Description

A fully automated rapid oxygenation ecosystem for water treatment

technical field

Basic theory and applied basic research technology fields of engineering, hydraulics and mechanical engineering disciplines. the

Background technique

With the development of the economy and the intensification of urbanization, the amount of industrial and domestic water and the amount of sewage and wastewater produced is increasing day by day, and the increasing amount of sewage and wastewater discharge has increasingly become a negative factor restricting sustainable development. Regardless of whether a large amount of urban sewage and wastewater has been treated or not, regardless of the depth of treatment, most of them will eventually be discharged into the environmental water body. the

The amount of dissolved oxygen in water is not only an important indicator to measure the self-purification ability and water quality of the water body, but also an important indicator to evaluate the growth of fish. Molecular oxygen dissolved in water is called dissolved oxygen, expressed in milligrams of oxygen per liter of water. When the water body is polluted by organic matter and inorganic reducing substances, the amount of dissolved oxygen in the water will drop, even close to zero. At this time, the organic matter will decompose and ferment under anoxic conditions, making the water body black and smelly, leading to deterioration of water quality . When the dissolved oxygen value in the water drops to 3-4mg/L, some fish have difficulty breathing; high dissolved oxygen is beneficial to increase the oxidation-reduction potential and make the organic matter decompose faster, which is beneficial to NH ₄ >NO ₂ >The reaction process of NO ₃ makes the water quality clear and the fish are not prone to problems.

Generally, the process of dissolved oxygen in water can only occur at the interface between the surface of the water and the air, and the high and low oxygen-containing water can reach a relatively balanced dissolved oxygen through diffusion and convection. The dissolved oxygen in the water will be constantly replenished due to the incorporation of oxygen in the air and the photosynthesis of green aquatic plants. In traditional sewage and wastewater treatment, the oxygen content of water is generally increased by the principle of diffusion. This method is inefficient and the process is uncontrollable; the mechanical oxygenation device commonly used in the aquaculture industry also has limited oxygenation, Shortcomings such as insufficient energy efficiency ratio. the
