Micro-hollow cathode discharge plasma efficient sewage treatment unit

Abstract

The invention relates to a micro-hollow cathode discharge plasma efficient sewage treatment unit, which structurally comprises a reactor, an air supply system, a high-voltage power supply and a sewage tank, wherein the reactor carries out high-voltage atomization cathod discharge reaction treatment to the sewage; the air supply system is connected with the reactor through a pipeline, and providesthe injection airflow for the reactor; the high-voltage power supply is connected with the reactor, and provides the energy which is required by the discharge of the high-voltage cathod discharge reaction of the reactor; and the sewage tank is connected with the reactor through the pipeline, and provides the sewage to be treated for the reactor. The micro-hollow cathode discharge plasma efficientsewage treatment unit can treat domestic wastewater and industrial sewage, during the sewage treatment process, no chemical additives are required to be added, the treatment process is simple and hasno waste, and the control and automation are easy to realize; and the electron density of micro-hollow cathode discharge is high, the working efficiency is high, and the electrode loss is small.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a micro-hollow cathode discharge plasma high-efficiency sewage treatment device. Background technique [0002] At present, the discharge of industrial pollutants is increasing, and the environmental pollution is becoming more and more serious. In particular, the pollution of water resources, which is closely related to human life, is becoming more and more serious, and there are more and more toxic and harmful substances (such as chlorophenols, polychlorinated biphenyls, etc.) in water. These harmful substances are affecting human health through the food chain or drinking water, causing people to produce a variety of diseases, such as inducing carcinogenic, teratogenic, and mutagenic effects. [0003] Conventional methods for sewage treatment mainly include biological methods, physicochemical methods, and oxidation methods, etc., but these treatment methods are ineffective and costly...

AI Technical Summary

Problems solved by technology

The shortcomings of the electron beam irradiation water treatment method are that the manufacturing process of the electron gun is complicated and the precision is high; the surface area of ​​the water body irradiated by the electron beam is limited, which affects large-scale sewage treatment

The shortcomings of the pulse discharge water treatment method are that the pulse high-voltage power supply technology for industrial applications is difficult, resulting in high manufacturing costs; the pulse discharge process is greatly affected by the conductivity of the treatment solution; the high-voltage discharge electrodes are severely corroded, affecting water quality. stable operation of the process

The disadvantage of the dielectric barrier discharge water treatment method is that because the discharge is generally pulsed, the time duty ratio is small, which affects the efficiency of sewage treatment

Due to the shortcomings of the above-mentioned water treatment methods, the application of sewage treatment devices has been greatly restricted
