In this study, by examining the effects of the optimal carbon-nitrogen ratio and other factors on the composting effect, the optimal composting parameters of municipal sludge and kitchen waste were determined, and the carbon emissions were calculated at the same time, It had reference value for carbon neutralization and carbon peak. On the basis of reduction, harmlessness and resource utilization, a coordinated aerobic composting process for municipal sludge, kitchen waste and agricultural and forestry waste was established.
Combining the concept of "5G Internet + food safety" with the new generation of mobile Internet technologies such as Internet of things, big data, cloud computing and QR code, this paper presents an interconnected, efficient and responsive intelligent perception and response system that breaks the traditional supervision ideas and modes. This system covers the whole process of food safety and realizes the implementation of government supervision and market subject responsibilities. The comprehensive informatization of social coordination and individual participation will promote the intellectualization of food safety management, the scientization of management means and the modernization of management ability. It is an effective way to better supervise and urge the main bodies in key fields to standardize their operations and ensure food safety.
