摘要
本文研究了混凝-吸附法对全棉杆化学预处理机械法制浆造纸综合废水的处理效果,探讨了混凝处理中PAC投加量、PAM投加量、pH值,吸附处理中吸附时间、煤渣投加量对废水处理效果的影响。在PAC投加量为120mg/L、PAM投加量为8mg/L、pH值为6.3、煤渣投加量为160g/L、吸附时间为30min的条件下,废水的色度、SS和CODCr去除率分别达到96.6%、98.3%和86.8%,煤渣吸附过程符合Freundlich模型。
The treatment of whole cotton stalk P RC-APMP effluent by coagulation-adsorption combined process was studied, and the influence of PAC dosage, PAM dosage, pH value in coagulation process, and cinder dosage, cinder absorption time in adsorption process on the treatment were discussed. The results showed that when PAC dosage 120mg/L, PAM dosage 8mg/L, pH value 6.3, cinder dosage 160g/L, absorption time 60 min, the removal rates of color unit, SS, and CODcr of the pulping and paper making effluent could reach up to 96.6% , 98.3% and 86.8% respectively. Cinder absorption process could fit with the Freundlich model.
