Abstract

The invention discloses a kitchen waste treatment method based on biotransformation. According to the kitchen waste treatment method based on the biotransformation, kitchen waste is treated through a concentrated incubation method based on a closed housing. The kitchen waste treatment method comprises the following steps: 1. charge: conveying the kitchen waste to an isolation buffering area of the closed housing; 2. pre-treatment comprising natural leaching, screening, dehydration, smashing and mixing; 3. biotransformation comprising spreading, inoculation and incubation, and larva collection; and 4. larva output, and treatment and discharge for waste materials and waste water. According to the kitchen waste treatment method based on the biotransformation, the kitchen waste is pre-treated and then conveyed to an incubation frame for raising insects to obtain maggots and an organic fertilizer, innocent treatment can be carried out on the kitchen waste, and economic benefits are achieved.

Description

technical field [0001] The invention belongs to the field of environmental protection, and relates to a technology for harmless treatment of urban garbage and a technology for resource utilization, in particular to a method for treating kitchen garbage based on biological conversion. Background technique [0002] Urban kitchen waste has the dual characteristics of environmental waste and recyclable resources. The output of food waste is large, the content of water, oil and salt is high, and it is perishable and smelly, which has become a major problem in the city. At the same time, it is rich in nutrients such as protein, starch and oil, and is a recyclable biomass resource. . At present, the treatment methods of urban kitchen waste mainly include sanitary landfill and incineration, and a small part is treated by composting. Most of the existing treatment technologies treat urban kitchen waste as urban waste, and fail to make full use of urban kitchen waste, which has many...
