利用粉煤灰输送系统预处理木浆造纸污水的研究

Study on Wood Pulp Papermaking Wastewater Pretreatment by Coal Ash Conveying System

针对造纸废水中含有木质素聚糖类、纤维素和碱浓度较高等特点,利用灰水混合体良好的吸附与沉降特性,通过热电厂粉煤处置系统对木浆造纸废水进行处理。结果表明,利用该工艺处理造纸废水可降低污染负荷65%以上,为降低造纸污水污染负荷提供了一个以废治废的有效途径。

According to the high concentration of lignin poly saccharide, cellulose and alkali in papermaking wastewater, the wastewater was treated by coal ash disposal system of the thermal power plant in consideration of ash water mixture＇s good adsorption and sedimentation characteristics. The results show that the pollution load can be reduced by over 65% by using the process to treat papermaking wastewater, which provides an effective way to reduce pollution load of papermaking wastewater.
