Kitchen waste mainly refers to the food waste generated by residents in daily life and food processing, catering services, unit feeding and other activities, such as leftovers, leftovers, vegetable root peels, fish bones and so on. These kitchen waste has the characteristics of high water content, high organic content, and easy to rot and produce stench. If it is not effectively treated, it is easy to cause serious pollution to the environment.

Kitchen waste

For the treatment of kitchen waste, there are many different treatment methods, such as crushing direct discharge method, sanitary landfill method, incineration power generation method, feed conversion method, anaerobic digestion method, aerobic composting method, etc., for the above kitchen waste The treatment methods have their own advantages and disadvantages and applicability. Among them, the aerobic composting method is a treatment method that is very consistent with the three principles of "harmlessness, reduction and resource utilization" of solid waste treatment.

Micron Biology is a comprehensive service provider for resource utilization and harmless treatment of kitchen waste. It has always advocated that kitchen waste should be treated by aerobic composting. The following is an introduction to the process of kitchen waste treatment by aerobic composting, that is, the application of "microbial high-temperature aerobic composting technology" in Micron Biology large kitchen waste treatment plant.

Kitchen waste disposal

The kitchen waste generated in the process of residents' daily life and catering consumption will first be collected by the staff and the kitchen waste collection and transportation vehicle to the kitchen waste treatment plant.

Kitchen waste collection and transportation

After arriving at the treatment plant, it will be weighed by the weighbridge weighing system, and then the kitchen waste will be poured into the unloading hopper. The kitchen waste in the hopper will be transported to the crusher by the shaftless screw conveyor for crushing, and then enter the biological material crushing and sorting machine for re-crushing and sorting.

Sorting

Subsequently, inorganic wastes such as plastic bags and beverage bottles are sorted out and transported for treatment, while organic wastes enter the high-pressure washing process for oil removal and salt removal. The washed organic wastes enter the dehydrator for dehydration, and then the organic solid residue enters the microbial fermentation through the inclined scraper conveyor for 1 to 2 days of microbial high-temperature aerobic fermentation. Finally, the organic wastes are converted into organic fertilizer raw materials and automatically released;

Fermentation of kitchen waste into fertilizer

In the pretreatment process, the waste liquid will enter the three-phase separation system for oil-water residue three-phase separation, and then the waste water will be discharged after treatment to the standard; the waste gas generated in the pretreatment and microbial fermentation process will be collected and discharged to the standard after treatment in the waste gas treatment system.
