[0081] Example 3 Degradation of Printing and Dyeing Wastewater by Magnetic Field Induction Photocatalytic Reactor

[0082] The actual printing and dyeing wastewater from a printing and dyeing factory in Xuzhou was selected as the degradation object, and it was photocatalytically degraded with a self-made new inductive photocatalytic reactor. Amount, H 2 o 2 The influence of factors such as the amount of dosage, the frequency of the alternating magnetic field, the magnitude of the high-frequency alternating current passing through the coil, and time on the catalytic effect. According to the experimental design, the water sample was taken from the mixed wastewater pool, which was a dark blue suspension. Due to its high turbidity, it would affect the transmission of ultraviolet light and reduce the photocatalytic reaction rate, so it was filtered before treatment. Take 125mL of actual wastewater, add a certain amount of TiO 2 and H 2 o 2 , use constant temperature circulatin...

Abstract

The present invention discloses a magnetic field inductive type photocatalytic reactor and a degradation use method therefor. The magnetic field inductive type photocatalytic reactor comprises a micro inductive light source, a reaction tank and alternating magnetic fields, wherein the micro inductive light source is arranged inside the reaction tank and the reaction tank is arranged inside the alternating magnetic fields; and the alternating magnetic fields, by means of electromagnetic induction, enable the micro inductive light source to emit light to form the inductive photocatalytic reactor of the alternating magnetic fields and optical coupling effect. The light source of a catalytic reactor can generate illumination in a reaction liquid without the need of an external power line; meanwhile, the light source has high mass-transfer efficiency in the reaction liquid and has low energy consumption and high energy efficiency.

Description

technical field [0001] The invention relates to a magnetic field induction photocatalytic reactor, which belongs to the technical field of photocatalytic reaction. Background technique [0002] Photocatalytic reaction technology is an efficient and clean wastewater treatment technology, but it has not been applied in practice, mainly because the reaction efficiency is low, which is reflected in the high recombination rate of photogenerated electrons and holes; the uneven illumination, the energy utilization rate of the light source inferior. In order to improve the quantum efficiency and energy utilization of the photocatalytic process, in addition to modifying the composition and structure of the photocatalyst (such as metal ion doping, noble metal deposition, acid modulation, surface loading and semiconductor recombination, etc.), it is also possible to To improve the photocatalytic reactor, add an external field to the photocatalytic system, including microwave field, el...
