Embodiment 1
[0030] An agricultural university currently has 30,000 teachers and students, 5-6 tons of kitchen waste per day, and the annual kitchen waste treatment cost is about 500,000. At the same time, there are problems such as food waste transfer pollution and odor drift. The school introduced the technical invention scheme in combination with the demand for organic fertilizers in the experimental farmland, and finally realized near-zero food waste discharge. At the same time, it can save 1.22 million fertilizer costs every year.
[0031] The technical solution is as follows:
[0032] S1: Preliminary cleaning is carried out in the college cafeteria to remove plastics, ceramics, metals and other debris, and the kitchen waste is collected in standard buckets and poured into the cleaning equipment uniformly, and 200 times diluted phytochemicals / biological bacteria are added. The odorant is sprayed on the surface of the kitchen waste through high pressure to achieve the effect of remov...
Embodiment 2
[0042] There are 100 industrial and mining enterprises in an iron and steel industrial park, with about 25,000 employees and about 4 tons of kitchen waste per day. Large-scale kitchen waste collection vehicles are required to collect more kitchen waste every day. During the transfer process, there are pollution and odor. And other issues. Combined with the characteristics of its own industrial solid waste, the industrial park adopts the following technical solutions to prepare organic bio-fertilizer and use it as fertilizer for plant greening in the industrial park. It can produce 1,800 tons of fertilizer and process 1,000 tons of solid waste every year. The annual saving of greening costs in the industrial park is 1.8 million yuan.
[0043] The specific technical solutions are as follows:
[0044] S1: Set up a complete set of processing equipment for kitchen and kitchen in the industrial park, collect the kitchen waste in the industrial park through transfer vehicles, pour ...
