Method and special device for organic waste natural degradation

Abstract

The invention provides a method and a special device for organic waste natural degradation. The device comprises a smashing device, sawdust storage device, at least one early-period degradation groove device, at least one later-period ripening groove device and a control system. The device is adopted in the method, the smashing device smashes sawdust and organic waste, then the early-period degradation groove device is utilized to degrade the sawdust and the organic waste in the early period, and the later-period ripening groove device is utilized to degrade the sawdust and the organic waste in the later period. The method and the special device for the organic waste natural degradation adopt the natural temperature rising principle, cultures do not need to be added, a large number of microorganisms carried by the organic waste self are fully utilized, the device creates a good environment for the microorganisms, the microorganisms are stimulated to propagate in quantity and power consumption is reduced to the maximum limit.

Description

technical field [0001] The invention relates to the technical field of organic waste treatment, in particular to a method and special equipment for natural degradation of organic waste such as kitchen waste and kitchen waste. Background technique [0002] At present, the most widely used in-situ treatment equipment on the market is the electric heating degradation equipment, and its technical defects are as follows: [0003] 1. Small volume: The electric heating equipment adopts the concept of "one in and one out", and the volume of its degradation tank can only accommodate the organic waste put in for 1-2 days. That is to say, after a certain amount of organic waste is put in, it must be taken out after a maximum of 48 hours. Frequent discharge will waste a lot of manpower. [0004] 2. High energy consumption: Due to the small volume, the amount of organic waste must be reduced quickly, and because the water content in organic waste is as high as 80%, "drying" is the faste...

AI Technical Summary

Problems solved by technology

That is to say, after putting in a certain amount of organic waste, it must be taken out after a maximum of 48 hours. Frequent discharge will waste a lot of manpower

[0004] 2. High energy consumption: Due to the small volume, the amount of organic waste put in must be reduced quickly, and because the water content in organic waste is as high as 80%, "drying" is the fastest way to reduce it

The cost of bacteria is quite expensive, and the amount added must be very accurate - too little, the degradation efficiency is low; too much, the cost will increase

[0006] 4. Low degradation efficiency: Due to mechanical structure problems, the material must be discharged once within 48 hours, which means that the maximum residence time of organic waste in the equipment is only 48 hours, and microorganisms cannot decompose organic waste in such a short period of time. The waste is completely degraded, so that what is taken out of the equipment is not organic fertilizer at all, but only degraded semi-finished products. If it is piled up in the open air, it will still stink and breed mosquitoes, causing secondary pollution to the environment

[0007] 5. Low adaptability: Since the electric heating equipment only includes a degradation tank and a control system, hard organic waste such as bones cannot be directly put into the equipment, and must be crushed in advance

However, the crushing equipment needs to be purchased separately by the user, which virtually increases the operating cost of the user, and hard organic waste such as bones must be manually transferred to the degradation equipment after crushing (the grinding equipment is independent of the degradation equipment)
