摘　　要：根据粘胶纤维生产特点,对某厂浆粕黑液废水采用酸析+CASS+气浮工艺技术进行处理。中试研究表明:处理后出水COD<100mg/L、BOD<20mg/L、SS<70mg/L、色度<70倍、Zn<2.0mg/L,除色度外,各项指标可以满足GB89781996一级排放标准要求。并且根据中试装置的运行进行了经济技术分析,为工程设计提供理论依据。The plasm-scum black liquor of some factory was cleaned by a process named acid-out +CASS+ air-floatation in an industrialization test, according to the characteristic of viscose fibre production .The industrialization test showed that index of discharged water through the process as such: COD<100 mg/L、BOD<20 mg/L、SS<70 mg/L、chroma<70 times、Zn<2.0 mg/L.Every index can satisfy the grade 1 of the waste water discharge criterion in the GB8978-1996, only except for chroma. An economic and technical analysis has been done according the test. All these work can provide a theoretical basis for engineering design.
