Abstract

The invention discloses a tubular dielectric barrier corona discharge reaction device for a coaxial line, comprising a reactor and a power supply, wherein the reactor comprises a closed shell; the closed shell is provided with a liquid inlet and a liquid outlet and comprises a barrier dielectric tube, a base and a top cover, wherein the base is arranged on one end of the barrier dielectric tube; the top cover is arranged on the other end of the barrier dielectric tube; the barrier dielectric tube is internally provided with a fine line electrode and externally provided with an external electrode; the fine line electrode and the external electrode are electrically connected with the power supply; and the external electrode is connected to the ground. The tubular dielectric barrier corona discharge reaction device for the coaxial line has the advantages of simple structure, small size, uniform and stable discharge, low cost and good biological preprocessing effect on pharmaceutical wastewater.

Description

technical field [0001] The invention relates to the technical field of plasma discharge, in particular to a coaxial tube type dielectric barrier corona discharge reaction device. Background technique [0002] Pharmaceutical wastewater is an important source of water pollution. It often contains a wide variety of organic pollutants. Many of these organic pollutants are difficult to degrade or have inhibitory effects on microorganisms. They can remain in the environment for a long time and are extremely harmful to humans. . The existing treatment of pharmaceutical wastewater includes biofilm method, Feton oxidation technology, wet catalytic oxidation technology, ozone technology, etc. These technologies are used alone or in combination to classify or pretreat pharmaceutical wastewater, and treat certain types of pharmaceutical wastewater Good results have been achieved, but it is not universally applicable to all kinds of pharmaceutical wastewater, and most of the technologie...
