Abstract

The invention discloses a vegetable waste composting technology. According to the invention, sludge particles are combined with rapeseed shells. With the intrinsic nutrients in the sludge, the defect of the assistances of inorganic fertilizers such as urea and phosphate fertilizer for fermentation of a traditional waste vegetable composting process is solved. Also, with the loose and air-permeating characteristics of rapeseed shells, the technical difficulty of the need of a ventilation well for solving the problem of necessary oxygen during the waste vegetable composting and degrading process in traditional processes is solved. Therefore, the problem of waste vegetable processing is solved, and green production of the compost product is realized. Composting cost is greatly reduced, operation complicity is reduced, and high practicality is shown.

Description

technical field [0001] The invention relates to a composting method of organic waste, in particular to a composting process of vegetable waste. Background technique [0002] With the rapid development of my country's economy and the improvement of people's living standards, vegetables, as one of the main sources of vitamins and minerals necessary for the human body, are in increasing demand. Due to strict vegetable production technology, high product commercialization rate, and relatively harsh storage environment of vegetables, vegetable production is characterized by scale, mechanization, and centralization. The above-mentioned status quo will inevitably lead to concentration of vegetable waste, and random stacking and dumping. Because vegetable waste contains high moisture, it is easy to generate odor and sewage during its decomposition process. If it is not added to the treatment, it will be allowed to accumulate in large quantities, and it will easily rot and become sme...
