moisture content in developed countries, and the treatment of percolate is an important step for garbage treatment.

If the landfill leachate is directly discharged into the environment without being treated, serious environmental pollution can be caused. For the purpose of protecting the environment, it is essential to treat the leachate. However, most of the existing landfill leachate treatment systems are large purification systems at the bottom of a landfill site, and leachate in the garbage needs to be collected and treated again. The landfill height of domestic garbage landfill sites in China is mostly more than 40 meters. Along with the increase of the landfill height, the stack body is continuously compacted, the porosity is reduced, and meanwhile, the garbage is gradually degraded to cause the stack body to be settled. According to research, the permeability coefficient of the landfill body decreases along with the increase of the landfill depth, and can reach 10-6 cm/s at the lowest, and is similar to a water-impermeable layer. And the blockage of the percolate guide and discharge system is the result of the comprehensive physical, biological and chemical effects in the landfill, because domestic garbage components in China are complex, the content of suspended particles in the percolate is high, when the percolate carrying high suspended particles flows through the guide and discharge layer, the suspended particles are intercepted and deposited, the porosity of the guide and discharge layer is reduced, and physical blockage is formed. Especially, when the non-woven fabric protective layer is laid on the upper part of the guide and discharge layer, suspended particles are efficiently intercepted, pores of the non-woven fabric structure are rapidly blocked, deposition occurs on the pores, and a water-impermeable layer can be formed within several months. In addition, uneven settlement of the landfill body can cause strong deformation and distortion of the percolate drainage pipe, and further reduce drainage guide efficiency.

It is therefore necessary to treat landfill leachate in advance of the time it enters the landfill.
