Embodiment 1
[0032] see figure 1 , the present embodiment provides a rapid degradation in-situ treatment process for kitchen waste, which includes the following steps:
[0033] (1) Automatic feeding and weighing
[0034] The food waste is weighed in real time through the remote weighing sensor, and the food waste is automatically fed to the next step through the automatic hoist; among them, the weighing data of the food waste is transmitted to the food IoT monitoring platform.
[0035] (2) Sorting and crushing
[0036] Sorting and separating the domestic waste and leachate in the kitchen waste, and breaking the separated domestic waste into particles with a diameter of 10-30mm; among them, when sorting the domestic waste, it can be sorted manually (such as the existing Garbage classification processing method) plastic products, instant noodle boxes, cans, glass bottles, dishes, spoons, chopsticks and other domestic waste; and the sorted materials can be crushed by a crusher. Of course, ...
Embodiment 2
[0048] see figure 2 , this embodiment provides a fast-degradation in-situ treatment system for food waste, which applies the fast-degradation in-situ treatment process for food waste in Example 1, and the fast-degradation in-situ treatment system for food waste includes an automatic feeding subsystem, Sorting subsystem, crushing subsystem, mixing and dehydration subsystem, biodegradation subsystem, oil-water ionization system, deodorization and sterilization subsystem and detection system.
[0049] The automatic feeding subsystem is used to transport food waste to the sorting subsystem. The automatic feeding subsystem may include an automatic elevator, a storage box, a feeding switch, a feeding controller, and a weight detection device. Wherein, the automatic elevator in this embodiment is used to transport food waste to the sorting subsystem. There may be multiple storage boxes, and the multiple storage boxes are respectively set in the kitchens of multiple users to collect...

Abstract
The invention discloses a fast degradation on-site treatment process for kitchen garbage. The process comprises the following steps: domestic garbage and a percolate in the kitchen garbage are sortedand separated, and the separated domestic garbage is crushed into particles with diameter of 10-30 mm; the particles are stirred, and the stirred particles are squeezed and dewatered, so that the water content is 40%-60%; various enzymes are produced by microbial degradation bacteria so as to biodegrade kitchen waste in the squeezed and dewatered particles and produce organic fertilizer for recycling; the sorted and separated percolate, dilution water produced by crushing and liquid produced by squeezing and dewatering are mixed into a mixed solution, electrolysis, air floatation, hydrolytic acidification and biochemical process treatment are performed on the mixed solution for oil-water separation of the mixed solution, so that waste water produced by oil-water separation meets the discharge standard, and oil produced by oil-water separation is recycled. Residual value of the kitchen garbage can be fully utilized, the transportation cost is saved, and the kitchen garbage is rapidly degraded in time.
Description
technical field [0001] The invention relates to a kitchen waste treatment process in the technical field of kitchen waste treatment, in particular to a fast degradation in-situ treatment process for kitchen waste. Background technique [0002] Kitchen waste is the main part of daily life waste, accounting for more than 60-80% of municipal solid waste. Because food waste is perishable, it leads to the breeding of mosquitoes and flies in the landfill, the stench is unpleasant, and the pollution caused to the air and water is difficult to control. The organic components contained in it are becoming more and more harmful to the environment and public health. [0003] However, the existing food waste treatment method is centralized treatment, which is mixed with domestic waste for collection, classification, transportation, and centralized disposal. However, food waste is processed together with other domestic waste, which wastes part of the recycling and reuse of food waste. va...
