Kitchen waste treatment process

Abstract

The invention discloses a kitchen waste treatment process. The treatment process includes the following steps that dewatering is performed, specifically, kitchen wastes can be spread on a material frame, water is collected into oily sewage treatment equipment to be treated, and treated water is discharged to a sewer; and multi-stage sorting of the kitchen wastes is performed, specifically, first-stage hard wastes are sorted manually, recyclable wastes are sorted out to be recycled and treated, hard porcelain and glass in second-stage mixed wastes are sorted out and collected into a special waste can, then the residual mixed kitchen wastes are put in waste treatment equipment to be treated, third-stage soft kitchen wastes are sorted manually, hard glass ceramic wastes are removed, then anaerobic fermentation is performed under a certain condition, and marsh gas and residues are generated.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a kitchen garbage treatment process. Background technique [0002] Kitchen waste is the domestic waste formed by residents in the process of living. It is characterized by rich organic content, large oil content and complex composition. Improper disposal of kitchen waste can easily cause environmental pollution. At the same time, food waste is particularly rich in nutrients and has great recycling value. Therefore, the treatment and comprehensive utilization of food waste has become a research hotspot at home and abroad. At present, the main technologies for food waste treatment include landfill, aerobic composting, direct drying as feed and microbial treatment technology. Landfill technology exists Large area, large amount of leachate, high environmental risk, etc.; aerobic composting treatment technology, but the high oil content and high salt content in kitchen was...

Problems solved by technology

Therefore, the treatment and comprehensive utilization of food waste has become a research hotspot at home and abroad. At present, the main technologies for food waste treatment include landfill, aerobic composting, direct drying as feed and microbial treatment technology. Landfill technology exists Large area, large amount of leachate, high environmental risk, etc.; aerobic composting treatment technology, but the high oil content and high salt content in kitchen waste are not conducive to the growth of microorganisms, and also restrict the high-temperature aerobic composting treatment process Effect

At the same time, the high-temperature aerobic composting treatment technology has a very large area

[0003] However, in the prior art, because the kitchen waste is generally only treated simply, or the treatment process is too complicated, the entire treatment process is very cumbersome, and it is inconvenient to process the kitchen waste.
