That soil irrigated land treatment method method is domestic wastewater treatment wastewater treatment method uses the first human, but the application of land treatment system common in urban sewage treatment. For the treatment of domestic wastewater treatment system leachate, the leachate collected, returned to the landfill through sprinklers to make it. Landfill leachate due to increased recycling garbage humidity, thereby increasing the biological activity, accelerate methane production and waste decomposition. Second, because of the evaporation of sprinkler domestic wastewater treatment equipment, so that leachate volume reduction, waste water treatment system is conducive to the operation, and can save energy costs. North of England Seamer Carr landfill leachate recirculation part of domestic wastewater using the processor, COD value 20 months after leachate recirculation zone is reduced more, metal concentrations have decreased substantially, while NH3 -N changes in concentration of Cl- small. Description decreased metal concentration is not only due to the dilution effect caused by the waste may also be caused by inorganic components of its adsorption. Because leachate recirculation has many advantages, so the design of the landfill at the top do not all closed, but should establish regular arrangement of the channel in order to avoid contamination of the surrounding water. Low concentrations of leachate can not be discharged directly, because NH3-N, Cl- concentration is still high, the temperature is low season, less evaporation, biological activity is weak, leachate recirculation effect needs further study. Most of our city as a basic way to landfill waste disposal in the coming period, sanitary landfill disposal will continue to be the basic way of domestic municipal solid waste disposal. Sanitary landfill as the most common method of waste disposal, there are also many pollution problems, especially in the process of a large number of landfill leachate, if not properly handled, water and soil around will cause serious pollution.
