Abstract

The invention discloses a dielectric barrier discharge plasma, adsorption and photocatalysis synergy waste water treatment device, which is characterized in that: an organic glass cylinder and a quartz glass tube are arranged to form a sleeve; the organic glass cylinder serves as an outer sleeve layer; active carbon fibers carrying a titanium dioxide photocatalyst are fixed on the inner side wall of the organic glass cylinder; the top part of the organic glass cylinder is provided with a water distributer capable of forming a water film on the surface of the active carbon fibers; the water in a water tank is led to the water distributor by a water pump; the quartz glass tube serves as a central tube; and a cylindrical metal electrode is arranged in the quartz glass tube to form a dielectric barrier discharge cavity. The device combines a dielectric barrier discharge plasma technique and an adsorption and photocatalysis technique to achieve a waste water treatment aim.

Description

technical field [0001] The invention relates to a waste water treatment device, more specifically a device for treating waste water with dielectric barrier discharge plasma, adsorption and photocatalysis working together. Background technique [0002] Dielectric barrier discharge is a common method to generate low-temperature plasma. It is a gas discharge in which an insulating medium is inserted into the discharge space. The medium can cover the electrodes or hang in the discharge space. When a sufficiently high voltage is applied to the discharge electrodes When the AC voltage is applied, the gas between the electrodes will be broken down even at a very high pressure to form a dielectric barrier discharge. [0003] Dielectric barrier discharge technology is currently mainly used in technical fields such as ozone production, display manufacturing, material surface treatment and modification, and gaseous pollutant treatment. In recent years, the application of dielectric ba...
