Method of producing natural gas by bacterial degradation of domestic waste

Abstract

A method of producing natural gas by bacterial degradation of domestic waste comprises: first, building a natural oil-gas field to treat urban and rural domestic wastes, mainly including a waste mixing tank, a natural oil-gas field, and heavy metal separation tank; second, pouring urban and rural domestic wastes directly into the waste mixing tank that is enclosed, stirring under sealing condition, and pushing the stirred material into the natural oil-gas field; third, in the enclosed natural oil-gas field, allowing specific enzymes, which are in animal viscera and washing fouling fat and blood water from rural slaughterhouses, to be stirred and dispersed to the domestic wastes and to interact with various enzymes, thereby catalyzing the domestic wastes and arriving at high sliming and enhanced free energy reaction; producing natural gas by bacterial degradation; fourth, manufacturing fertilizer with waste residue, to be specific, manufacturing fertilizer directly with the waste residue subjected to heavy metal separation. The method is effective in decreasing contamination of urban and rural domestic wastes, thereby improving the environmental condition and saving land resources;harm can be converted into benefit, and fuel gas can be produced to act as a living fuel, thereby creating economic benefit and social benefit. The method is applicable to all cities and towns.

Description

technical field [0001] The invention relates to the treatment of solid wastes, in particular to the conversion of solid wastes into useful or harmless materials, in particular to the method of converting domestic wastes into natural gas. Background technique [0002] Urban garbage is increasing day by day, while the energy crisis is getting worse day by day. At present, there are many treatment methods for urban domestic waste, such as Chinese Patent No. 98111279X "Garbage Gasification Method for Municipal Waste", No. 200410011274.7 "A Garbage Briquette and Its Production Method", No. 200510004873-0 "A New Type of Harmless Urban Garbage Recycling Device", etc. These methods all have the effect of dealing with garbage to a certain extent and making it resourceful, but these methods have not yet met the requirements of large-scale digestion of municipal solid waste, the effect of improving the environment is not thorough, and some will bring secondary pollution, which consume...

These methods all have the effect of dealing with garbage to a certain extent and making it resourceful, but these methods have not yet met the requirements of large-scale digestion of municipal solid waste, the effect of improving the environment is not thorough, and some will bring secondary pollution, which consumes energy situation and the level of recovery cost, it is still impossible to judge
