Background
The black and odorous river channel in cities is mainly caused by imbalance of oxygen supply and oxygen consumption of water bodies due to excessive sewage receiving, pollutants in the water bodies are converted under the anoxic and even oxygen conditions to generate odorous substances such as ammonia nitrogen, hydrogen sulfide, volatile organic acid and the like and black substances such as iron and manganese sulfide and the like. The black and odorous river not only can influence the harmony and beauty of the ecological environment, but also can aggravate the crisis of water resources, aggravate the shortage of water resources and worsen the ecological environment; but also harms the health of local residents; and the river pollution seriously causes the shortage of ground water, promotes the excessive exploitation of underground water to cause ecological problems, reduces the quality of the underground water, and greatly increases the hardness and the nitrate content. Therefore, the problems of black and odorous elimination, perception improvement and city beautification are mainly solved in river treatment.
Because the imbalance of oxygen supply and oxygen consumption of the water body is one of the main reasons for causing the water body to generate black and odorous, the aeration reoxygenation is considered as a measure for treating the pollution of the river channel, the existing aeration reoxygenation air outlet is usually a single channel, the oxygen enters the water through a single channel pipeline, and the oxygen is concentrated and cannot be fully dissolved in the water because the contact area of the oxygen with the water is limited, so that the good purification effect cannot be achieved, and the oxygen is wasted.

Example 1
Referring to fig. 1 and 2, a nano oxygen enrichment device for black and odorous water in urban inland rivers and lakes comprises: an oxygen generating chamber and a gas-liquid mixing chamber; a water inlet channel and a water outlet channel are respectively arranged at the two ends of the gas-liquid mixing chamber in the horizontal direction; an air inlet is formed in the upper part of the gas-liquid mixing chamber in the vertical direction; the oxygen generating chamber is provided with an oxygen bubble forming mechanism at the air outlet end, and the oxygen bubble forming mechanism is placed in the gas-liquid mixing chamber through the air inlet.
In this embodiment, the oxygen bubble forming mechanism is a conical structure; micropores are distributed on the wall of the oxygen bubble forming mechanism with the conical structure.

y=3x2+x；
wherein y is the aperture of the micropore, and x is the distance from the bottom surface of the cone on the bus. Because the water inlet channel and the water outlet channel of the gas-liquid mixing chamber are both arranged at the lower end of the gas-liquid mixing chamber, the water at the upper part of the gas-liquid mixing chamber flows slowly, and the water at the lower part of the gas-liquid mixing chamber flows quickly.

the black odorous water of the inland river lake flows into the gas-liquid mixing chamber from a water inlet channel of the gas-liquid mixing chamber, meanwhile, a gas valve at the gas outlet end of the oxygen generating chamber is opened, a gas pressure pump is started, oxygen generated by the oxygen generating chamber is output to the cylindrical oxygen bubble forming mechanism, and the oxygen is mixed with the black odorous water in the gas-liquid mixing chamber through micropores distributed on the peripheral wall and the bottom wall of the cylindrical oxygen bubble forming mechanism. The black and odorous water dissolved with oxygen flows out of the gas-liquid mixing chamber from the water outlet channel, so that the oxygen concentration in the black and odorous water in the inland lakes is improved, and the purpose of purifying the black and odorous water is achieved.
The oxygen bubble forming mechanism with the conical structure is arranged at the air outlet end of the oxygen generation chamber, the oxygen bubble forming mechanism with the conical structure is placed in the gas-liquid mixing chamber through the air inlet, micropores are distributed on the wall of the oxygen bubble forming mechanism with the conical structure, and oxygen output by the oxygen generation chamber is branched into multiple paths through the oxygen bubble forming mechanism. When the black odorous water of the inland rivers and lakes flows into the gas-liquid mixing chamber, the black odorous water of the inland rivers and lakes contacts the oxygen bubble forming mechanism, oxygen on the surface of the oxygen bubble forming mechanism is taken away by the flowing black odorous water of the rivers and lakes, and the oxygen is dispersed and dissolved in the black odorous water of the inland rivers and lakes, so that the oxygen concentration in the black odorous water of the inland rivers and lakes is improved, and the aim of purifying the black odorous water of the rivers and lakes.
