Problems solved by technology

In addition, the purpose of the present invention is to provide a method for promoting oxidation treatment, which does not have the problem that the ozone cannot be controlled without dissolved ozone, uses widely used measuring instruments, and uses simple operations to control the injection amount of ozone and hydrogen peroxide. Too much will not be enough, save waste

Embodiment Construction

[0032] Hereinafter, the present invention will be described in detail.

[0033] As the raw water to which the accelerated oxidation treatment method is applied in the present invention, any water can be used as long as it is water that can be purified. Specifically, river water, lake water, sewage, etc. are preferably used as Raw water. The raw water can be used directly or pre-treated. For example, the raw water may be placed beforehand to remove sediments, or a coagulant may be added and agitated to remove polluting substances from the raw water to a certain extent.

[0034] In the present invention, in the ozone contact step, the above-mentioned raw water is subjected to ozone treatment, but a general ozone generator can be used as an ozone generating device, and there is no particular limitation.

[0035] Ozone generated by the ozone generator is injected into the ozone contact tank. Such ozone contact may be performed in a commonly used ozone contact tank. In the ozon...

Abstract

An oxidization promoting method used in treating water features that after the ozone gas is contacted with the water to be treated, the ozone gas and hydrogen peroxide are filled while their filled amounts are controlled for preventing overfill or underfill.

Description

technical field [0001] The present invention relates to an accelerated oxidation treatment method for oxidative decomposition of refractory substances in water which cannot be decomposed by ozone alone, using ozone and hydrogen peroxide together. More specifically, it relates to an accelerated oxidation treatment method for efficiently and safely performing accelerated oxidation treatment of refractory substances in water by controlling the injection amount of ozone and hydrogen peroxide in the accelerated oxidation treatment step. Background technique [0002] Water treatment such as sterilization, decolorization, deodorization, and oxidative removal of organic and inorganic substances is widely used by dispersing ozone gas in water by utilizing the strong oxidizing power of ozone, which is second only to fluorine. In particular, in the waterways in the suburbs of the city, the harm of the odor caused by the water intake source is wide. Due to the strong oxidizing power of ...
