γ-丁内酯与N-甲基吡咯烷酮联产装置废水处理研究

Study on the wastewater treatment in the cogeneration device with the N-methyl pyrrolidone and gamma-butyrolacton

γ-丁内酯与N-甲基吡咯烷酮联产装置废水处理采用改良性两级A/O工艺,在现有设施的基础上实行废水达标排放、出水水质优良、稳定,工艺简单,装置占地面积少。

The modified two-stage A/O process was used in waste water treatment of gamma-butyrolacton and N-methyl pyrrolidone cogeneration plant,on the basis of existing facilities,company wastewater discharge reached standards,water quality was excellent and stable,process was simple,land area required for device was less.
