摘　　要：采用酸析+UASB的组合工艺处理高浓度印染废水,工程运行结果表明:退浆水进水pH值10~13,COD_(Cr)≤25 000 mg/L,SS≤600 mg/L,碱减量水进水pH值10~13,COD_(Cr)≤25 000 mg/L,SS≤400 mg/L,处理后出水pH值6~9,COD_(Cr)≤2 500 mg/L,SS≤300 mg/L。该工程可有效降低高浓度废水的pH值调节费用,减少末端综合废水的处理成本和难度。The high concentration dyeing wastewater is treated by the combined process of acid precipi- tation and UASB. The operation results show that at the qualities of desizing wastewater inlets of pH value 10N13, CODcr≤25 000 mg/L, SS≤600 mg/L, and deweighting wastewater inlets of pH value 10-13, CODcr≤25 000 mg/L, SS≤400 mg/L, the water outlets feature pH value 6N9, CODcr≤2 ,500 mg/L, SS≤ 300 mg/L. The cost and difficulty of terminal wastewater treatment can be reduced efficiently by the project.
