Drinking water aeration treatment device

Abstract

The invention discloses a drinking water aeration treatment device. The device comprises a gas storage tank, a sand settling tank and an aeration tank. Since the gas storage tank is connected with the aeration tank, the air in the aeration tank is introduced into water for long-timer contact; a water-forward plate, a grid plate and an aeration ball in the aeration tank are conductive to transferring oxygen in the air into water so as to obtain enough dissolved oxygen; oxidation treatment on organic matters in the water via the oxidability of oxygen is facilitated; the effects of removing carbon dioxide and hydrogen sulfide gas in water and removing iron and manganese are realized; oxidation of metal ions in water via the oxidability is promoted; and with the gas storage tank, the aeration treatment of water can still be guaranteed when gas pumping is stopped during intermittent water supply. The device disclosed by the invention saves energy and reduces consumption, realizes a good aeration treatment effect on the drinking water and reduces the water quality treatment cost and can be widely applied to the government organizations and institutions and residential areas.

Description

Technical field [0001] The invention relates to the technical field of water quality treatment, in particular to a drinking water aeration treatment device. Background technique [0002] Environmental pollution and substandard drinking water have caused eutrophication of water bodies. Especially after the water quality of tap water has been upgraded, the water quality of many water plants cannot meet the standards. This requires pretreatment of the raw water before drinking. The current pretreatment is more effective The method is the biological aeration filtration method. The granular filter material is filled in the device as a carrier. The microorganisms adhere to the surface of the carrier to form a biofilm. Aeration and oxygen supply are carried out under the filter material layer. The raw water and air flow in the same direction or reverse flow. , Relying on the adsorption, oxidation and decomposition of pollution by the biofilm attached to the surface of the carrier, water...

AI Technical Summary

Problems solved by technology

The water supply in residential areas is actually mostly intermittent water supply. The water consumption is reduced or stopped except for meals. At this time, the water pump is still aerating continuously, which wastes a lot of energy and increases the cost of water treatment. Therefore, from the perspective of benefiting the country and the people Considering, saving energy, reducing consumption, and reducing water supply costs are the top priorities at present
