Garbage dumping method based on bioreactor principle

Abstract

The invention discloses a garbage dumping method based on a bioreactor principle, comprising the following steps of: dumping garbage, recharging percolate (concentrate), carrying out micro-biological degradation to generate dumping gas, and collecting and processing the percolate, wherein after the step of dumping garbage begins, the dumped garbage is recharged by the percolate (concentrate) generated after the filtered percolate is collected and processed in the dumped garbage; in the micro-biological degradation process, the dumping gas is generated; and the generated percolate which reaches the standard is externally discharged. The garbage dumping method disclosed by the invention has the advantages of stronger biodegradation function, high garbage biodegradation speed, short stabilization time, high dumping gas yield, complete collection of the dumping gas, no need of a percolate treatment facility and saved cost.

Description

technical field [0001] The invention relates to the technical field of urban garbage treatment, in particular to a garbage landfill method based on the principle of a bioreactor. Background technique [0002] With the development of our country's social economy and the improvement of people's living standards, the requirements for the urban environment are getting higher and higher, and it is necessary to seek new waste disposal technologies. Landfill technology is currently the main garbage disposal method at home and abroad. In my country, landfill treatment accounts for about 70% of the total garbage treatment volume, and my country's national conditions and the characteristics of urban domestic garbage (high content of kitchen waste, high moisture content , low calorific value and complex garbage composition) also determines that for a long period of time in the future, landfill treatment technology will still be the main treatment method for urban domestic waste in my co...

Landfill technology is currently the main garbage disposal method at home and abroad. In my country, landfill treatment accounts for about 70% of the total garbage disposal volume, and the national conditions of our country and the characteristics of urban domestic garbage (high content of kitchen waste, high moisture content , low calorific value and complex garbage composition) also determines that for a long period of time in the future, landfill treatment technology will still be the main treatment method for urban domestic waste in my country, but the current traditional landfill treatment technology only treats landfill As a system that passively accepts garbage, the biodegradation of garbage is a natural degradation process without any control. Due to the structural design problems of traditional domestic garbage landfills - the "dry grave" of garbage is buried, and the humidity of buried garbage is low. Unable to provide a suitable condition for the growth of microorganisms, the biodegradation of waste is thus limited, and the natural degradation rate of landfill waste is very slow, even after a long period of time (30 to 50 years) after the closure Carry out maintenance and management, such as treating leachate, guiding and burning landfill gas, etc.
