Description

Integrated sewage treatment equipment's multiple protection intelligent control aeration equipment

Technical Field

The utility model relates to a sewage treatment technical field specifically is a multiple protection intelligent control aeration equipment of integration sewage treatment device.

Background

Aeration is a means of bringing air into strong contact with water, and is aimed at dissolving oxygen in the air in water or expelling unnecessary gases and volatile substances in the water into the air. In other words, it is a means of facilitating mass exchange between gas and liquid. It also has other important functions such as mixing and stirring. The theory of mass transfer and diffusion is that the oxygen in the air is transferred into water through aeration, and the mass transfer and transfer of the oxygen from a gas phase to a liquid phase are carried out, and the theory of double membranes proposed by Liuyi and Whitman is more applied.

The double-membrane theory considers that an air membrane and a liquid membrane exist on a 'gas-water' interface, and air and liquid flow exists outside the air membrane and the liquid membrane, and belongs to a turbulent flow state; the air film and the liquid film are in a laminar state, convection does not exist, and air pressure gradient and concentration gradient can occur under certain conditions. If the oxygen concentration in the liquid film is lower than the saturation concentration of oxygen in water, oxygen in air continuously diffuses inwards to permeate the liquid film to enter the water body, so the liquid film and the air film become barriers to oxygen transfer, and the double-film theory is realized. Clearly, the most effective way to overcome the liquid film barrier is to rapidly switch the "gas-liquid" interface. The aeration stirring is just the same, and the specific method is as follows: the size of bubbles is reduced, the number of the bubbles is increased, the turbulence degree of liquid is improved, the installation depth of the aerator is increased, and the contact time of the bubbles and the liquid is prolonged. It is based on this that aeration apparatuses are widely used in sewage treatment.

Under the conditions of shutdown of a fan or sudden failure shutdown of the existing fan, a siphon phenomenon easily occurs in a pipeline, so that the water in a pool flows reversely, and the phenomenon of indoor overflow is caused; meanwhile, when the sewage contains components such as grease or protein, a large amount of foam is generated in the aeration process; along with the aeration, the decomposition of microorganisms in the aeration tank is increased continuously, so that the foam is generated more violently, and when the foam is accumulated to a certain height, the foam overflows out of the aeration tank to pollute a sewage treatment site and is difficult to clean; the foam also affects the speed of the wastewater as it passes through the filter membrane, resulting in poor treatment efficiency.
