Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a device for efficiently treating sewage by using cavitation effect. Background technique [0002] The shortage of water resources has become an important factor that seriously plagues economic development and the improvement of people's living standards. The main reason for my country's water shortage is that water resources are seriously polluted. The key to its governance is to treat various industrial wastewater and domestic sewage. Due to the continuous increase in the output and types of organic compounds, it is particularly important to use effective purification processes to remove various pollutants under the current increasingly higher environmental protection requirements. As a new physical and chemical water treatment technology, cavitation technology has received more and more attention. When cavitation bubbles collapse, they can generate high te...

Problems solved by technology

Cavitation mainly includes ultrasonic cavitation and hydraulic cavitation, but the sonochemical reaction efficiency of the two types of cavitation is low

Existing research and patent achievements have adopted combined technology to enhance the effect of cavitation water treatment. Cavitation is integrated with other technologies such as catalysis, oxidation, and membrane separation to achieve water treatment effect, and the cavitation unit has not been improved. cavitation efficiency

Moreover, none of the existing hydraulic cavitation devices can realize online detection of water quality and automatic control on this basis, resulting in inconvenient operation, low degree of automation, and poor water treatment effect, which in turn affects the performance of the hydraulic cavitation device. , and limit the further popularization and application of hydraulic cavitation technology
