Kitchen refuse disposal system

Abstract

The invention provides a garbage disposal system capable of reducing the load on a public sewage treatment plant by accurately treating water content separated from garbage through a solid-liquid separator. This garbage disposal system 1 comprises a disposer 42 for crushing the garbage, a pump 41 for conveying the crushed garbage with conveying water, the solid-liquid separator 10 for separating the water content from the garbage conveyed by the pump 41, and a garbage treatment unit 46 for treating the solid content separated through the solid-liquid separator 10. The garbage disposal system 1 further comprises a membrane separation activated sludge unit 48 for reducing an organic substance in the water separated from the garbage through the solid-liquid separator 10 and subsequently separating sludge from the water.

Description

technical field [0001] The present invention relates to a kitchen garbage treatment system which pulverizes kitchen garbage discharged from residential quarters such as restaurants, apartments, and commercial and residential buildings, and then transports them with conveying water for treatment. Background technique [0002] In the existing kitchen waste treatment system, the kitchen waste produced in the kitchen of restaurants or apartments, for example, is pulverized by a kitchen waste crusher installed in the kitchen, temporarily stored in a storage tank (container tank), and then transported by water and The pump delivers to the solid-liquid separation device. Then, the kitchen waste transported to the solid-liquid separation device is separated into solid components and water, and the solid components are heat-treated by using a fermentation treatment type kitchen garbage disposer in which aerobic microorganisms are charged, or by putting the solid components into a com...

Problems solved by technology

[0005] However, since the water separated by the solid-liquid separator is conveyed water mixed with kitchen waste and water drained from kitchen waste, it contains a lot of organic matter

Therefore, if the water containing many organic substances (hereinafter referred to as organic waste water) is discharged to the public sewer as it is, the burden on the public sewage treatment facility will be greatly increased, which becomes a problem.

[0006] In addition, the purification tank placed before the organic waste water is discharged to the sewer is composed of a relatively large sedimentation tank, so the system itself is huge, and there is a problem that it is difficult to secure a sufficient installation area.
