Independent-aeration high-voltage pulse discharging water treatment reactor and sewage treatment method thereof

Abstract

The invention discloses an independent-aeration high-voltage pulse discharging water treatment reactor and a sewage treatment method thereof. The independent-aeration high-voltage pulse discharging water treatment reactor comprises at least one high-voltage pulse discharging reactor and at least one independent aeration device lower than the high-voltage pulse discharging reactor. According to the invention, O3 generated through high-voltage pulse discharging can be utilized more effectively for sewage treatment, meanwhile, pulse actions generated by a peristaltic pump can be effectively overcome, in addition, a porous titanium substrate is applied to an electrode of the high-voltage pulse discharging reactor, so that not only is the role of the electrode played, but also the purposes of aeration, liquid distribution, pulse inhibition and catalysis are achieved.

Description

technical field [0001] The invention belongs to the application of low-temperature plasma technology in the field of environmental pollution control, and specifically relates to a device and method for generating highly active chemical substances in both gas-liquid phases of a reactor under the action of high-voltage pulse discharge to degrade organic pollutants in water. Background technique [0002] With the expansion of people's production and living activities, the process of industrialization is getting faster and faster, and the pollutants in petroleum, printing, metallurgy, leather, dyes and other industries have increased greatly, which has brought serious water environmental pollution problems, and this kind of The pollution affects a large area, and the pollutants produced usually have the characteristics of high biochemical oxygen demand, high chroma, high pH value, refractory biodegradation, high concentration, complex composition, and biological toxicity.

Problems solved by technology

[0004] Existing studies on various types of high-voltage pulse reactors have confirmed that the introduction of air or oxygen into the reactor is conducive to the generation of more active particles in the discharge, and one of the most active species in this reactor is O 3 , but the utilization of ozone in existing reactors is still not high enough

In addition, in high voltage pulse discharge with TiO 2 In the study of catalytic synergy, TiO is usually 2 Nanoparticles are put into the discharge reactor, but this is not good for TiO 2 separated from the solution, while the TiO 2 There is also TiO in the form of supported on activated carbon, activated carbon fiber, PET, glass and other substrates 2 The film is easy to break and fall off, etc.
