The results showed that the rheological property of concentrated effluent from bamboo chemical mechanical pulping process was better than that of black liquor from bamboo chemical pulping process at the same concentration. The chlorine content of concentrated effluent （0.94%） was closed to that of bamboo chemical pulping black liquor. Both calorific value （high calorific value was 11.91 MJ/kg， low calorific value was 10.89 MJ/kg） and expansion volume （19.52 mL/g） were slightly lower than bamboo chemical pulping black liquor. There was a linear relationship between the solid concentration （Y） and Baume degree （X） in the concentrated effluent with the relationship equation of Y=1.5196X-1.693， indicating that alkali recovery technology could be used for its treatment. After the mixed wastewater was treated by anaerobic-aerobic+Fenton deep oxidation， the removal rate of COD_Cr was 97.3%. The qualities of the treated effluent could meet the demand of Discharge Standard of Pulp and Paper Industry Water Pollutants （GB 3544—2008）.]]> 2021/7/27 0:00:00 ZHANG Yu,SU Zhenhua,FAN Shujie,GONG Chen,NI Jianping,YANG Bin 2true 2021/7/27 0:00:00 HE Guanzhou 1true
