混凝-ClO_2氧化-吸附法处理脱墨废水

Treatment of Deinking Wastewater by Coagulation-ClO_2 Oxidation-Adsorption

采用混凝-ClO2氧化-吸附法处理脱墨废水,实验结果表明,对于CODCr为750mg/L,SS为1100mg/L,色度为55倍的脱墨废水,经此工艺处理后,CODCr降低到89.2mg/L,色度为8倍,出水完全达到并超过GB3544-2001所规定的排放要求并且能循环回用。

Treatment of deinking wastewater with coagulation, ClO2 oxidation and adsorption method is investigated. The result showed that the CODcr can be reduced from 750 mg/L to 89.2 mg/L and the color unit can be reduced from 55 to 8 after treatment with the coagulation ClO2 oxidation and adsorption method. The treated deinking wastewater can meet the requirement of national standard of GB3544-2001 and be recycled.
