Embodiment Construction

[0034] Below in conjunction with specific embodiment, content of the present invention is described in further detail:

[0035] The problem to be solved by the present invention is to provide a micro-nano ozone oxidation water treatment method and device that works stably, can improve ozone efficiency and water treatment effect, and solve the problem of poor mass transfer effect in traditional bubbling aeration.

[0036] In order to achieve the technical purpose, the technical solution of the present invention is a micro-nano ozone oxidation water treatment method, which is characterized in that it comprises the following steps:

[0037] S1: The sewage in the raw water pool 1 is lifted by the lifting pump 11 into the micro-nano bubble generator 2, and at the same time, the ozone gas generated by the ozonation generator 3 enters the micro-nano bubble generator 2 through the pipeline for mixed treatment;

[0038] S2: by mixing and producing a large amount of micro-nano bubbles a...

Abstract

The invention relates to a micro-nano ozone oxidation water treatment method and device. The micro-nano ozone oxidation water treatment device comprises a raw water tank, a micro-nano bubble generator, an ozonization tank, a water outlet tank and an ozonization generator, a micro-nano ozone oxidation water treatment system is constructed by combining ozone with the micro-nano bubble generator, sothat the mass transfer efficiency between the ozone and water is improved, the ozone efficiency and the water treatment effect are improved, the problem of poor mass transfer effect in traditional bubbling aeration is solved, and the micro-nano ozone oxidation water treatment system is high in practicability and good in working effect; by adopting the micro-nano bubble generator, the ozone gas generated by the ozonization generator is converted into micro-nano small bubbles, so that the specific surface area of the ozone bubbles is greatly increased, the gas-water contact area is increased, and meanwhile, the retention time of the micro bubbles in the water is prolonged, so that the mass transfer efficiency of a gas-liquid interface is enhanced.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a micro-nano ozone oxidation water treatment method and device. Background technique [0002] In sewage treatment, ozonation is usually used to treat refractory organic matter in water. Through the strong oxidation performance of ozone, the organic matter in the water can be completely mineralized to generate carbon dioxide and water, etc., and it can also be partially oxidized to convert the complex organic matter in the water into simple small molecule organic matter, improving the biochemical performance of sewage. The action of ozone with organic matter in water makes contact oxidation of organic matter based on dissolved ozone. Therefore, one of the keys of this technology is the dissolution effect of ozone in water, that is, the mass transfer efficiency of ozone. The mass transfer efficiency is affected by factors such as the contact area between phases and the con...
