Garbage landfill rapid stabilization system

Abstract

The invention discloses a garbage landfill rapid stabilization system. A leachate horizontal guide and discharge system is arranged at the bottom of a garbage pile, an air exhaust and injection systemand a leachate irrigation and drainage system are inserted into the garbage pile, and the leachate horizontal guide and discharge system and the leachate irrigation and drainage system communicate with a leachate collection well. One end of an air exhaust and injection pipeline in the exhaust and injection system is vertically inserted into the garbage pile, the other end of the air exhaust and injection pipeline is connected with a second control system, and the other end of the second control system is connected with an air injection fan and an air exhaust fan. One end of the leachate irrigation and drainage system is vertically inserted into the garbage pile of a garbage landfill, the other end of the leachate irrigation and drainage system is connected with a third control system, andthe other end of the third control system is connected with a leachate pumping and discharging pump and a leachate lifting pump. By means of the system, sufficient oxygen is provided for garbage landfill, and it is ensured that garbage is subjected to aerobic biochemical degradation. The landfill becomes a composite purification reactor by refilling leachate, nutrient substances in the leachate can be fully circulated in the garbage pile, and the growth metabolic efficiency of microorganisms is effectively improved.

Description

technical field [0001] The invention relates to the technical field of domestic garbage treatment, in particular to a rapid stabilization system for a garbage landfill. Background technique [0002] With the acceleration of urbanization and the improvement of people's living standards in our country, the garbage generated in cities is increasing, which poses a threat to the ecological environment of cities and the health of residents. [0003] At present, a large number of domestic waste landfills have reached the design storage capacity and are facing closure. How to carry out ecological restoration and landscape greening, reduce pollution, realize sustainable use of land resources, and provide urban residents with new and beautiful landscapes and recreational spaces has become an urgent problem to be solved. [0004] Due to the short landfill life of some waste landfills, they are at the peak of gas production, and the waste dumps are in an unstable state. They need to be...

Problems solved by technology

At the same time, the moisture content of the garbage dump has a great influence on the aerobic degradation reaction, which easily leads to incomplete mineralization of the garbage dump and unsatisfactory mineralization effect during the aerobic stabilization process.
