Abstract

The invention relates to a treating method for removing three kinds of dioxin-like compounds in waste incineration waste off gas. The method comprises the steps that waste incineration waste off gas is introduced into a sufficient treating agent through a pipeline, 2,3,7,8-tetrachlorodibenzo-p-dioxin, 1,2,3,7,8-pentachlorodibenzo-p-dioxin, and 1,2,3,4,6,7,8-heptachlorodibenzo-p-dioxin in the off gas react with the treating agent, and complex precipitate is formed and filtered out. The treating agent is formed by compounding terpinyl acetate, n-butyllithium, 2-amino-3,5-dibromopyrazine, 2-amino butane, 4-(4-hydroxy-3-methoxyphenyl)butan-2-one, 4-acetoxyl group-3-methoxy-(2-propenyl) benzene, 2-methylpiperazine, 6-methyl chromene, 3alpha,12alpha-dihydroxy-5beta-cholanic acid and the like. The treating agent has the strong complexing power with target matter, the complex precipitate forming speed is high, the removing rate can reach 99%, the cost is low, consumption is small, the application range is wide, and no damage is produced to the environment.

Description

technical field [0001] The invention relates to a method for removing 2,3,7,8-tetrachlorodibenzo-p-dioxin, 1,2,3,7,8-pentachlorodibenzo-p-dioxin and 1,2 , The processing method of 3,4,6,7,8-heptachlorodibenzo-p-dioxin belongs to the technical field of environmental protection. Background technique [0002] Dioxin, also known as dioxin (qǐ), is an abbreviation for dioxins (Dioxins), which refers to substances that contain many congeners or isomers with similar structures and properties. Two types of organic compounds, dioxins mainly exist in the form of mixtures in the environment. Dioxins include 210 kinds of compounds. These substances are very stable, have a high melting point, are extremely difficult to dissolve in water, and can be dissolved in most organic solvents. They are colorless, odorless, fat-soluble substances, so they are very easy to accumulate in the body. Serious harm to human body. Among them, 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD) is by far ...
