AI Technical Summary

Technical Problem

Existing technologies for the co-processing of straw and livestock manure suffer from problems such as lagging carbon-nitrogen ratio regulation, unclear fermentation process status, extensive control measures, and difficulty in achieving reliable online monitoring under harsh operating conditions. These issues result in low processing efficiency, unstable product quality, and poor environmental benefits.

Method used

By combining online component detection, a multimodal bio-information sensor network, personalized digital twins, and autonomous mobile actuators, dynamic closed-loop regulation of the carbon-nitrogen ratio is achieved, including local material addition, turning and tumbling operations, and differentiated oxygen supply, with precise control based on real-time monitoring data.

Benefits of technology

It achieves precise control of the carbon-nitrogen ratio, shortens the composting cycle, reduces nitrogen loss and energy consumption, improves product quality and environmental benefits, and avoids energy waste and odor emissions in the traditional static mode.

Abstract

The invention discloses a method for intelligently regulating and controlling the carbon nitrogen ratio of straw and livestock and poultry manure and efficiently decomposing the straw and the livestock and poultry manure, and belongs to the technical field of agricultural waste resourceful treatment technology and environmental engineering, and the method comprises the following steps: S1, carrying out online component detection on input straw and livestock and poultry manure, automatically mixing the materials to a preset initial carbon-nitrogen ratio based on a detection result, and inoculating a microbial agent; meanwhile, on the basis of the initial material component data, a personalized digital twinborn body of the batch of materials is constructed; the in-situ spectrum technology is used for monitoring the change of the carbon-nitrogen ratio in the pile body in real time, the unbalance trend of the pile body is predicted in combination with the digital twinborn model, the execution unit is driven to carry out local and trace material supplement adjustment, and the lag mode of traditional static matching and off-line sampling inspection is fundamentally changed. The dynamic closed-loop regulation and control can accurately control the fluctuation range of the carbon-nitrogen ratio in the whole decomposition period within + / -5, and a continuous and stable optimal nutrition environment is created for microorganisms.
