Embodiment Construction

[0020] This embodiment is a preferred implementation mode of the present invention, and other principles and basic structures that are the same or similar to this embodiment are within the protection scope of the present invention.

[0021] Please see attached figure 1 , the present invention is mainly applied to a landfill type garbage dump, which fills the garbage 14 below the horizon 1, and the top of the garbage 14 landfill area is provided with a spray net 6, and the spray net 6 is provided with a spray port for Salt water is sprayed on the garbage 14, and an underground waterproof wall 12 is arranged around the landfill area of ​​the garbage 14. The underground waterproof wall 12 is formed by pouring cement, which can effectively prevent leachate from seeping out and polluting groundwater and reservoirs, etc., and the garbage 14 is filled. The buried area is provided with sinking wells 4, and more than one sinking wells 4 are provided to accommodate seeped landfill leach...

Abstract

The invention discloses a closed-cycle brine spraying system and method for garbage disposal. The system comprises a landfill, a spraying net, an underground waterproof wall, more than one water settling well, a water pump and sewage treatment equipment, wherein the spraying net is arranged above the landfill, the underground waterproof wall is arranged around the landfill and extends downwards to a lithosphere, more than one water settling well is arranged in an area defined by the underground waterproof wall, the water pump pumps leachate in each water settling well into the sewage treatment equipment for treatment, brine is sprayed into the landfill via the spraying net, permeates from the top of garbage to the bottom and enters each water settling well through the lithosphere finally, the mixture of brine and leachate is pumped onto the ground by the water pump and sent into the sewage treatment equipment through a water settling well water outlet pipe, and the leachate is separated out by the sewage treatment equipment.

Description

technical field [0001] The invention discloses a garbage dump treatment structure and method, in particular to a closed-circuit circulation salt water spray system and method for garbage treatment. Background technique [0002] With the continuous development of the economy and the acceleration of the urbanization process, urban waste has become an increasingly serious environmental problem. At present, the main treatment method for urban waste is to set up landfills for landfill treatment. Due to the various components of urban waste, after landfill, it will inevitably produce odor and leachate, which will directly affect the normal life of residents near the landfill, and leachate may pass through rainwater, garbage, etc. The water contained in itself and the groundwater will directly spread the leachate to a distant place, which will endanger the safety of groundwater resources and reservoirs. The treatment of odor and leachate in the existing landfill has become the foc...
