摘要
探讨了高吸附性的海泡石对造纸脱墨废水中COD_(Cr)的去除情况,为造纸废水的处理提供了新的思路和方法。实验结果表明,经高温或酸活化后的海泡石处理脱墨废水,可使废水中的COD_(Cr)去除率达80%以上。海泡石用于造纸脱墨废水处理具有很好的应用前景。
The feasibility of applying sepiolite to remove the CODcr of deinking wastewater, which provides a new way for the wastewater treatment of pulp and paper industry was studied. The results indicated that the removal rate of CODcr can reach up to 80% when the sepiolite modified by high temperature or acids is used. Therefore, application of sepiolite to remove the CODcr of pulp and paper mill＇s wastewater is feasible.
