Problems solved by technology

[0006] The problem to be solved by the present invention is that the fermentation time of the existing kitchen waste treatment method is too long, and the fiber products therein cannot be decomposed, and there are many suspended fine residues in the liquid that cannot be effectively separated, which is not convenient for the subsequent treatment of the liquid; at the same time, it can improve The ability to decompose fatty substances and reduce the content of fatty substances in solid waste

Embodiment 1

[0030] The disposal method of kitchen waste includes the disposal method of residue and the disposal method of liquid.

[0031] The kitchen waste is filtered into residues and liquids, the liquids are made into biodiesel, and the residues are made into biofertilizers.

[0032] The treatment method of the residue is as follows: after 100kg of residue is pulverized to 15mm, the pH of the mixture is adjusted to 5.5, then 7kg of bulking agent is added and mixed evenly; the water content of the mixture is measured and adjusted to be 48%; Liquid, multi-bacteria mixed solution is prepared by mixing 3 million cfu / ml white rot bacteria, 3 million cfu / ml lactic acid bacteria, 3 million cfu / ml white rot bacteria, 3 million cfu / ml Aspergillus niger; at a temperature of 40 ° C, ventilation Fermentation was carried out for 42h under the conditions, and the ventilation rate was 4L / min; 1.19kg of potassium dihydrogen phosphate was added and mixed evenly to obtain biological fertilizer.

Embodiment 2

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

[0037] Among them, the bulking agent is prepared by mixing 2.64kg of manure, 0.48kg of sawdust and 4.88kg of sandy soil evenly.

[0038] The liquid treatment method is: pass 100kg of liquid through an ultrasonic pulverizer to pulverize the suspended mat...

Embodiment 3

[0040] The treatment method of the residue is as follows: 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 the water content of the mixture to be 55%; then add 12.5kg of multi-bacteria to mix Liquid, multi-bacteria mixed solution is prepared by mixing 3 million cfu / ml white rot bacteria, 3 million cfu / ml lactic acid bacteria, 3 million cfu / ml white rot bacteria, 3 million cfu / ml Aspergillus niger; at a temperature of 47 ° C, ventilation Fermentation was carried out for 46h under the conditions, and the ventilation rate was 6L / min; 1.88kg of potassium dihydrogen phosphate was added and mixed evenly to obtain biological fertilizer.

[0041] Wherein, the bulking agent is prepared by mixing 3kg of manure, 1.5kg of sawdust and 5.5kg of sand evenly.

[0042]The liquid treatment method is: pass 100kg of liquid through an ultrasonic pulverizer to pulverize the suspended matter in the liquid to...

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 disposal, in particular to a kitchen garbage disposal method. Background technique [0002] Kitchen waste mainly comes from the food waste left by the diet of households, hotels, restaurants, schools and other institutions, enterprises and institutions, and is the waste generated in the process of people's living and consumption; , the output of kitchen waste has increased accordingly; now the world's annual urban domestic waste is about 50 billion tons; the proportion of kitchen waste is 10%-20%; kitchen waste is easy to ferment, deteriorate, and rot, resulting in a large amount of toxins , emits unpleasant odor, and will pollute the land, atmosphere and water body when it accumulates; therefore, the recycling and harmless treatment of kitchen waste is increasingly important. [0003] The existing methods for treating kitchen waste have the following defects: first, the fermentation time needs at ...
