Embodiment 1

[0016] Embodiment 1: In order to meet the treatment requirements of difficult-to-degrade soil organic matter, the present invention proposes an azo dye chemical waste liquid composition analysis device.

[0017] Acquisition device, matching device, query device, pulse discharge device, high pressure reactor, liquefaction device, indicator, explosive device, oxidation device;

[0018] In order to reduce the cost and facilitate the observation of the discharge phenomenon, the high-pressure reactor is made of transparent plexiglass, and the liquefaction device is made of small stainless steel. The pulse discharge device is used to perform a more uniform gas and liquid two-phase discharge process in the liquefaction device. The indicator is used to study the degradation effect of the high-pressure reactor on the azo dye chemical waste liquid, and it is shown whether the use of a pulse discharge device can effectively degrade the indicator in the azo dye chemical waste liquid.

Embodiment 2

[0031] Embodiment 2: The hollow discharge electrode designed by the pulse discharge device can also be used as a channel for the azo dye chemical waste liquid to be processed into the high pressure reactor, so that the azo dye chemical waste liquid to be processed passes through the hollow high pressure discharge The electrode is atomized into small droplets by the liquefaction device. During the explosion process of the internal pulse discharge, the vicinity of the hollow high-voltage discharge electrode is the area with the highest discharge plasma density. A large number of active particles that can interact with pollutants gather here. The azo dye chemical waste liquid to be processed will greatly Increases the probability of pollutants and active particles; on the other hand, the azo dye chemical waste liquid to be treated is atomized into small droplets under the action of electrostatic force and surface tension, and the surface area increases, which also increases The pr...

Description

Technical field [0001] The invention relates to a chemical waste liquid treatment field, in particular to a high-efficiency chemical internal pulse discharge explosion control system. Background technique [0002] Azo dye chemical waste liquid is a refractory industrial chemical. With the rapid development of the dye industry, a large number of azo dye chemical waste liquids with high chroma, complex components, high chemical oxygen demand, and poor biodegradability are discharged into the water body, causing serious pollution. At present, traditional physical and biochemical methods are not ideal for treating such azo dye chemical waste liquids. Therefore, it is of great practical significance to adopt the pulse internal pulse discharge explosion technology and analyze and treat the composition of the azo dye chemical waste after the pulse discharge explosion. Summary of the invention [0003] The purpose of the present invention is to solve the above problems by providing an a...
