Molecular-level dense-phase rectification magnetic coupling oxygen dissolving device and ecological activity restoration system

Abstract

The invention discloses a molecular-level dense-phase rectification magnetic coupling oxygen dissolving device, and relates to the technical field of river water treatment and ecological restoration,the molecular-level dense-phase rectification magnetic coupling oxygen dissolving device comprises a reactor tank body, a water inlet pipe and a water outlet pipe, the molecular-level dense-phase rectification magnetic coupling oxygen dissolving device further comprises a dissolved oxygen introducing assembly which is used to magnetize water in the tank body and then introduce micro-nano bubbles with set sizes, a dissolved oxygen concentration increasing assembly which is used to cut the micro-nano bubbles introduced into the tank body, a dissolved oxygen concentration monitoring assembly which is used for monitoring the dissolved oxygen concentration of the water in the water outlet pipe and outputting a concentration monitoring signal, a control assembly which is in signal connection with the dissolved oxygen introducting assembly, the dissolved oxygen concentration increasing assembly and the dissolved oxygen concentration monitoring assembly, receiving and responding to the concentration monitoring signal and outputting a control signal to control the dissolved oxygen introducing module and / or the dissolved oxygen concentration increasing module to act, so that the generated supersaturated dissolved oxygen water is uniformly distributed into the riverway through a water distribution pipeline, the bottom mud and riverway microenvironment are conditioned and improved, and thewhole system is converted from an anaerobic state to an aerobic state.

Description

technical field [0001] The invention relates to the technical field of river channel water treatment and ecological restoration, more specifically, it relates to a molecular-level dense-phase rectification magnetically coupled dissolved oxygen device and an ecologically active restoration system. Background technique [0002] Dissolved oxygen (dissolvedoxygen) content is the most important comprehensive index to measure the water quality of rivers. On the one hand, the relatively advanced aquatic organisms in the river need a certain amount of dissolved oxygen to survive; on the other hand, the lack of oxygen in the river will lead to the reproduction of anaerobic bacteria, and the water quality will deteriorate sharply, making the river black and smelly. [0003] In order to increase the dissolved oxygen content in the river water body, the most simple and direct method is to aerate the river water body with oxygen. For example, the Chinese patent with the patent announcem...
