Fruit and vegetable waste and kitchen waste cooperative treatment process

Abstract

The invention relates to a fruit and vegetable waste and kitchen waste cooperative treatment process. The fruit and vegetable waste and kitchen waste cooperative treatment process comprises the stepsof fruit and vegetable waste pretreatment, kitchen waste pretreatment and cooperative treatment; at first, fruit and vegetable wastes are pretreated and kitchen wastes are also pretreated to obtain fruit and vegetable waste slurry and kitchen waste slurry, the two slurries are mixed and are treated cooperatively, and an amino acid liquid manure and humus wastes are formed by fermentation. The fruit and vegetable wastes are pretreated to form the fruit and vegetable waste slurry, the kitchen wastes are pretreated to form the kitchen waste slurry, then the fruit and vegetable waste slurry and the kitchen waste slurry are mixed at a certain ratio, thus, microorganisms are decomposed in a liquid environment, in the liquid environment, the diffusion and reproduction speeds of cultures are the highest, the reaction speed is high, and thus, the fermentation period of the fruit and vegetable wastes is shortened.

Description

technical field [0001] The invention relates to the field of organic waste treatment, in particular to a collaborative treatment process for fruit and vegetable waste and kitchen waste. Background technique [0002] Most of the food waste in the existing industry is treated by aerobic composting or anaerobic biogas production. Due to the high investment cost, it is only suitable for large-tonnage treatment projects, and it is not suitable for small-scale projects. Moreover, if it is pure fruit and vegetable waste, The protein content is not high, the organic fertilizer or biogas output is very little, and the economy is very poor. However, if the fruit and vegetable waste is directly mixed with the kitchen, it will easily cause stench and the fermentation cycle will be long. [0003] In view of this, the inventors conceived deeply on many problems existing in the treatment of fruit and vegetable wastes, and then developed the present invention. Contents of the invention ...
