Solid garbage landfill method

Abstract

The invention relates to a solid garbage landfill method. According to the present invention, according to the analysis on the solid garbage landfill treatment pollution influence source from domesticgarbage sorting, selecting or conversion treatment residues, the results show that the pollution release path can be effectively cut off by controlling the contact between the solid garbage and the water during the landfill treatment operation and after the landfill so as to ensure the sanitary landfill. The technical problem to be solved by the present invention is to integrate technical measures, wherein with the technical measures, the garbage cannot contact the environmental water flow during the inert garbage landfill operation and after the landfill. According to the present invention,the solid garbage landfill method with characteristics of reliable environment influence control and saved economic cost is provided, the total cost of the domestic waste diversion and conversion treatment technical system can be easily saved, and the competitiveness and the expandability can be improved, such that the replacement of the traditional mixing landfill treatment with the technical system can be indirectly promoted, and the level of the harmlessness and resource utilization of domestic garbage can be improved.

Description

technical field [0001] The invention relates to a method for landfilling solid waste. Background technique [0002] The mainstream technology for domestic waste landfill disposal is sanitary landfill. The sanitary landfill technology is designed according to the requirements for disposal of mixed domestic waste. Among them, the derivative pollution generated by the degradation of perishable organic matter in domestic waste in the landfill is sanitary landfill. Typical secondary pollutants in landfills: sources of leachate and landfill gas generation. The facilities dedicated to controlling these pollutants in sanitary landfills include: anti-seepage system at the bottom of the landfill, leachate collection and treatment system, landfill gas drainage system, final cover system for water isolation and air closure in the landfill, these facilities The investment accounts for about 40% of the total investment of the landfill, and the operating cost is about 30% of the total cos...

Problems solved by technology

Compared with mixed domestic garbage, the basic characteristics of these garbage (waste) are that they are not biodegradable, and their chemical reactivity is relatively stable, and there is no possibility of producing gas and liquid derivatives due to spontaneous conversion reactions; but Due to the inevitable mutual contamination between components in the process of production, collection and treatment, these garbage may still contain certain pollution components, especially when they are in contact with water, the water in contact with them may become sewage due to the release of pollution. resulting in environmental impact

[0004] Therefore, in terms of controlling the possible pollution impact of these non-biodegradable solid wastes in landfill disposal, the existing sanitary landfill technology is not suitable due to lack of pertinence, and will bring Dealing with resource waste to a certain extent
