Abstract:

Jeans garment dye wastewater using variety made from ion science of XLD C composite coagulant coagulation treatment, CODcr removal rate can reach 87%, decolorization rate is above 90%, the effect is better than aluminum sulfate, PFS and PAC, investment costs and daily operation cost is reduced, then through facultative biofilm oxidation ditch secondary treatment, effluent can reach the xiamen city and national levels emission standards.

Key words: Compound coagulant, coagulation, Facultative biofilm oxidation ditch, Dye wastewater
