Embodiment 1

[0026] This embodiment takes the treatment of one ton of kitchen waste as an example.

[0027] Step 1. Heat the food waste to float the oil, remove the floating oil, then wash it with water to remove salt and oil, finally filter the food waste, and then crush it through a pulverizer;

[0028] Step 2: Add 300 grams of potassium permanganate to the crushed food waste and stir, then add 400 grams of EM bacteria to obtain a mixed base material, mix the mixed base material evenly with a mixer, and ferment naturally at room temperature for 24 hours at 10°C to obtain fermentation Binder;

[0029] Step 3, laying an earthworm bed of 10 cm with the fermented base material, and cultivating earthworms in the earthworm bed; when the humidity of the earthworm bed is lower than 40%, spray water to replenish water until the humidity of the earthworm bed reaches 60%.

[0030] Step 4. The earthworms are driven out from the earthworm bed by the electric earthworm machine so as to separate the e...

Embodiment 2

[0032] This embodiment takes the treatment of ten tons of kitchen waste as an example.

[0033] Step 1. Heat the food waste to float the oil, remove the floating oil, then wash it with water to remove salt and oil, finally filter the food waste, and then crush it through a pulverizer;

[0034] Step 2: Add 2 kg of potassium permanganate to the crushed food waste and stir, then add 3 kg of EM bacteria to obtain a mixed base material, mix the mixed base material evenly with a mixer, and ferment naturally at room temperature for 24 hours at 30°C to obtain fermentation Binder;

[0035] Step 3: laying an earthworm bed of 5 cm with the fermented base material, and cultivating earthworms in the earthworm bed; when the humidity of the earthworm bed is lower than 40%, water replenishment is carried out by spraying until the humidity of the earthworm bed reaches 60%.

[0036] Step 4: After the earthworms have transformed the fermented base material, separate the earthworms from the verm...

Embodiment 3

[0038] This embodiment takes the treatment of one ton of kitchen waste as an example.

[0039] Step 1. Rinse the food waste with water to remove salt and oil, and finally filter the food waste, and then crush it with a shredder;

[0040] Step 2: Add 400 grams of potassium permanganate to the crushed food waste and stir, then add 600 grams of EM bacteria to obtain a mixed base material, mix the mixed base material evenly with a mixer, and then ferment naturally at room temperature for 24 hours to obtain fermentation Binder;

[0041] Step 3, laying an earthworm bed of 7 cm with the fermented base material, and cultivating earthworms in the earthworm bed; when the humidity of the earthworm bed is lower than 40%, spray water to replenish water until the humidity of the earthworm bed reaches 60%.

[0042] Step 4. The earthworms are driven out from the earthworm bed by the electric earthworm machine so as to separate the earthworms from the earthworm dung, the earthworm dung is use...

Abstract

The invention discloses a method for treating kitchen garbage with earthworms. The method includes the following steps that 1, the kitchen garbage is pretreated, and redundant oil, salt and water areremoved to be smashed; 2, 200 g-400 g of potassium permanganate is added into kitchen garbage per ton, then the mixture is stirred, then 300 g-600 g of EM bacteria are added, a mixed base material isobtained, the mixed base material is evenly mixed to be naturally fermented at the normal temperature, and a fermented base material is obtained; 3, an earthworm bed is laid with the fermented base material, and the earthworms are bred in the earthworm bed; 4, the earthworms and wormcast are separated, the wormcast is used as nutrient soil, and the earthworms are recycled, or serve as animal protein feed. According to the method for treating the kitchen garbage with the earthworms, the kitchen garbage serves as a raw material substance of fermentation, the kitchen garbage is degraded and transformed through microorganisms, the kitchen garbage is made into good feed of the earthworms, and it can be guaranteed that the selected earthworms can survive and are bred in the fermented base material, and the kitchen garbage is fully transformed into animal protein feed and nutrient soil.

Description

technical field [0001] The invention belongs to the technical field of biological treatment of kitchen waste, and in particular relates to a method for treating kitchen waste with earthworms. Background technique [0002] According to statistics, about 30-50% of the food produced in the world every year is wasted. In China, about 60 million tons of food waste is generated throughout the year, which is equivalent to the food for 200 million people for a year. If these food wastes are not treated harmlessly, they will pollute the soil, water sources, and even return to the dining table. At the same time, kitchen waste has high organic content and sufficient nutrients, which implies huge resource utilization value. [0003] Kitchen waste mainly includes catering industry waste, food industry tailings, etc. The channels of its generation are mainly food processing, handling, transportation and other processes, and the sources are mainly concentrated in hotels, food factories,...
