Example Embodiment

[0022] In the following, the present invention will be further described in conjunction with the drawings and specific implementations. It should be noted that, provided that there is no conflict, the following embodiments or technical features can be combined to form new embodiments. .

[0023] See figure 1 , The embodiment of the present invention provides a waste fermentation process S10, including the following steps:

[0024] In a sorting step S11, the garbage is sorted by a sorting mechanism, and the garbage containing 15%-20% insoluble organic matter is sorted out;

[0025] Natural fermentation step S12, natural fermentation of the garbage containing 15%-20% insoluble organic matter to obtain fermentation intermediate products;

[0026] In the biological fermentation step S13, a spray containing probiotic strains is added to the fermentation intermediate product to perform biological fermentation to obtain organic fertilizer.

[0027] Among them, in the one-time sorting step S11...

Abstract

The invention discloses a garbage fermentation process. The method comprises the following steps of primary sorting, wherein a sorting mechanism is adopted for sorting garbage, and garbage containing15-20% of non-soluble organic matter is sorted out; natural fermentation, wherein the garbage containing 15-20% of non-soluble organic matter is subjected to natural fermentation to obtain a fermentation intermediate product; bio-bacterial fermentation, wherein a spraying agent containing probiotic cultures is added into the fermentation intermediate product for bio-bacterial fermentation to obtain organic fertilizer. According to the garbage fermentation process, the garbage cannot get caked and become mud in the fermentation process, which is beneficial for fermentation of the garbage, and organic matter in the garbage can be effectively reserved and increased, so that the quality of the organic fertilizer generated by garbage fermentation is high.

Description

technical field [0001] The invention relates to the field of garbage treatment, in particular to a garbage fermentation process. Background technique [0002] With the rapid development of China's economy, the number of cities and population have increased significantly, and the scale and scope of cities have continued to expand. In the process of accelerating urbanization, the output of municipal solid waste has also continued to increase, and among these municipal solid waste More than 50% of it is meal waste, which contains relatively rich organic matter. How to recycle these domestic wastes is a major issue in the field of waste treatment. resources in an efficient manner. [0003] At present, in China, the conversion of garbage into organic fertilizers is generally carried out by medium-high temperature anaerobic fermentation. The fermentation temperature is above 100°C. This fermentation temperature easily destroys the organic matter of the fertilizer, resulting in th...
