Problems solved by technology

Food waste has high organic matter content, large output, is easy to be corrupted, sour and smelly, and breeds harmful organisms. If leakage occurs during collection and transportation, it will pollute air, soil and water sources, and seriously interfere with people's normal life; especially in summer, if the day If it is not cleaned, it will rot, deteriorate and smell, producing a variety of harmful pathogenic microorganisms and polluting the environment
[0003] At present, the commonly used food waste treatment technologies at home and abroad include incineration, sanitary landfill, ecological feed, anaerobic digestion, aerobic composting and vermicomposting, etc., and foreign countries have formed a mature environmental protection industry for the resource treatment of food waste. It is still in its infancy in China, and in the recycling of food waste, there are usually defects of low resource utilization efficiency and unsatisfactory economic benefits
When incinerated, food waste not only has low thermal efficiency, but also produces toxins that pollute the environment

Abstract

The invention relates to a fermenting agent for producing a feed from food waste. The fermenting agent comprises the following raw material components of trichoderma koningii, bacillus subtilis, candida utilis and spirulina in the mass ratio of the trichoderma koningii to the bacillus subtilis to the candida utilis to the spirulina being (1-2) to (5-8) to (0.5-1) to (5-10). The application of thefermenting agent to production of the feed from the food waste comprises the following steps of mixing the food waste with calcium oxide and green alga powder, adding the fermenting agent for fermentation, performing mixing with nutrient substances, performing sterilization, performing granulation and performing drying to obtain the feed. The fermenting agent provided by the invention is adopted,so that feed products can be harmless, the produced feed is used for raising aquatic animals, the application safety of the food waste as the feed products can be guaranteed, and the quality requirements of markets for the feed products can be met.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a starter for producing feed from food waste and its application. Background technique [0002] Food waste refers to the perishable garbage produced by people in the process of buying, selling, storing, processing and eating various foods; it covers all food-related waste, including kitchen waste, slops, food waste content. As the main component of municipal solid waste, food waste accounts for about 50% of municipal solid waste. According to the current per capita generation of urban domestic waste at 1 kg per person per day, a city with a population of 1 million will generate about 1,000 tons of organic waste per day, and the annual amount of organic waste will be as high as 360,000 tons. According to research, food waste has the characteristics of high moisture, high salinity, high organic matter content, obvious temporal and spatial differences in components, and ...
