Method and system for accurately controlling recycling of kitchen wastes according to current soil situation

Abstract

The invention discloses a method and a system for accurately controlling recycling of kitchen wastes according to the current soil situation. The method comprises the following steps: transmitting monitoring data to remote data analysis software in real time by using a soil-data remote collecting unit, establishing a model, calculating control parameters needing to be set in the treatment process of the kitchen wastes, transmitting control parameter data to a site detection control hardware so as to strictly control the conversion process of the kitchen wastes; arranging an activation reactor of mineral substances to carry out activation treatment on the minerals; and combining a high-temperature aerobiotic kitchen-waste treating system and an external-circulation non-gradient biochemical reaction unit, and monitoring the fermentation conditions at all points in a fermentation system in real time so as to carry out dynamic adjustment on the control parameters. According to the method and the system disclosed by the invention, the recycling of the kitchen wastes can be accurately controlled according to the current soil situation, the purposes of low fertilizer application amount and refined fertilizer application can be achieved, and the problems of high salinity, poor fertilization effect and unstable quality of the traditional kitchen-waste fermentation fertilizers are effectively avoided.

Description

technical field [0001] The invention relates to the technology of domestic waste treatment and reuse, in particular to a method and system for accurately controlling the resource utilization of kitchen waste according to the current soil quality. Background technique [0002] Food waste is the most important type of food waste, including food processing waste and food residues produced by families, schools, canteens and catering industries. Its components are complex, including rice, noodles, vegetables, fish, meat, bones, Oil and many other substances. Because food waste is rich in organic matter and high in water content, it is prone to decay and deterioration, produces peculiar smell, attracts mosquitoes, and is easy to breed harmful substances such as pathogenic microorganisms and mycotoxins, causing the spread of diseases and endangering human health. However, food waste has the dual characteristics of waste and resources, and the rich nutrients contained in it can be ...

AI Technical Summary

Problems solved by technology

[0003] The current resource utilization of food waste will have three types of adverse effects on the soil: First, the food waste fertilized products have high salt content, and the cumulative effect of long-term use will cause soil salinization, which is not conducive to plant growth; The second is that in the process of fertilizer conversion, improper control of temperature, pH or oxygen concentration will cause low or insufficient content of specific nutrient indicators such as available nitrogen, available phosphorus, and available potassium in the fertilizer, resulting in poor fertilization efficiency; Real-time access to soil fertility, which is likely to cause excessive fertilization and soil salinization
