Abstract

The invention relates to a treatment agent used for removing polychlorinated dibenzofuran in waste incineration tail gas. The treatment agent is prepared from taraxasterol acetate, potassium ethoxide,4-aminoisoquinoline, oleanolic aldehyde, phytolaccoside, 4-acetoxy-3-methoxy-(2-propenyl) benzene, 1,4-Dimethyl-piperazine, hydroxypropyl bi(trimethyl ammonium diiodide), 3-oxo-olean-12-en-28-oic acid. Combination capacity of the treatment agent with target substances is high, complex precipitate formation speed is high, removing rate is as high as 99%, cost is low, using amount is small, application range is wide, and no environment influence is caused.

Description

technical field [0001] The invention relates to a method for removing 2,4,7,8-tetrachlorodibenzofuran, 1,2,3,7,8-pentachlorodibenzo-p-furan and 2,3,4,7 The invention relates to a treatment agent for 8-pentachlorodibenzo-p-furan, which belongs to the technical field of environmental protection. Background technique [0002] Dioxin, also known as dioxin (qǐ), is an abbreviation of Dioxins, which refers to two dioxins that contain many congeners or isomers that are very similar in structure and properties. Like 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) ...
