Embodiment 1

[0016] The domestic waste processed in this embodiment is kitchen waste, and the dry powder is diatomaceous earth powder. The food waste disposal method includes the following steps:

[0017] (1) Homogenization: send the garbage to the homogenizer through the feeding port 1 for homogenization treatment to 50 meshes;

[0018] (2) Fermentation: The homogenized food waste is sent to the fermentor 4 through the slurry pump 3 for anaerobic fermentation. The fermentor 4 is equipped with a solar heat conduction tube 5 to heat the fermenter, and ferment at 20°C. Today, the biogas produced during fermentation is sent to the living area for lighting or as a life heat source through the biogas exhaust pipe 6 located on the top of the tank, and the excess biogas is sent to the kiln 15 to be burned into ceramsite with mud balls;

[0019] (3) Mixing into mud ball: the fermented garbage mixture is pumped into the pre-mixing tank 11 through the limited pump 7; the diatomaceous earth powder in the d...

Embodiment 2

[0022] The domestic waste processed in this embodiment is kitchen waste, and the dry powder is lime powder. The food waste disposal method includes the following steps:

[0023] (1) Homogenization: send the garbage to the homogenizer through the feeding port 1 for homogenization treatment to 100 meshes;

[0024] (2) Fermentation: The homogenized food waste is sent to the fermentor 4 through the slurry pump 3 for anaerobic fermentation. The fermentor 4 is equipped with a solar heat conduction tube 5 to heat the fermenter and ferment at 28°C. Today, the biogas produced during fermentation is sent to the living area for lighting or as a life heat source through the biogas exhaust pipe 6 located on the top of the tank, and the excess biogas is sent to the kiln 15 to be burned into ceramsite with mud balls;

[0025] (3) Mixing into mud ball: the fermented garbage mixture is pumped into the pre-mixing tank 11 through the limited pump 7; the diatomaceous earth powder in the dry powder tank...

Embodiment 3

[0028] The domestic waste processed in this embodiment is kitchen waste, and the dry powder is a mixture of limestone powder and diatomaceous earth powder, and the weight ratio of the two is 1:1. The food waste disposal method includes the following steps:

[0029] (1) Homogenization: send the garbage to the homogenizer through the feeding port 1 for homogenization treatment to 200 meshes;

[0030] (2) Fermentation: The homogenized food waste is sent to the fermentor 4 through the slurry pump 3 for anaerobic fermentation. The fermenter 4 is equipped with a solar heat pipe 5 to heat the fermenter and ferment at 35°C 10 Today, the biogas produced during fermentation is sent to the living area for lighting or as a life heat source through the biogas exhaust pipe 6 located on the top of the tank, and the excess biogas is sent to the kiln 15 to be burned into ceramsite with mud balls;

[0031] (3) Mixing into mud ball: the fermented garbage mixture is pumped into the pre-mixing tank 11 t...

Abstract

The invention relates to a method for treating domestic garbage, which sequentially comprises the following steps of: (1) homogenizing, namely homogenizing the domestic garbage by using a homogenizer until the domestic garbage has the particle size of 50 to 200 meshes; (2) fermenting, namely feeding the homogenized garbage into a fermentation tank and performing anaerobic fermentation at the temperature of between 20 and 35 DEG C for 10 to 40 days; (3) mixing to form mud balls, namely premixing the fermented garbage mixed liquid and dry powder in a weight ratio of (8-14):100, and rolling by using a balling disc to form the mud balls with the size of 5 to 12mm; and (4) firing, namely heating the mud balls to the temperature of between 900 and 1,300 DEG C through a kiln, and firing to form ceramsites. Separation is not needed in the method, residual garbage is avoided, restaurant-kitchen garbage, excrement garbage and garbage leachate can be completely comprehensively utilized and innocently treated, and the problem of secondary pollution of the garbage is solved.

Description

Technical field [0001] The invention relates to the field of domestic garbage treatment, in particular to a harmless treatment method for kitchen garbage, fecal garbage and garbage leakage. Background technique [0002] Existing domestic waste treatment methods such as kitchen waste and fecal waste generally use biological composting, dilution, and polymer filtration technologies, which generally have problems such as incomplete treatment, secondary waste and pollution, high investment treatment and operating costs, and low returns. [0003] In order to recycle the domestic garbage in a harmless manner, the Chinese patented method for producing ceramsite using garbage (published on November 19, 2003, publication number CN1456533A), provides a method of processing garbage to turn garbage into ceramics. Granulation method. This method screens out the stale rubbish in the rubbish and dries it to a moisture content of ≤35%, then mixes the dried rubbish with clay and anthracite, and the...
