AI Technical Summary
Existing wastewater treatment devices have low mixing efficiency of ozone and hydrogen peroxide, resulting in slow reaction start-up and serious ozone escape, causing waste and secondary pollution.
By employing a vortex water distributor and a two-stage jet mixer, combined with a circulating pump and an intelligent control system, uniform mixing and dynamic regulation of ozone and hydrogen peroxide are achieved, thereby improving dissolution efficiency and reducing ozone escape rate.
Accelerate the reaction start-up rate, improve oxidant utilization, reduce ozone escape rate, and achieve simultaneous optimization of mass transfer efficiency and reaction kinetics.
