The garbage first enters the pretreatment system for automatic screening to pick out larger and harder impurities, because the recycled kitchen garbage may be mixed with glass bottles and plastic bottles. If it is not filtered first, the back-end processing equipment may be damaged. After pretreatment, the recovered kitchen waste can separate oil, water and residue, and the residue can be converted into usable resources, thus avoiding the possible threat of kitchen waste to the environment and human body, and realizing the resource and harmless utilization of kitchen waste.
After technical treatment, the waste gas and waste water produced by these wastes can completely meet the discharge standards, and the dry residue can be converted into organic fertilizer after biological fermentation, which can be used for seedling greening, soil improvement and so on. And the whole process can be clean and environmentally friendly. It is estimated that 150 tons of kitchen waste can produce 15 tons of organic fertilizer, and the waste reduction rate in the whole process can reach 90%. The fertilizer produced can be sold to landscaping companies, seedling growers and organic fertilizer factories, which can also produce good economic benefits. This is just a garbage disposal method, and different kinds of garbage have corresponding disposal methods. Environmental protection is a major and necessary project. We can start from ourselves and start from garbage sorting.
