摘要
根据牛仔服洗涤废水特性，提出了混凝一生物氧化法组合工艺流程，工程实践表明：废水COD由696～3401mg／L降至38～135mg／L，LAS由2．05～14．1mg／L降至未检出～3．12nag／L，色度由100～1600倍降至5～48倍，出水可达到《污水综合排放标准》（GB8978—1996）一级标准。该处理工艺具有结构紧凑简洁、运行控制灵活、抗冲击负荷、污泥量小等特点，为牛仔服洗涤企业废水处理探索了一条可行的途径。
According to the characteristics of wastewater of washing jeans, we adopted the techrdogy of coagulation-biological oxidation.The project practice indicates that the diluent of COD reduees to 38-135 mg/L from 696～3401 nag/L, LAS reduces to no detection till 3.12 mg/L from 2.05～ 14.1 mg/L, color reduces to 5～48 times finn 100～ 1600 times, so the diluent can comply with the Class A of Integrated Wastewater Discharge Standard （GB8978-1996） . This technology of wastewater treatment has many advantages, such as conapact structure, good properties of operatinal control and anti-shock loading, and less sludge quantity. Such characteristics explore a feasible way for wastewater treatment of jeans-washing enterprises.
