PREPARATION METHOD OF KITCHEN WASTE CARBON-BASED COMPLEX ENZYME
BIOLOGICAL BACTERIAL FERTILIZER
The invention relates to the technical field of garbage treatment, in particular to a preparation method of a kitchen gar- bage carbon-based complex enzyme biological bacterial fertilizer.
Background Technology
Kitchen waste is a kind of organic waste, which is mainly food residues, food processing waste and waste gas edible oil pro- duced by relevant enterprises and public institutions in food pro- cessing, catering services, unit meals and other activities. It has the characteristics of large output, relatively concentrated quantity but wide distribution.
In terms of chemical composition, kitchen waste includes starch, cellulose, protein, lipids, inorganic salts and water, which are rich in nutrients and can be decomposed by microorgan- isms in nature. It is usually treated by aerobic composting, mi- crobial degradation and organic fertilizer. Therefore, a method is needed to treat kitchen waste and make it into fertilizer.
At present, the common treatment methods of kitchen waste are aerobic composting and anaerobic digestion, in which aerobic com- posting is mainly to degrade the organic matter in kitchen waste through aerobic microorganisms under aerobic conditions, so as to obtain high-fertility humus with high stability, but this method has high requirements for the site, and also produces a lot of odor. Because of the high content of salt in the kitchen waste, if the kitchen waste is treated by this method for a long time, the soil salinization will be aggravated, and a large amount of salt and grease in the kitchen waste will also inhibit the growth of microorganisms, resulting in the decline of the quality of com- posting products and the extension of the cycle.
Anaerobic digestion is mainly through the metabolic reaction of facultative anaerobic microorganisms to decompose the organic matter in the waste in an anaerobic environment, so as to obtain simple small molecular inorganic matter and organic matter. Anaer- obic digestion treatment also has the problem of high salt and oil content, which will lead to excessive alkalization, high pH value in the digestion process and inhibit the growth of bacteria. It is not conducive to the continuous and stable degradation of kitchen waste, at the same time, the biogas residue produced by anaerobic fermentation needs further treatment, usually needs to be land- filled after drying treatment, or made into organic fertilizer af- ter re-composting.
Biological bacterial fertilizer is an organic fertilizer con- taining beneficial bacteria, which can not be replaced by chemical fertilizer in improving soil and improving the "physique" of trees.
