Description

A harmless treatment device for organic solid waste

Technical field

The invention relates to the technical field of organic solid waste treatment devices, specifically a harmless treatment device for organic solid waste.

Background technique

Organic solid waste mainly includes landscaping waste, municipal sludge, animal inclusions in slaughterhouses, kitchen waste, etc. In order to prevent organic solid waste from causing pollution and harm to the environment and human body, physical, chemical, and Solid waste is treated harmlessly through biological and other methods.

In the process of harmless treatment of organic solid waste, in order to improve the effect of organic solid waste treatment, the existing organic solid waste will be shredded during the treatment process. The shredded organic solid waste will be made into organic fertilizer through biological fermentation to achieve resource recycling. For example, authorized publication number CN112275395B, an organic solid waste treatment device, uses a direct shredding method to process organic waste. Solid waste treatment, however, because some organic solid waste contains moisture inside, during the process of chopping it, the high moisture content will cause the viscosity of the material to increase, making the chopping effect worse. When the shredded organic solid waste is subjected to biological fermentation, it needs to contain appropriate moisture inside to ensure the reproduction and decomposition of microorganisms. It is also necessary to ensure that the moisture in the shredded organic solid waste is appropriate. If the moisture is too high, If there is too much water, it will cause the materials in the compost to decompose too quickly, and if there is too little water, it will cause the materials in the compost to decompose too slowly. Therefore, the direct shredding method will increase the speed of organic solid waste processing. , however, it reduces the quality of organic solid waste treatment. For this reason, we propose a harmless treatment device for organic solid waste.
