Abstract

The invention discloses a water spray discharge air plasma jet processing device and a high-voltage power source thereof. Water to be treated is atomized into a fine mixture of water drops and air at first; consequently, the collision frequency of active particles generated by discharge with toxic and harmful species in water is effectively improved in the discharge reaction processing process, the chemical reaction rate can be effectively increased, the water-air mixing ratio of the water spray jet and the flow velocity of the water spray jet can be adjusted, the chemical reaction kinetics of the water spray jet generated in an atomization reactor are adjusted, the highest efficiency and the most energy-saving state of running of the water processing system are realized, and the processed water is subjected to circulating treatment a plurality of times so that the requirement of emission can be met at last; a voltage and current detection circuit for the input end and the output end of the high-voltage power source is capable of effectively determining whether the system runs normally; therefore, the optimal running parameter control of the water processing system between physical parameters such as the discharge power of the output end, the water spray jet speed and the water-air mixing ratio, and the water processing effect is realized.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a water mist discharge air plasma jet treatment device and a high-voltage power supply thereof. Background technique [0002] Traditional wastewater treatment devices can no longer meet the increasing discharge standards and treatment efficiency. For example, patent CN102344217 discloses a plasma and ultrasonic integrated sewage treatment device, which combines the characteristics of high temperature and high pressure of ultrasonic technology with strong shock waves and electrical technology Combining high-energy electron bombardment, ozonation, ultraviolet photolysis and other technologies of plasma formed by corona discharge to comprehensively treat sewage, the effect on high-concentration refractory organic waste water is obvious. However, the device consumes a lot of energy, has high operating costs, and does not make full use of the degradation function of the p...
