Example Embodiment
[0020] Specific embodiment 1: This embodiment is a method of using singlet oxygen to remove algae. It is realized by the following steps: the catalyst and the oxidant are mixed in a molar ratio of 1: (1-10), and then added to the treatment. In the water, the concentration of peroxide in the algae-containing water to be treated is controlled to be 1 to 500 mg / L, and the treatment is performed under the condition that the residence time of the hydraulic reaction is 10 to 60 min and the condition is agitated to complete the algae removal with singlet oxygen; , The catalyst is pyruvic acid, and the oxidant is peroxide.
[0021] The principle of a method of removing algae using singlet oxygen in this embodiment is as follows: First, pyruvic acid catalyzes peroxide (peroxymonosulfate or percarbonate) to produce a diepoxy intermediate; The body further reacts with peroxide to produce singlet oxygen ( 1 O 2 ) And pyruvic acid, and at the same time the double epoxy intermediate will also ...
Example Embodiment
[0023] Specific embodiment two: this embodiment is different from specific embodiment one in that the peroxide is a mixture of one or more of peroxymonosulfate and percarbonate mixed in any ratio. Others are the same as the first embodiment.
Example Embodiment
[0024] Specific embodiment three: this embodiment is different from specific embodiment one in that the peroxide is peroxymonosulfate and sodium persulfate (NaHSO 5 ), potassium persulfate (KHSO 5 ), ammonium persulfate (NH 4 HSO 5 ), calcium persulfate (Ca(HSO 5 ) 2 ), magnesium persulfate (Mg(HSO 5 ) 2 ) Is a mixture of one or more of them in any ratio. Others are the same as the first embodiment.
