Paper-making wastewater resource recycling and treating process method and paper-making wastewater resource recycling and treating system device

The invention belongs to the technical field of paper-making wastewater treatment, and in particular provides a paper-making wastewater resource recycling and treating process method and a paper-making wastewater resource recycling and treating system device. After the method and the device are used, a better paper-making wastewater treatment effect is achieved by means of ultrasonic pretreatment,the chemical oxygen demand (COD) removal rate can be increased by about 20%, and the total COD removal rate can reach 57-69%; after black liquid is treated by means of ultrasonic waves, the comprehensive toxicity is reduced, the sludge activity is enhanced, the active period shifts forward, and bone morphogenetic protein (BMP) of at the active period of methane bacteria is obviously improved. 本发明属于造纸厂废水处理技术领域，具体提供了造纸废水资源化回收处理工艺方法及处理系统设备。本发明中通过借助超声波预处理，对于造纸废水的处理取得了良好的效果，COD去除率可提高约20％，总COD去除率可达57％～69％；黑液经超声波处理后，综合毒性降低，污泥活性增强，活性期前移，甲烷菌活性期BMP显着提高。
