Immersed sewage treatment device

Abstract

The invention discloses an immersed sewage treatment device which comprises a reactor, a circulating pump and a protective cavity, a discharge plate is arranged on one side of the reactor, a first polarity sleeve and a second polarity sleeve are arranged on any side of the discharge plate, and a conversion cavity is formed in the side, connected with the protective sleeve, of the polarity end of the first polarity sleeve and the polarity end of the second polarity sleeve. One side of the protective cavity is communicated with the protective cavity, and one side of the protective cavity is communicated with a drainage pipe and a circulating pipe; a starting square power supply is arranged, under the action of the starting square power supply, multiple molecules such as oxygen and water in air in a discharge area can be excited to generate a large number of active substances such as OH, eeq, HO2 and O3, and ultraviolet light and visible light can also be generated; gas in the circulating pump and the circulating reactor enters reaction liquid through a top aeration hole and a circulating pipe which are arranged on the top cover and the side surface of the protective cavity; and gas passing through the top aeration holes blows positive ions generated in the discharge area into the to-be-reacted liquid.

Description

technical field [0001] The invention relates to the technical field of environmental protection treatment, in particular to an immersion-based sewage treatment device. Background technique [0002] With the continuous development of economy and society, the environmental problems of water bodies have become increasingly prominent and serious. Many refractory pollutants are discharged into water bodies, causing the accumulation of these substances in water bodies, which seriously threatens aquatic ecosystems and human health. Traditional biological treatment technologies are difficult to meet Increasingly complex water quality treatment requirements, such as the treatment of dye wastewater, pesticide wastewater, wastewater containing persistent organic pollutants, etc. [0003] Cationic body technology is a relatively cutting-edge advanced oxidation technology that has emerged in recent years, and was first applied to environmental governance. It has multiple functions such a...

AI Technical Summary

Problems solved by technology

[0004] Most of the cation sewage treatment devices currently developed have some problems more or less, such as the inability to discharge efficiently in the water phase, and the inability to efficiently generate cations. The body cannot be fully utilized, and cannot be fully mixed and reacted with the water body in time; in addition, the ozone generated during the discharge of the cationic body cannot be fully utilized, and it is discharged into the air to pollute the environment; some other reaction devices require magnetic stirring or mechanical stirring, which consumes energy larger
