Ultrasonic pesticide wastewater degradation device with variable reaction volume

Abstract

The invention discloses an ultrasonic pesticide wastewater degradation device with variable reaction volume. The device comprises a reaction container, a liquid level switch, a controller, a multi-path switching switch component, a drive isolation module, a power amplification module, an impedance matching transformer, an ultrasonic signal generation module, a matching inductor and a plurality of energy converters, wherein the reaction container is provided with a reaction tank; the signal output end of the liquid level switch is connected with the controller and is arranged in the reaction tank; the energy converters are arranged on the reaction container and are arranged along the liquid level fluctuation direction side by side; the output end of the ultrasonic signal generation module is connected with the drive isolation module; the output end of the drive isolation module is connected with the power amplification module. By the ultrasonic pesticide wastewater degradation device with the variable reaction volume, pesticide wastewater degradation under different volumes can be met, moreover, the degradation capacity is also high, meanwhile, the damage of the energy converters caused by excessive heating can be prevented, and the cleaning degradation of pesticide wastewater is accelerated.

Description

technical field [0001] The invention relates to an ultrasonic pesticide wastewater degradation device with variable reaction capacity, belonging to the field of ultrasonic pesticide wastewater degradation. Background technique [0002] At present, the extensive use of traditional chemical pesticides has caused serious global environmental pollution and ecological damage. In recent years, with the improvement of people's living standards, the problems of environment and ecological balance have been paid more and more attention. How to eliminate pesticide residues in the environment has become a research hotspot all over the world. At present, the pesticide residue degradation methods in the world mainly include: [0003] 1. Traditional physical methods such as adsorption, washing and irradiation. This method has insufficient degradation and removal effect on low-concentration residual pesticides, is labor-intensive, consumes a lot of water, and there is a secondary pollutio...

AI Technical Summary

Problems solved by technology

Although there have been related studies on the application of ultrasound to the degradation of pesticide wastewater, most of them are qualitative analysis of the degradation of different concentrations of different types of pesticide wastewater by ultrasound under a certain fixed volume, and there are complex structures, fixed conditions, and low degradation efficiency. The volume of treated wastewater is not variable, etc.
