AI Technical Summary

Technical Problem

Existing wastewater treatment equipment struggles to simultaneously treat suspended solids and microorganisms under high turbidity conditions, and it is energy-intensive. Traditional bubble treatment is inefficient and cannot meet the demand for high-efficiency purification.

Method used

A high-temperature CO2 micro-nano bubble system is used to heat CO2 gas to 150-600℃ through a heating device. Nanoscale bubbles are generated by a drive motor and ceramic membrane. Combined with a transient thermal layer and CO2 chemical permeation, it can efficiently inactivate microorganisms and remove suspended solids.

Benefits of technology

It significantly improves gas-liquid contact efficiency, rapidly inactivates harmful microorganisms in wastewater, removes suspended solids, reduces energy consumption, and achieves compliant discharge of purified water.
