AI Technical Summary

Technical Problem

Existing livestock wastewater sterilization treatment devices have unstable sterilization effects when water quality fluctuates, and there are problems with excessive consumption of energy and chemicals. They also lack a coordinated linkage mechanism, resulting in a lag in response mechanism and insufficient control precision.

Method used

A device comprising a filter housing, a mixing sterilization tank, a vortex generation chamber, an ultraviolet catalytic sterilization chamber, and an ozone contact reaction chamber was designed. Combined with a control system, the ozone aeration rate is optimized in real time through an emergency assessment model and an aeration rate control module to ensure that all units work together and adapt to water quality fluctuations.

Benefits of technology

It achieves stable sterilization effect under water quality fluctuations, reduces energy and chemical waste, enhances the device's resilience and operational reliability, and improves overall sterilization efficiency.
