AI Technical Summary
Existing catalytic-ultrasound synergistic technology for treating formaldehyde in industrial wastewater suffers from several drawbacks. These include the inability of a single-dimensional partition design to accurately adapt to concentration gradients, low efficiency of cavitation response mode, lag in the control system response, weak resistance to shocks, and inability to adapt to extreme working conditions. Consequently, the formaldehyde degradation efficiency is unstable, energy consumption is high, and the scope of application is limited.
The catalytic-ultrasonic synergistic system, which adopts a dual-zone design, combines dual-drive cavitation synergy, intelligent closed-loop control, and unit-integrated synergistic mode. It uses a 3×2 dual-zone catalyst tube array and acoustic focusing module, equipped with an independent micro piezoelectric drive mechanism and catalytic coating. It uses a PLC controller to achieve intelligent control, and with the help of circulation cooling and enhanced backwashing modules, it achieves targeted degradation of formaldehyde.
It achieves precise degradation of formaldehyde wastewater with different concentrations, improves degradation efficiency and stability, reduces energy consumption, expands the scope of application of the process, and ensures the stability of effluent concentration and equipment life.
