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

摘要：

牛仔服装漂染污水采用多种离子科学配制而成的XLD-C复合混凝剂混凝处理，CODcr去除率可达87%,脱色率90%以上，其效果优于硫酸铝、PFS和PAC,投资费用和日常运行费用降低，再经兼性生物膜氧化沟二级处理，出水可达到国家和厦门市一级排放标准。
