Embodiment 1

[0030] The treatment methods of kitchen waste include residue treatment methods and liquid treatment methods.

[0031] The kitchen waste is filtered into residue and liquid, the liquid is made into biodiesel, and the residue is made into biofertilizer.

[0032] The treatment method of the residue is: after crushing 100kg of residue to 15mm, adjust the pH of the mixture to 5.5, then add 7kg of bulking agent and mix evenly; measure and adjust so that the water content of the mixture is 48%; then add 9.73kg of multi-bacteria mixture Liquid, the multi-bacteria mixture is prepared by mixing 3 million cfu / ml Geotrichum candidum, 3 million cfu / ml lactic acid bacteria, 3 million cfu / ml white rot fungus, and 3 million cfu / ml Aspergillus niger; at a temperature of 40°C, ventilation Under the conditions of fermentation for 42 hours, the ventilation rate is 4L / min; 1.19kg of potassium dihydrogen phosphate is added and mixed evenly to obtain a biological fertilizer.

[0033] Among them, t...

Embodiment 2

[0036] The treatment method of the residue is: after crushing 100kg of residue to 20mm, adjust the pH of the mixture to 5.6, then add 8kg of bulking agent and mix evenly; measure and adjust to make the water content of the mixture 50%; then add 11.05kg of multi-bacteria mixture Liquid, multi-bacteria mixture is prepared by mixing 3 million cfu / ml Geotrichum candidum, 3 million cfu / ml lactic acid bacteria, 3 million cfu / ml white rot fungus, and 3 million cfu / ml Aspergillus niger; at a temperature of 45°C, ventilation Under the conditions of fermentation for 44 hours, the ventilation rate is 5L / min; 1.46kg of potassium dihydrogen phosphate is added and mixed evenly to obtain a biological fertilizer.

[0037] Among them, the loosening agent is prepared by mixing 2.64kg of excrement, 0.48kg of sawdust, and 4.88kg of sand and soil evenly.

[0038] The liquid treatment method is: pass 100kg of liquid through an ultrasonic pulverizer to crush the suspended matter in the liquid to 20u...

Embodiment 3

[0040] The treatment method of the residue is: after crushing 100kg of residue to 20mm, adjust the pH of the mixture to 6, then add 10kg of bulking agent and mix evenly; measure and adjust to make the water content of the mixture 55%; then add 12.5kg of multi-bacteria mixture Liquid, the multi-bacteria mixture is prepared by mixing 3 million cfu / ml Geotrichum candidum, 3 million cfu / ml lactic acid bacteria, 3 million cfu / ml white rot fungus, and 3 million cfu / ml Aspergillus niger; at a temperature of 47°C, ventilation Under the conditions of fermentation for 46 hours, the ventilation rate is 6L / min; 1.88kg of potassium dihydrogen phosphate is added and mixed evenly to obtain a biological fertilizer.

[0041] Among them, the loosening agent is prepared by mixing 3kg of manure, 1.5kg of sawdust, and 5.5kg of sand and soil evenly.

[0042]The liquid treatment method is: pass 100kg of liquid through an ultrasonic pulverizer to crush the suspended matter in the liquid to 30um; then...

Abstract

The invention discloses a kitchen waste treatment method. The problems that an existing kitchen waste treatment method is excessively long in fermentation time and fiber cannot be decomposed are mainly solved. The kitchen waste treatment method comprises the following steps that kitchen waste is filtered into residues and a filtrate, the filtrate is manufactured into biodiesel, and the residues are reserved for use; the residues are smashed to the specification being 30 mm or less, the pH is adjusted to be 5.5-6.5, and then 7-15% of a bulking agent is added for uniform mixing so that the water content can reach 48-62%; then, the mixture and a multi-bacterium mixed solution are mixed uniformly on the basis that the weight ratio is 88:8-12; the multi-bacterium mixed solution comprises down mold, lactic acid bacteria, white rot fungi and aspergillus niger; the soluble salt containing N, P and K is added as needed. According to the kitchen waste treatment method, the purposes of shortening the fermentation time and decomposing fiber in the residues are achieved, and the high practical value and the popularization value are achieved.

Description

technical field [0001] The invention relates to the field of kitchen garbage treatment, in particular to a kitchen garbage treatment method. Background technique [0002] Kitchen waste mainly comes from the food waste left by government agencies, enterprises and institutions such as families, hotels, restaurants, schools, etc., and is waste generated in the process of people's life and consumption; , the output of kitchen waste increases accordingly; now the world produces about 50 billion tons of municipal solid waste every year; the proportion of kitchen waste is 10%-20%; kitchen waste is easy to ferment, deteriorate and rot, and produces a lot of toxins , emits an unpleasant smell, and will pollute the land, air, and water when accumulated; therefore, the recycling and harmless treatment of kitchen waste is becoming increasingly important. [0003] The deficiencies in the existing methods for dealing with kitchen waste include: first, the fermentation time needs at least...
