Abstract

The invention belongs to the technical field of waste water treatment, and proposes a wastewater treatment process for alkaline magenta production, comprising the following steps: S1, adding an acid-base regulator to the alkaline magenta wastewater to be treated to adjust the pH of the waste water to 5.5- 6; S2, after dissolving chlorin with ethanol, add it to the poloxamer aqueous solution, add chitosan, stir to obtain the wastewater treatment agent, and set aside; S3, add the wastewater treatment agent to the pH-adjusted wastewater, Stirring for 20-60 minutes; S4, irradiating the stirred wastewater under an ultraviolet lamp for 10-60 minutes; S5, centrifugally filtering the irradiated wastewater, testing the filtrate, and discharging it after passing the test. The invention solves the problem of low treatment efficiency of alkaline magenta wastewater in the prior art.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment, and relates to a waste water treatment process for alkaline magenta production. Background technique [0002] Basic magenta green, also known as basic green 4, is a kind of dye and pigment, and its molecular formula is C 23 h 25 N 2 , the molecular weight is 329.46, green with flashing crystals, soluble in water, very soluble in ethanol, all in blue-green color, adding sodium hydroxide to its aqueous solution to produce white precipitate with green light, dyeing at high temperature (120°C), The color light remains unchanged, and the light fastness of dyeing on acrylic fiber is 4-5 grades. [0003] With the development of industrial economy, alkaline magenta is widely used in industrial fields such as textile, leather, paper, rubber, plastic and food. In the production process of alkaline magenta, a large amount of dye wastewater is produced, with high chroma and COD. The emissio...
