Nowadays, in the face of the increasing trend of organic waste such as kitchen waste, food kitchen, fruits and vegetables, garbage treatment equipment has already started to operate in major government departments. In the future, it may become a daily garbage treatment equipment. However, in the process of using waste treatment equipment, aerobic composting is an important process to transform organics into nutrients needed by biology. Aerobic composting is a process in which aerobic microorganisms degrade and transform organics in livestock manure waste into stable humus under aerobic conditions. Do you know what the aerobic composting process of waste treatment equipment is like? The following waste treatment equipment manufacturer - Jiangsu Light Stone Technology will introduce to you:

The process of aerobic composting of waste treatment equipment is as follows:

1. Pretreatment

Pretreatment is also known as pretreatment, which mainly includes pretreatment processes such as sorting, sorting, crushing, screening and mixing. This process is mainly used to remove non composting materials such as large blocks, stones and metals, so as to facilitate the garbage treatment equipment to enter the next step of treatment.

2. Main fermentation

The main fermentation is the primary fermentation, which is mainly carried out in the fermentation bin of the waste treatment equipment. In this stage, the easily decomposable substances are decomposed under the action of microorganisms to produce carbon dioxide and water, and heat is generated to raise the stack temperature.

3. Post fermentation

Post fermentation is secondary fermentation or secondary fermentation, which can be carried out in the closed reactor of waste treatment equipment, or in the open site or silo. It is mainly to further decompose the easily decomposable organics and hard decomposable organics that have not yet been decomposed in the main fermentation process, so as to turn them into relatively stable guerrilla areas such as humic acid and amino acid, so as to obtain fully decomposed compost products.

4. Post processing

Post treatment is mainly to sort and remove plastic, glass, metal, small stones and other sundries that are not completely removed in the pre-treatment process, and then re crush them as required, or add N, P, K and other substances into the compost to produce compound fertilizer according to the soil conditions.

5. Deodorization

Odor substances mainly include ammonia, hydrogen sulfide, methyl mercaptan and amine. The removal methods mainly include chemical deodorization or biological deodorization. Chemical deodorization mainly involves chemical deodorant, filtration of alkaline water and aqueous solution, adsorption of mature compost or activated carbon, zeolite and other adsorbents. Biological deodorization is a relatively economical and practical mature compost adsorption method.

To sum up, it is the process of aerobic composting of waste treatment equipment, and I hope it can help everyone.
