Embodiment 1

[0026] Step 1: Put 100 kg of recycled food waste into the screw press solid-liquid separation device to separate the solid material and liquid oil and water in the food waste;

[0027] Step 2: putting 30 kg of the separated solid material into a microwave drying device for sterilization and drying;

[0028] Step 3: Sorting the sterilized and dried solid materials, and sorting out the non-organic debris;

[0029] Step 4: Crushing and packaging the sorted solid materials.

[0030] Step 5: Add 1.5 kg of coal-water slurry composite additive and 5 kg of lime fine powder desulfurizer to the separated 70 kg of liquid material for emulsification.

[0031] Step 6: Add 120 kg of coal powder that has reached the required fineness into a high-shear emulsifier to make oil-water coal slurry. The prepared coal-oil-water slurry utilizes 61% by weight of raw coal, 35.6% by weight of liquid material, 0.8% by weight of composite additive for coal-water slurry, and 2.5% by weight of lime fine p...

[0034] Step 1: Put 100 kg of recycled food waste into the screw press solid-liquid separation device to separate the solid material and liquid oil and water in the food waste;

[0035] Step 2: put 32 kg of the separated solid material into a microwave drying device to sterilize and dry;

[0036] Step 3: Sorting the sterilized and dried solid materials, and sorting out the non-organic debris;

[0037] Step 4: Crushing and packaging the sorted solid materials.

[0038] Step 5: Add 1.8 kg of coal-water slurry composite additive and 3 kg of lime fine powder desulfurizer to the separated 68 kg of liquid material for emulsification.

[0039] Step 6: Add 110 kg of coal powder that has reached the required fineness into a high-shear emulsifier to make oil-water coal slurry. The prepared coal-oil-water slurry utilizes 60.2% by weight of raw coal, 37.2% by weight of liquid material, 0.98% by weight of composite additive for coal-water slurry, and 1.6% by weight of lime fine powder des...

Abstract

The present invention relates to the technical field of treating garbage, and particularly relates to a method for resource utilization of food waste and slaughter-house garbage. The method comprises the following steps: separating garbage resources into solid state materials and liquid state materials by a solid-liquid separator; sterilizing and drying the separated solid state materials and sorting the non-organic material for crushing and packaging; sterilizing the separated liquid state materials with high temperature and adding a quantitative coal water slurry composite additive and an alkalescent desulfurizer for emulsifying; grinding coal into powders through a milling apparatus; mixing the emulsified mixed liquor in a step 6 and a powdery coal in a step 7 and then placing into a pulping apparatus for preparing oil coal water mixture. The food waste and slaughter-house garbage can be thoroughly treated according to the invention, the method is capable of treating solid garbage as well as treating oil and water in liquid state without generating secondary pollutant; the invention has the advantages of low treatment cost, good utilization efficiency, low investment, easy implementation and good process effect.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, and in particular relates to a resource utilization method for catering and slaughtering garbage. Background technique [0002] Catering waste refers to organic matter such as leftovers, leftovers, vegetable leaves, and fruit peels that are easily decomposed by microorganisms. It is mainly composed of starch, dietary fiber, animal fat, etc., and is mainly produced through food processing, treatment, and transportation. It is the main component of the organic phase in municipal solid waste, with high water content, high oil and salt content, perishable, fermented, Smelly and other characteristics. Slaughter waste is animal offal, fur, dregs, blood and sewage discarded in slaughterhouses. At present, the management of catering and slaughtering waste in most cities in China is disorderly and arbitrary, and catering waste has become the main source of pollution for garbage collection, tra...
