Description

technical field [0001] The present invention relates to a cascade water treatment device combining plasma, ultrasound and catalysis, in particular to a cascade water treatment device combining plasma, ultrasound and catalysis, as well as its single-stage circulation device and multi-stage series device. It belongs to the technical field of water treatment. Background technique [0002] The plasma jet generated by high-voltage discharge is rich in high-energy electrons, ultraviolet (UV), shock waves, ozone and active particles (OH, O, H, O 3 、H 2 o 2 etc.), this feature can be used to remove toxic species such as refractory organic matter, bacteria, and heavy metals in water. Ultrasound has special physical and chemical effects in wastewater degradation, especially the local high temperature (greater than 5000K) and high pressure (greater than 100MPa) produced by ultrasonic cavitation, which provides an extreme physical and chemical environment for the chemical reaction of...
