発明の名称
(EN) METHOD AND DEVICE FOR TREATING WASTEWATER CONTAINING ORGANIC MATTER
(ZH) 含有机物的废水的处理方法及装置
要約
(EN)
Provided are a method and a device for treating wastewater containing organic matter, with which it is possible to use ozone to efficiently remove, by breaking down, organic matter in wastewater containing the organic matter and inorganic carbonates. Water to be treated is subjected to a decarbonation treatment using an inorganic carbonate removal device 3, hydrogen peroxide is added, an ozone-containing gas is added by an ejector 8, the water to be treated is channeled to a static mixer 13, and the organic matter is subjected to an oxidation treatment. The ratio A/B between the ozone concentration A(g/Nm<3>) of the ozone-containing gas and the inorganic carbonate concentration B (g/L) of the water flowing into the ejector is set to 500-1000.

(ZH)
提供一种含有机物的废水的处理方法及装置,其能够利用臭氧高效地分解并去除含有机物及无机碳酸的废水中的有机物。通过无机碳酸去除装置(3)对待处理水进行脱碳酸处理之后,添加过氧化氢,用喷射器(8)添加含臭氧的气体,并将水通入静态搅拌器(13),进行有机物的氧化处理。含臭氧的气体中的臭氧浓度A(g/Nm3)与流入该喷射器的水中的无机碳酸浓度B(g/L)之比A/B为500~1000。
