Abstract

New method and application of innocent energylization treatment for urban house garbage. Separate the house garbage, break up; add lime, binding agent and burning-rate accelerator, finally, form, solidify and dry; the product can be used to low-calorie fuels for cement manufacture. This invention needs low cost, simple to operate and provides new resource and application for building material.

Description

Technical field: [0001] The invention relates to the development and application of an environmental protection technology, in particular to a new technology and new application of harmless and energy-based treatment of urban domestic garbage. Background technique: [0002] The amount of urban domestic waste in my country is increasing at an average annual rate of 9%, and the average annual growth rate of some urban domestic waste is 15-20%. The per capita daily domestic waste is 1.16kg. The amount of domestic waste piled up around the city has reached more than 6 billion tons over the years, occupying at least 500 million square meters of ground. Now, the newly increased urban domestic waste in the country is placed in simple landfills or open-air piles in the suburbs of cities and along rivers. More than 80 million tons. [0003] The direct stacking and simple burial of domestic waste release a large amount of harmful gases into the atmosphere, which contain carcinogenic ...
