Fujian million strong environmental protection engineering Co. Ltd.   

        product introduction of printing and dyeing wastewater is the processing of cotton, linen, chemical fiber and blended products of the printing and dyeing factory discharged wastewater. Printing and dyeing wastewater [1] water amount is larger, each processing 1 tons of textile printing and dyeing water consumption of 100 ~ 200 tons, of which 80 ~ 90% become wastewater. Water product attributes such wastewater of large, high chroma, complicated component, in general can be taken hydrolytic acidification contact oxidation treatment of printing and dyeing wastewater by physicochemical method. Use and maintenance of process flow is as follows: the water quality of printing and dyeing wastewater, regulation pool, the coagulation reaction pool 1, primary sedimentation pool, pool acid hydrolysis, contact oxidation pond, oxidation reaction tank, the coagulation reaction pool 2, two sedimentation tank, intermediate pool, filter, clean water tank to discharge other descriptions of the complex printing and dyeing wastewater according to the source, the pollutant can be divided into two categories: one category from the fiber raw material itself entrainment; another kind is used in machining process, the slurry oil agent, dyestuff, chemical additives.
