A dosing and aeration system for water purification

Abstract

The invention discloses a dosing aeration system for water body purification. The dosing aeration system comprises a water storage tank to be treated, a uniform dosing and mixing tank, an aeration tank and a settling pond, wherein the water outlet end of the water storage tank to be treated is communicated with the water inlet end of the uniform dosing and mixing tank through a communicating tube;the water outlet end of the uniform dosing and mixing tank is communicated with the water inlet end of the aeration tank through a first water guide tube; a first water pump is arranged on the firstwater guide tube; the water outlet end of the aeration tank is communicated with the water inlet end of the settling pond through an effluent sucking tube; an effluent sucking pump is arranged on theeffluent sucking tube. Water in a stirring cavity and a liquid outlet annular cavity of the dosing aeration system is at a continuous rotational disturbance state, and thus a precipitant can be sufficiently mixed with sewage.

Description

technical field [0001] The invention belongs to the field of water purification, and in particular relates to an aeration system for water purification. Background technique [0002] Air aeration refers to the process of forcibly transferring 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 in the pool from sinking, strengthens the organic matter and microorganisms in the pool and the dissolved oxygen. The purpose of contact is to ensure that the microorganisms in the pool can oxidatively decompose organic matter in the sewage under the condition of sufficient dissolved oxygen, and the water and air are fully contacted to exchange gaseous substances and remove volatile substances in water. Escape from water, such as removing the odor of water or harmful gases such as carbon dioxide and hydrogen sulfide, or dissolving oxygen into water to increase the concentration o...

AI Technical Summary

Problems solved by technology

[0003] Sewage contains a large amount of organic matter, microorganisms, hydrogen sulfide, excessive iron, manganese and other low-priced bicarbonates, and there may be harmful bacteria in the water, which can be fully oxidized and sterilized by air combined with ozone aeration Treatment, the aeration efficiency of the existing aeration equipment is low, many bubbles have floated up to the water surface and burst before they have time to fully contact with the water, and the bubble dissolution rate is low
