Kitchen waste comprehensive treatment system and method

Abstract

The invention relates to environment-friendly equipment and a using method thereof, in particular to a kitchen waste comprehensive treatment system and method. According to the method, a kitchen waste collecting vehicle conveys collected kitchen waste into a feeding bin to be stored and then lifts the kitchen waste to a sorting platform through a spiral conveyor, plastic, metal, glass, porcelain bowls and other residues difficult to biodegrade are manually sorted out, the residues difficult to biodegrade are classified and recycled, the spiral conveyor and the sorting platform are of stainless steel structures, the sorted kitchen waste is soft organic waste easy to crush, and the kitchen waste enters a crushing and squeezing machine to be crushed and dehydrated; and organic residues generated by crushing and squeezing can be used for breeding insects, the insects can be used for producing feed and turning waste into wealth, kitchen wastewater is heated to realize oil-water layering and then is subjected to three-phase separation to realize oil-water residue separation, generated grease can be recycled for preparing biodiesel, after being treated, the wastewater can be used as an external supply carbon source of household garbage leachate for biological denitrification, and sludge is returned to the front end of crushing and squeezing for treatment.

Description

technical field [0001] The present invention relates to an environmental protection equipment and a method of using the same, specifically a comprehensive treatment system and method for kitchen waste. Background technique [0002] The classification and separate treatment of food waste is conducive to the creation of a conservation-oriented and environmentally friendly society. Currently, the country is vigorously promoting the classification and separate treatment of food waste. Food waste has the characteristics of perishability, high organic matter content, high grease, high salt content, and strong odor. Currently, food waste is mainly sent to domestic waste landfills for landfill treatment. Because food waste is perishable, High mobility and the production of odorous gases will inevitably increase the burden on landfills and pose major safety hazards to landfill operations. At the same time, they produce odorous gases that pollute the surrounding atmospheric environmen...

Problems solved by technology

Food waste has the characteristics of perishability, high organic content, high fat, high salt content, and heavy odor. Currently, food waste is mainly sent to domestic waste landfills for landfill treatment. The high fluidity and the generation of foul-smelling gas will inevitably increase the burden on the landfill site and pose a major safety hazard to the landfill operation. At the same time, the foul-smelling gas will pollute the surrounding air environment and endanger the physical and mental health of the surrounding people.
