Textile Dyeing Industry

1. Industry Overview

The dyeing and printing industry is a typical high-water-consumption, high-pollution sector. It generates enormous amounts of “three industrial wastes,” and its pollution characteristics are primarily reflected in the challenging treatment of wastewater.

Pollutant Category	Primary source	Major pollutants	Key features
Wastewater	Pre-processing	Desizing, scouring, and bleaching wastewater	High COD, strongly alkaline
	Dyeing/Printing	Dyes, additives	Difficult to decolorize; salinity inhibits biochemical treatment.
	Post-processing	Various hardly degradable organic additives	Poor biodegradability
Exhaust gas	Heat setting, drying	Cooking fumes, VOCs, and odors	The exhaust gas has a large volume and low concentration, making it difficult to collect and treat.
Solid Waste	Wastewater treatment, production process	Biochemical sludge, waste dyes/auxiliaries, waste packaging materials, waste fabrics	Biochemical sludge, waste dyes/auxiliaries, and waste packaging materials are classified as hazardous wastes and require professional disposal.

2. Solution

Governance in the dyeing and printing sector is one of the areas that Jullian Group has been deeply engaged in for a long time. We provide owners with the following efficient, stable, and mature technical solutions.

(1) Yingzhong Environmental Protection provides exhaust gas treatment and wastewater treatment equipment:

● Exhaust gases from setting machines: Industrial fume purification equipment;

● Dyeing and printing wastewater: physicochemical + biochemical wastewater treatment + reclaimed water reuse system;
