Embodiment Construction

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] As shown in the figure, the process steps of the present invention are:

[0022] 1. Dry and wet separation of biological waste

[0023] Residential bio-waste is separated from wet and dry to obtain dry garbage and wet garbage;

[0024] Dry waste is sorted by hand and sent for recycling;

[0025] Wet garbage enters the next step for processing;

[0026] 2. Wet waste treatment

[0027] 1) Crushing, the wet garbage is sent to the pulverizer for pulverization;

[0028] 2) Cooking, the pulverized material is sent to the cooking machine for cooking to achieve the effect of sterilization and oil dissolution;

[0029] 3) Squeeze, steam and cook the processed materials, and send them to the press to be pressed to obtain slag and oily water;

[0030] 4) Oil and water treatment

[0031] A treatment to obtain biogas...

Abstract

The invention discloses a treatment process for biological wastes. The process comprises the following steps of: carrying out dry wet separation of the biological wastes, namely carrying out dry wet separation on household biological wastes to obtain dry wastes and wet wastes; manually sorting the dry wastes, and then sending to recycle; treating the wet wastes, pulverizing, and sending the wet wastes to a pulverizer to pulverize; cooking, namely cooking the pulverized material into a cooking machine so as to achieve the effects of sterilization and fat dissolution; pressing, namely pressing the cooked materials to a presser to obtain residues and oil water; carrying out oil water treatment, namely in an A treatment mode, carrying out anaerobic fermentation on the oil water to obtain methane, and in a B treatment mode, separating oil water by using a separator to obtain oil and water, sending the oil to be used as biological energy sources, such as biodiesel; and carrying out residue treatment, namely adopting the residue as insect feeds, treating the insects obtained by culturing to prepare protein feeds, and utilizing the postbibal feeds of the insects and excrement residues as biofertilizers.

Description

technical field [0001] The invention relates to a treatment method for biological waste, in particular to a treatment process for biological waste. Background technique [0002] Domestic waste in the daily life of residents, its main characteristics are low in protein and fat, mixed with dry and wet. As domestic waste, the treatment process for kitchen waste that the applicant applied for before cannot be applied. Because kitchen waste contains high protein and fat, its treatment method is carried out according to the characteristics of kitchen waste, so it is not suitable for domestic waste treatment. At present, there is no good method for dealing with residents' daily garbage, so as to process and utilize this kind of biological waste, and solve the problems of homology and environmental pollution at the same time. Contents of the invention [0003] The purpose of the invention is to provide a treatment process for biological waste. [0004] What the invention aims t...
