Abstract

The invention discloses a high-frequency-pulse non-equilibrium plasma sewage treatment device. The high-frequency-pulse non-equilibrium plasma sewage treatment device comprises a rectifying and filtering device, a high-frequency inversion device, a control and protection device and a pulse output device, wherein the rectifying and filtering device is used for firstly rectifying and filtering the input single-phase alternating current into direct current; then the high-frequency inversion device is used for obtaining high-frequency alternating pulse; high-frequency narrow pulse is output by the pulse output device; the control and protection device is used for sending a driving signal to control the high-frequency inversion device to act. According to the high-frequency-pulse non-equilibrium plasma sewage treatment device, the high-frequency narrow pulse can be used for greatly overcoming the defects of high energy consumption, low efficiency and high cost of the original direct-current electrolytic sewage; by virtue of the high-frequency-pulse non-equilibrium plasma technology, electric ions generated by discharging direct generate degradation reaction with organic matters in the sewage; the device is high in sewage removal efficiency and small and exquisite in appearance; the original sewage treatment device is convenient to mount and improve.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and relates to special equipment for sewage treatment, in particular to a high-frequency pulse unbalanced plasma sewage treatment device. Background technique [0002] Printed Circuit Board (PCB) wastewater can generally be divided into cleaning wastewater, ink wastewater, complex wastewater, concentrated acid wastewater, concentrated alkali wastewater and other wastewater types according to the main pollutants. The ink wastewater It mainly comes from the processes of screen printing, development, and film stripping in the production process of circuit boards. [0003] PCB ink wastewater is a kind of high-concentration organic wastewater, its CODcr is usually 5000~10000 mg / L, some can be as high as 20000mg / L, SS is about 800~1200mg / L, the pH value is generally alkaline, and the color of the wastewater is Dark blue, this type of wastewater accounts for about 5% of the total PCB wastewa...
