Ozone-ultra-micron air bubble-filtering system and ozone-ultra-micron air bubble-filtering method

Abstract

The invention discloses an ozone-ultra-micron air bubble-filtering system and an ozone-ultra-micron air bubble-filtering method. Domestic sewage is treated by utilizing an ozone-ultra-micron air bubble-filtering process, and is treated according to a water quality condition of the domestic sewage through changing an adding quantity of ozone and hydraulic retention time; according to water quality properties of the domestic sewage, a certain quantity of the ozone needs to be added before ultra-micron air bubbles to remove part of organic matters, improve dissolved oxygen and remove odor when the sewage is treated under the conditions that the sewage contains a lot of organic matters, the dissolved oxygen is low, a water body is odorous and the like; if the sewage contains a few of the organic matters and the water body is not odorous, predicated emission standards can be reached through an ultra-micron air bubble and filtering process. By combining the ozone oxidized organic matters, the ultra-micron air bubbles and a filtering process are combined to treat the domestic sewage, so that the treatment of the domestic sewage has pertinence and the removing effect of suspension matters and the organic matters is obvious.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an ozone-ultramicro bubble-filtration system and a method thereof. Background technique [0002] Due to the increasingly serious pollution of water resources in my country and the shortage of urban water resources, most of the treatment methods for domestic sewage are activated sludge methods. The problem with activated sludge methods is that there are air bubbles in the ordinary aeration process. Large particle size, low oxygen transfer rate, short hydraulic retention time, etc., while the traditional process is cumbersome, and the structure occupies a large area. Contents of the invention [0003] The purpose of the present invention is to provide an ozone-ultramicron bubble-filtration system and its method, aiming to solve the problem of large bubble particle size, low oxygen transfer rate, short hydraulic retention time, cumbersome process, and large are...
