Embodiment 1

[0052] The anionic surfactant purification composition in hair-washing wastewater comprises, in parts by weight, 18 parts of Hemerocallis extract, 12 parts of Catechin extract, 10 parts of Forsythia extract, 10 parts of Anemarrhena extract, and 100 parts of water.

[0053] The preparation method of the Hemerocallis extract is as follows: take 500g of Hemerocallis, wash and grind it into powder, add 3000mL of absolute ethanol, heat and reflux for 12h, filter, distill the filtrate under reduced pressure, concentrate the volume to 200mL, then add 500mL of distilled water, stir After uniformity, add 500mL n-butanol, separate the liquid, collect the n-butanol solution, distill under reduced pressure, concentrate the volume to 200mL, then add 2000mL anhydrous ether, a white precipitate appears, filter, and vacuum-dry for 5h to obtain a white solid. Dissolve the white solid in 700mL of absolute ethanol, add 50mL of 10wt% hydrochloric acid, heat to reflux for 5h, and concentrate to 200...

Abstract

The invention discloses a wool washing wastewater anionic surfactant purification composition which at least comprises a day lily extract, a catechu extract, a fructus forsythia extract, a rhizoma anemarrhenae extract and water.

Description

technical field [0001] The invention relates to the field of wool scouring wastewater, in particular to a composition for purifying anionic surfactants in wool scouring wastewater. Background technique [0002] With the continuous development of industrialization of human society, oil pollution caused by industrial discharge and leakage has received more and more attention. These oily wastewater mainly come from petrochemical, food, textile, leather, steel processing. A large amount of oily wastewater enters rivers and lakes, which will cause serious water pollution and environmental damage. The cleaning, recycling and reuse of oily wastewater has become a hot spot of common concern all over the world. However, there are many difficulties in the treatment of oily wastewater. For example, there are many types of oil and their viscosities are also different. It is often difficult to separate them from water bodies through simple physical or chemical actions. [0003] Wool w...
