| 摘 要： | 羧甲基纤维素(CMC)生产废水在ρ(COD)=35 000 mg/L,ρ(Cl-)>27 000 mg/L的情况下,系统采用联动调试,通过接种活性污泥并依梯度启动各单元调试,在逐渐提高进水浓度的情况下,以TDS作为控制指标,经过120 d的驯化培养,驯化出耐高盐型活性污泥。当ρ(Cl-)上升到27 000 mg/L时,生化系统中COD依然保持较高的处理效率,MBR系统出水稳定达标。

| Abstract: | The wastewater from producing carboxymethyl cellulose contains COD and Cl-being up to 35000 mg/L and 27000 mg/L respectively,so linkage debugging is used for the system.Through inoculating activated sludge,operating each debugging unit in turn,increasing the concentration of the influent gradually and regarding TDS as the control target,the activated sludge resistant to high salt is acclimated after 120 d.When the concentration of Cl-is up to 27000 mg/L,a higher removal rate of COD still remains in the system,and the efflucent of MBR system meets the emission standards steadly. |
