Abstract

The invention provides a sewage cavitation degradation treatment device which comprises a shell, cavitation assemblies, a rotating shaft and a driving device. The rotating shaft is installed on the shell in a sealed mode. The at least two cavitation assemblies are installed on the rotating shaft. The driving device is used for driving the rotating shaft to rotate. Each cavitation assembly comprises a stator and a rotor; the stator is fixedly installed on the inner wall of the shell, and the rotating shaft penetrates through the stator; the rotor is installed on the rotating shaft, the stator and the rotor are coaxially installed in the shell, and the end face of the stator is attached to the end face of the rotor; and a plurality of stator holes are formed in the stator, a plurality of rotor holes are formed in the rotor, the distribution positions of the stator holes in the stator are the same as the distribution positions of the rotor holes in the rotor, and the circulation area between the stator holes and the rotor holes is periodically changed through rotation of the rotor. According to the invention, domestic sewage and industrial wastewater can be treated, and fluid can be quickly treated by utilizing physical and chemical changes brought by cavitation collapse.

Description

technical field [0001] The invention relates to the field of cavitation devices, in particular to a sewage cavitation degradation treatment device. Background technique [0002] With the continuous development of modern industries such as pharmaceuticals, chemicals, printing and dyeing, the amount of sewage is increasing year by year, and the composition of pollutants is becoming more and more complex. Traditional sewage treatment methods have become inadequate. For example, physical and chemical treatment methods such as hydrolysis and photocatalytic oxidation have prominent and significant effects in the initial practice, but as the composition of pollutants becomes more and more complex, they gradually highlight some of their own defects. The hydrolysis method has the problems of large consumption of acid and alkali, and further dilution after hydrolysis consumes a large amount of water resources. Although the photocatalytic oxidation method has a high oxidation efficien...
