Household kitchen waste fertilizer treatment device and treatment method thereof

Abstract

The invention discloses a household kitchen waste fertilizer treatment device and a treatment method thereof. The treatment device comprises a vertical tank, wherein a guide plate is arranged inside the tank; the guide plate is perpendicular to a central position of the tank; the inner cavity of the tank is partitioned into two reaction chambers by the guide plate; the upper sides of the two reaction chambers are communicated by virtue of the inner cavity on the top of the tank, and the lower sides of the two reaction chambers are communicated by virtue of an inner cavity at the bottom of thetank; a feed pipe is arranged on the upper part of one side of the tank; a feed bin is connected outside the feed pipe; a crushing propeller is arranged in the feed bin; a discharge pipe is arranged on the other side of the tank; a bottom mud pipe is arranged at the bottom of the tank; an exhaust pipe is arranged on the top of the tank; a pressure release valve is arranged on the exhaust pipe. Thehousehold kitchen waste fertilizer treatment device has functions of crushing, biological treatment and organic fertilizer production and is environmental-friendly, sanitary and simple in operation,organic fertilizers can be produced when household kitchen wastes are treated, requirements of home growing plants or residential greening plants on the fertilizer are met, and development of modern city agriculture can be promoted.

Description

technical field [0001] The invention belongs to the field of solid waste treatment, and in particular relates to a household kitchen waste fertilizer processor and a treatment method thereof. Background technique [0002] Existing domestic garbage disposer mainly contains two types of mechanical grinding type and biochemical treatment type abroad. The grinding type is a kind of garbage disposal equipment that uses crushing as the main treatment method. It is installed under the kitchen sink and connected to the drain pipe. It uses centrifugal force to crush the food waste in the crushing chamber and discharge it into the sewer. The biochemical treatment type is more environmentally friendly. The current foreign practice is to crush the garbage and flow it into a sewage treatment tank built by the government. After fermentation, it will be turned into biogas to provide energy for resource recycling. At present, the most common household garbage disposer in China is the abras...

AI Technical Summary

Problems solved by technology

[0004] However, the main problems in the existing above-mentioned technologies are: the existing household garbage disposer crushes the food waste and discharges it into the sewer, which may cause pipeline blockage; the garbage left in the processor rots and produces stench and breeds bacteria; Sewage treatment plants cause difficulties in treatment; due to the dispersion of kitchen waste, it is difficult to realize on-site mechanized rapid extrusion of solid-liquid and oil-water separation, etc.
