Garbage disposal way generally can be divided into several approaches such as sanitary landfill, incineration and compost.
Landfill is the yard in sanitary landfill method of garbage, waste sanitary landfill is widely used because of low cost, good hygiene level.
Landfill landfill generally adopts stratified soil way to deal with rubbish, accumulating a
Layer of garbage after covering a layer of loess, this is easy to reduce garbage pollution.
Landfill sites including site selection, design and construction, the construction of landfill waste late entry conditions, running, sealing field, maintenance and management and pollution control and monitoring program.
Biological method is one of the most commonly used in leachate treatment method, due to its relatively low operation cost, high treatment efficiency, won't cause secondary pollution such as chemical sludge, which are widely used in the world. Rubbish infiltration processing plant species specific technology form traditional activated sludge process, stabilization pond, biological rotating disc, fixed anaerobic membrane bioreactor, etc.
With the land law to deal with the main form of leachate is plant and soil leachate injection processing system.
In trials of leachate injection production in the UK found that the leachate recharge not only because of the role of evaporation can reduce leachate quantity, but also can greatly reduce the content of organic matter in leachate.
Soil plant processing system (S - P) not only use of physicochemical and biochemical functions of soil or Chen garbage, and use of plant roots on the microorganisms reinforcement and phytoremediation technology. Established in Sweden in 1985-1986 large-scale field S - P system experiment, the system occupies a total area of 22 hectares of landfill site in 4 ha, including 1.2 hectares planted willow, another 2.8 hectares planted all kinds of herbs. Test on the edge of the area for landfill 3 slope, planted 30000 willow tree. In the first three years, testing into the test area of leachate totaling 3290 mm, measured the average annual evaporation is 340 mm, for the precipitation of %, and regions before the test the average annual evaporation is 140 mm, 19% of annual precipitation, evaporation capacity increased two to three times. The system not only have the function of reduction, can reduce the concentration of leachate, such as the concentration of nitrogen average fell 60%, tendency for L fell from 6.93 to 2.96 tendency for L, to be sure with the development of the willow tree growth and root, it may further improve treatment effect.
