混凝-SBR法联合处理造纸废水
Treatment of Papermaking Wastewater by Coagulation-SBR Combined Processes
摘要
Abstract
The treatment of the papermaking wastewater by using coagulation,SBR,and coagulation-SBR combined processes were studied.The effects of coagulant type,the dosage of coagulant,pH and stirring rate on treatment efficiency were discussed.The results indicated that the PFS（poly ferric sulfate） was more efficient than FeSO and AlSO for the treatment of papermaking wastewater.Orthogonal test showed that the dosage of PFS had significant influences in the removal of chemical oxygen demand（COD）.The removal rates of COD were low and not ideal with direct coagulation process and direct SBR process.With using coagulation-SBR combined processes,the COD of papermaking wastewater was reduced from 15€E？84 mg/L to 741 mg/L and the total removal rates of COD was observed to be 95.4%.The COD of papermaking wastewater can be attained to national control standard with solar photo-Fenton oxidation after coagulation-SBR combined processes.关键词
