Among the above process, the water processor is patented technology, slag filter, efficiency fine filtration, activity agglomerate absorption are new-developed technologies of our company.  

(2) Physico-chemical treatment

3According to the deep understanding of dyeing wastewater treatment projects home and abroad for years, combining with new technology development and research on printing and dyeing wastewater treatment, our company put forward the following two treatment methods:

Current treatment methods
(1) Under normal circumstances, COD value of printing and dyeing wastewater is at 300-1200mg / L, B
( that has been functioning home and abroad, its biological and chemical treatment methods are mainly activated sludge, biofilm method and anaerobic law etc.

1,COD300-1200mg/L ,BOD150-800mg/L.,

There are only two kinds of raw materials for textile industry, natural fiber and chemical fiber. Natural fibers includes: cotton, wool, hemp and silk. Chemical fibers includes synthetic fibers (polyester, acrylic, nylon, PVA, polypropylene, etc.) and man-made fibers (viscose, etc.) But when printing and dyeing, different dyes and auxiliaries are used, so toxic and harmful ingredients in the wastewater varies, which make printing and dyeing wastewater treatment complex.
