This invention relates to the field of high-altitude environmental health monitoring technology, and particularly to an intelligent fusion analysis method and system for brain oxygen signals in high-altitude environments. This method acquires and fuses multi-channel brain oxygen saturation, multi-dimensional physiological parameters, and time-varying environmental data to mine the synergistic characteristics of oxygen metabolism across brain regions and construct a spatiotemporal evolution tensor. Based on this, a multi-scale, time-dependent hypoxia susceptibility dynamic model is constructed, generating a prospective risk assessment benchmark. Furthermore, risk extrapolation and causal chain reconstruction of brain oxygen evolution are performed, outputting structured prediction results and dynamically recalibrating the model. This achieves accurate, prospective assessment and dynamic tracking of individual brain oxygen risk in high-altitude environments.

This utility model discloses a sludge reduction device based on porous packing, belonging to the field of sludge reduction technology. It includes an inlet pipe, a reduction mechanism fixedly connected to its outer surface, a filter assembly movably connected to the inner cavity of the inlet pipe, and an outlet pipe fixedly connected inside the reduction mechanism. A valve is installed on the outer surface of the outlet pipe. Through two aerators and a stirring assembly, air can be supplied to the reaction tank to form a stable aerobic environment, providing sufficient oxygen for the aerobic metabolism of microorganisms and accelerating the decomposition of organic matter in the sludge. Simultaneously, the water flow disturbance generated by aeration and the stirring action of the stirring assembly promote full contact between the wastewater and the biofilm on the porous packing, significantly improving mass transfer efficiency. In this environment, microorganisms can more fully utilize the organic matter in the wastewater, accelerating their own metabolism and sludge decomposition, thus improving sludge reduction efficiency, effectively reducing subsequent sludge treatment costs and environmental pressure, and enhancing the practicality of the device.
