A Nano Oxygen Enrichment Device for Black and Odor Water Body in Inland Rivers and Lakes

Abstract

The invention relates to a nanometer oxygen enrichment device for black odorous water bodies in urban inland rivers and lakes. The nanometer oxygen enrichment device includes an oxygen generating chamber and a gas-liquid mixing chamber. The two ends of the gas-liquid mixing chamber in the horizontal direction are provided with a water inlet channel and a water outlet channel respectively, the upper portion of the gas-liquid mixing chamber in the vertical direction is provided with an air inlet, and the air outlet end of the oxygen generating chamber is provided with an oxygen bubble forming mechanism which is placed in the gas-liquid mixing chamber through the air inlet. The air outlet end of the oxygen generating chamber is provided with the oxygen bubble forming mechanism which is placedin the gas-liquid mixing chamber through the air inlet, and oxygen output by the oxygen generating chamber is divided into multiple branches through the oxygen bubble forming mechanism. When black odorous water in urban inland rivers and lakes flows into the gas-liquid mixing chamber and comes into contact with the oxygen bubble forming mechanism, the flowing black odorous water in the rivers andthe lakes takes away oxygen on the surface of the oxygen bubble forming mechanism, the oxygen is dispersed and dissolved in the black odorous water, so that the concentration of oxygen in the black odorous water in the inland rivers and lakes increases, thereby eventually reaching the goal of purifying black odorous water in the urban inland rivers and lakes.

Description

technical field [0001] The invention relates to the technical field of environmental treatment equipment, in particular to a nanometer oxygen-enriching device for black and odorous water bodies of inland rivers and lakes in cities. Background technique [0002] The black and smelly rivers in cities are mainly caused by the imbalance of oxygen supply and consumption in the water body due to excessive pollution. Under the condition of hypoxia and even oxygen in the water body, the pollutants transform and produce ammonia nitrogen, hydrogen sulfide, volatile organic acids and other odorous substances, as well as iron, Black substances such as manganese sulfide. The black and smelly river will not only affect the harmony and beauty of the ecological environment, aggravate the crisis of water resources, aggravate the shortage of water resources, and deteriorate the ecological environment; it will also endanger the health of local residents; it will also cause insufficient surface...

Problems solved by technology

[0004] In order to overcome the problems in the prior art that oxygen enters the water through a single-channel pipeline, the contact area with the water is limited, and the oxygen cannot be fully dissolved in the water, the present invention provides a nano-oxygen enrichment device for black and odorous water in urban inland rivers and lakes.
