Sales Hotline:


As an indispensable process in clothing industry, textile dying industry is both loved and hatred by people. What people love is that through the development of the printing and dyeing industry, life becomes more beautiful and clothes more colorful. What people hate is that printing and dyeing industry is a well-known major pollution source. The printing and dyeing wastewater has the characteristics of large changes in water quality, high concentration of organic pollutants, large changes in chroma and PH value and etc. Printing and dyeing sludge contains dyes, slurries and additives. Composition of printing and dying sludge is very complex. Structure of dye contains nitro, amino compounds and heavy metal elements such as copper, chromium, zinc and arsenic. Dye holds relatively large biological toxicity and strong pollution to the environment. Dye is regarded as hazardous waste. Currently, printing and dyeing sludge is uniformly collected by qualified sludge recycling agency for recycling which will cost certain expense. Therefore, for many printing and dyeing enterprises, it is also a large cost. With continuous growth of urban population and rapid development of industrial production, volume of urban domestic sewage and industrial waste water keep increasing day by day. Printing and dyeing waste water occupies a large proportion in our country's industrial waste water and mainly exists in coastal regions including Guangdong, Zhejiang, Jiangsu, Fujian and Shandong. Composition of printing and dyeing waste water is complex and it mainly contains a large amount of dyes, slurry material, surfactants and alkalis. At the same time, owing to large chroma, strong alkalinity and high organic content, printing and dyeing sludge is one of industrial waste water relatively difficult to treat.
Printing and dyeing sludge is residue produced during waste water treatment process of printing and dyeing enterprises. It contains a certain amount of pollutants mainly including bacterial microorganisms, organic debris, inorganic substances and colloids. It is an extremely complex heterogeneous body with high organic content and high heat. With vigorous development of printing and dyeing industry, disposal regulations in our country becomes stricter and stricter. After waste water treatment plant matched for printing and dyeing enterprise put into operation, a large amount of sludge is produced every day correspondingly.  What’s more, after disposal of printing and dyeing waste water tends to be centralized, amount of sludge increases day by day and composition of sludge produced is becoming more and more complex. Common treatment method for sludge produced in large amount is to use a mechanical filter press to reduce moisture content of sludge below 80%. Then, transport the sludge out and do final disposal by landfill, stacking, or dumping way. Such disposal methods often cause secondary pollution to natural environment and bring about severe environmental safety hazards.
Mature treatment method of printing and dyeing sludge is to reduce its volume by drying and do resource disposal. Common resource utilization method is ①use dried sludge as fuel for incineration to replace coal consumption and reduce enterprises’ production cost; ②mixing into shale material and make sintered bricks; ③Use sludge to produce high-temperature calcined ceramsite. Based on above resource utilization methods, TAEDA can design drying plan and can also provide complete deep processing technology and equipment manufacturing support services.
