| 摘 要： | 采用常规混凝剂对木浆(A厂)和竹浆(B厂)生化处理前后的中段废水进行了混凝脱色处理。研究表明,PAC和PAM可以降低制浆中段废水的色度和CODCr;B厂竹浆中段废水的混凝脱色处理效果优于A厂木浆中段废水,但B厂CODCr去除效果不如A厂好;生化处理后A厂中段废水的混凝脱色率优于生化处理前,B厂中段废水经生化处理和混凝后,色度由431 C.U.降至220 C.U.。

| Abstract: | The coagulation treatment of the effluent from bleaching and washing plants where wood or bamboo are used as raw material are studied.The results show that the chroma and COD_(Cr) are reduced after treatment by using conventional coagulants of PAC and PAM.The decoloring of coagulation treatment on the effluent of bamboo pulping is better than on the effluent of wood pulping,the discoloring efficiency is better than COD_(Cr) removal efficiency in the bamboo pulp mill,the discoloring effect in the wood pulp mill is more notable after the effluent is treated by biochemical process. |
