Sterilizing and precipitating system for water treatment and method thereof

Abstract

The invention discloses a sterilizing and precipitating system for water treatment. The sterilizing and precipitating system for water treatment comprises a aeration tower and a precipitation tower, wherein the water outlet end of the aeration tower is communicated with the water inlet end of the precipitation tower through a water outlet and suction pipe; a water suction pump is arranged on the water outlet and suction pipe; the water suction pump can suck aerated water in the aeration tower into the precipitation tower. The sterilizing and precipitating system for water treatment adopts a precipitate passage structure, so that discharge of excessive clean water along with a precipitate is effectively avoided; meanwhile, under the rotational agitation of auger blades in an aeration device, an air bubble group violently rolls in a column passage, so that the contact area between bubbles and a water flow is increased, the fluidity is improved, and thus the dissolution efficiency is improved.

Description

technical field [0001] The invention belongs to the field of water treatment, in particular to a bactericidal precipitation system and method for water treatment. Background technique [0002] Air aeration refers to the process of forcibly transferring the oxygen in the air to the liquid, the purpose of which is to obtain sufficient dissolved oxygen in the water; in addition, aeration also prevents the suspension of the pond from sinking, and strengthens the organic matter, microorganisms and dissolved oxygen in the pond. The purpose of contact, so as to ensure that the microorganisms in the pool can oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen, the water treatment method that the water and the air are fully contacted to exchange gaseous substances and remove volatile substances in the water, or make the gas from Escape from water, such as removing the odor of water or harmful gases such as carbon dioxide and hydro...

AI Technical Summary

Problems solved by technology

[0003] Sewage contains a large amount of organic matter, excessive iron, manganese and other low-priced bicarbonate and other substances, and there may be harmful bacteria in the water, which can be treated with air combined with ozone aeration before precipitation. Existing aeration equipment The aeration efficiency is low, many bubbles have floated to the water surface before they have time to fully contact with the water, and the utilization rate is low
