Kitchen waste treatment process

Abstract

The invention discloses a kitchen waste treatment process. The kitchen waste treatment process comprises the following steps: 1) draining treatment; (2) sorting treatment; 3) crushing treatment; and 4) breeding hermetia illucens. The method is ingenious and reasonable in design, the kitchen waste is used for feeding the black water gadfly, the kitchen waste is fully consumed and utilized and converted into high-quality and safe insect protein, pollution of the kitchen waste can be solved, high-value black water gadfly biological products can be obtained, pollution is little, follow-up waste water and waste residue treatment is avoided, economic benefits are good, and the method is worthy of popularization and application. And the sorting equipment is adopted in the sorting treatment process, the actual sorting treatment effect is effectively improved, synchronous operation and cyclic conversion of multiple stations are adopted in the sorting equipment, continuous operation of sorting is achieved, and the actual treatment rate and treatment quality are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of kitchen waste treatment, and in particular relates to a kitchen waste treatment process. Background technique [0002] According to the survey, kitchen waste occupies a large proportion of urban domestic waste. The existing kitchen waste treatment technologies mainly include incineration, landfill, aerobic composting and anaerobic fermentation. The incineration method will have the following problems: kitchen waste will produce air pollutants such as dioxins and heavy metals; if it is not treated, it will cause certain harm to the environment; in addition, the moisture content of kitchen waste is relatively high, generally above 80% , more fuel is added during the combustion process. The use of landfill will have the following problems: occupy a lot of land resources, easily generate landfill gas and garbage dust, and if the leachate generated during the landfill process is not properly handled, it will...

AI Technical Summary

Problems solved by technology

The following problems will exist in the incineration method: food waste will produce air pollutants such as dioxins and heavy metals; if it is not treated, it will cause certain harm to the environment; in addition, the water content of food waste is relatively high, generally above 80% , more fuel is added during combustion

The use of landfill will have the following problems: occupying a large amount of land resources, easy to generate landfill gas and garbage dust, and if the leachate generated during the landfill process is not properly disposed of, it will cause secondary pollution of the environment, which will easily lead to problems such as soil pollution and groundwater pollution.

The use of aerobic composting will have the following problems: kitchen waste contains oil, salt, heavy metals and other refractory substances, which cannot be completely oxidized by aerobic microorganisms, and the harmlessness is not complete, which is likely to cause secondary pollution problems

The following problems will exist in the use of anaerobic fermentation: the generated biogas and biogas residue need to be further processed
