Sewage disposal apparatus utilizing multiple-needle plate type plasma capable of discharging in both air and water

Abstract

The invention discloses a sewage disposal apparatus utilizing a multiple-needle plate type plasma capable of discharging in both air and water. The sewage disposal apparatus comprises a reactor casing, a multiple-needle plate type electrode capable of discharging in both air and liquid and a high-voltage discharge power supply. The inside of the reactor casing is divided into a discharge reaction zone and an air chamber under the discharge reaction zone; a cooling water groove used for cooling the discharge reaction zone is arranged on the periphery of the discharge reaction zone. The multiple-needle plate type electrode capable of discharging in both air and water comprises a plate type electrode and multiple hollow-needle shaped electrodes; the plate type electrode is connected to the positive pole of the high-voltage discharge power supply and the multiple hollow-needle shaped electrodes are connected to the negative pole of the high-voltage discharge power supply; the plate type electrode is arranged in the discharge reaction zone; the multiple hollow-needle shaped electrodes penetrate corresponding air micropipes fixedly arranged between the discharge reaction region and the air chamber to be arranged by corresponding to the plate type electrode. The whole sewage disposal apparatus has the advantages of high practicability, high energy utilization rate, good disposal effect, and wide application prospect in the field of sewage disposal.

Description

technical field [0001] The invention belongs to the field of water pollution purification treatment, and in particular relates to a sewage treatment device using gas-phase dielectric barrier discharge plasma. Background technique [0002] With the development of our country's economy and society, the shortage of water resources and the pollution of water environment have become increasingly prominent and become the focus of people's attention. In recent years, water pollution caused by various industrial productions has become more and more serious, the composition of sewage has become increasingly complex, and the requirements of environmental protection departments for water treatment have also been continuously strengthened. Traditional biological treatment technology has been difficult to meet the current water quality treatment requirements. [0003] Low-temperature plasma technology is an emerging advanced oxidation technology that has been utilized in the environmenta...

Problems solved by technology

[0004] Most of the existing plasma technology discharges in the air on the water surface, and then introduces the generated active particles into the water to react, which will lead to the inability of the active substances to be fully utilized. Therefore, it is necessary to design a new plasma sewage treatment device that can be used in water Directly degrade pollutants and maximize the use of active substances generated by plasma
