Aeration stripping system and method for dealing with sudden odor-causing substance pollution in drinking water

Abstract

The invention discloses an aeration air stripping system and method responding to sudden odorous substance pollution of drinking water. The system comprises an aeration column used for simulating the water body, wherein a bottom support is arranged at the bottom of the aeration column, a water outlet and multiple sampling openings are sequentially arranged on the side wall of the aeration column from bottom to top, an aeration head is arranged in the aeration column, the aeration head is arranged on the bottom support, and the aeration head can be connected with an air pump arranged at the outside of the water body through an aeration air stripping hose. In the invention, the odorous substance is transferred from the water phase to the gas phase for removal through aeration, and the system can be used for removing such excessive odorous substances in the drinking water as geosmin, 2-methylisoborneol and the like; the necessary air-water ratio is determined by the times of ultra standard of the odorous substance in water; the aeration air stripping system and method disclosed by the invention has the advantages of having simple operation and low operation cost, generating no influence on the normal operation of water plants, facilitating application in the water plants and responding to the sudden odorous substance pollution of drinking water efficiently, safely and economically.

Description

technical field [0001] The invention belongs to the field of water treatment, and in particular relates to an aeration and stripping system and method for dealing with sudden pollution of drinking water by smell-causing substances. Background technique [0002] Smell is an important sensory property index in drinking water quality standards, although there is no specified limit value for this index in surface water quality standards; The limitations of water technology lead to the risk of abnormal smell and taste in drinking water, and urban water supply companies have to face the problem of dealing with excessive smell-causing substances. At present, there are mainly two methods that can be used to treat the smell and taste of drinking water: powdered activated carbon adsorption method and chemical oxidant oxidation method, but both of them have problems of high cost or low efficiency to varying degrees. [0003] The powdered activated carbon adsorption method utilizes the...
