Resource-reutilizing circulating process of biological garbage

Abstract

The invention relates to a biological waste resource-treating cycle technique, which is characterized in that: it comprises source classifying, breaking, preparing porous biological waste brick, constant high temperature anaerobic fermentation, collecting methane and generating electricity, treating smoke, cleaning organic humus, sterilizing and drying. Said invention dewaters the biological waste to prepare porous biological waste brick to be fed into cycle high temperature anaerobic reactor; and use solar energy and the methane generated by biological waste to supply needed heat energy and electricity. The invention can transform the biological waste into methane and non-pollution humus, to significantly reduce filter liquid and the toxic component of filter solution to realize internal energy supply and transform the one-time waste embedding factory into cycled high-temperature anaerobic reactor, to save land consumption.

Description

Technical field: [0001] The invention relates to a domestic waste treatment process, in particular to a biomass waste recycling process for the biomass waste obtained through source classification of the domestic waste. Background technique: [0002] With the enrichment and diversification of social consumer products and the acceleration of urbanization, the disposal of municipal solid waste has always been one of the most concerned problems of the government. Under the guidance of the national policy of developing circular economy, recycling of domestic waste is the only and necessary economic path for waste disposal. [0003] At present, there are a number of patented technologies related to domestic waste treatment technology that have been authorized in my country, such as "a small town's domestic waste treatment process", "urban domestic waste treatment process", "urban domestic waste treatment process and equipment", etc. But they all involve the treatment of mixed mun...

Problems solved by technology

[0003] At present, there are a number of patented technologies related to domestic waste treatment technology that have been authorized in my country, such as "a small town's domestic waste treatment process", "urban domestic waste treatment process", "urban domestic waste treatment process and equipment", etc. But they all involve the treatment of mixed municipal solid waste. In practice, either because of incomplete mechanical sorting and high operating costs, or because of the limitation of processing capacity, they cannot replace the most conventional two kinds of solid waste treatment. Process: landfill and waste-to-energy

[0004] Landfill: The biggest advantage is low construction cost and easy operation; the disadvantage is that it occupies a large amount of land. At the same time, with the requirement of harmless treatment of mixed leachate, a large amount of operating costs are increased, and expensive land costs due to scarce urban land resources , especially the linear use pattern from landfill to scrap in traditional landfills, not only makes a lot of scarce urban land resources be abandoned, or can only be improved into green land, but also makes it impossible to realize a large amount of biogas resources due to the
