High-pressure atomizing dielectric barrier discharge plasma water treatment device

Abstract

The invention relates to a high-pressure atomizing dielectric barrier discharge plasma water treatment device which comprises a sewage treatment cavity and a discharge reaction chamber, wherein a sewage outlet II is formed in the side wall of the sewage treatment cavity, and a dosing device for feeding ferrous sulfate into the sewage treatment cavity and a gas outlet are arranged in the top wall; the sewage outlet II is communicated with one end of a sewage pipe I; an array type high-pressure atomizing spray head is arranged at the other end of the sewage pipe I and positioned at the top of the discharge reaction chamber; a high-pressure water pump is arranged on the sewage pipe I; a fan for blowing the high-pressure atomized sewage into the discharge reaction chamber is arranged at the top of the discharge reaction chamber, and the bottom is communicated with a gas-liquid mixture inlet of a gas-liquid separator; the gas-state substance (mixture of air and ozone) and liquid-state substance (sewage and hydrogen peroxide) separated by the gas-liquid separator are fed into the sewage treatment cavity respectively. The device provided by the invention makes full use of the incomplete-reaction strong-oxidizing substances, increases the contact area between sewage and plasma, improves the sewage treatment efficiency and reduces the operation cost.

Description

technical field [0001] The invention belongs to the field of plasma water treatment, in particular to a high-voltage atomization dielectric barrier discharge plasma water treatment device. Background technique [0002] Water is an important material for the survival of human beings and all living things, and it is also an irreplaceable precious natural resource for industrial and agricultural production and economic development. However, with the acceleration of industrialization and urbanization in modern society, the amount of sewage discharge has increased sharply, and the problem of water pollution has become one of the problems that countries all over the world are facing. According to statistics, more than 25 million children in the world die from drinking polluted water every year; 1.2 billion people suffer from various diseases due to drinking polluted water; cholera, dysentery and malaria caused by water pollution all over the world The number of people with such i...

Problems solved by technology

This method not only has a good decomposition effect on high-concentration organic pollutants, but also can decompose large-flow and low-concentration pollutants. However, the processing capacity per unit time of domestic and foreign plasma water treatment devices is small, and it is difficult to realize industrialization. application problem
