Abstract

The invention relates to an adsorption composition for treating textile wastewater. The adsorption composition comprises the following components in parts by weight: 30-40 parts of active bentonite, 60-70 parts of active attapulgite clay, 1-5 parts of polyferric sulfate, 1-4 parts of polyacrylamide, 30-50 parts of calcium oxide, 12-18 parts of aluminium potassium sulfate, 2-4 parts of diatomite, and 20-26 parts of active carbon. Through the adsorption composition of the invention, the textile wastewater can be effectively treated, and the composition has excellent treatment effect on the increasingly serious textile wastewater. The textile wastewater is treated through the adsorption composition, the treatment effect is obviously superior to that in the prior art, and is obviously superior to the state specified emission standard.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an adsorption composition for textile wastewater treatment. Background technique [0002] There are a large number of textile printing and dyeing enterprises in my country. Printing and dyeing wastewater is discharged from printing and dyeing factories that mainly process cotton, hemp, chemical fibers and their blended products. Textile printing and dyeing industrial wastewater has deep color, high alkalinity, and high content of organic pollutants. The water quality changes greatly and the composition is complex; the waste water contains dirt, grease, salt on the textile fibers, and various pulps, dyes, surfactants, additives, acids and bases and other pollutants added in the process of processing. The content of COD and BOD is high; the chromaticity and other indicators of wastewater usually far exceed the discharge standard, the discharge volume is large, the concentration is h...
