| Abstract: | Since CODcr and color of effluent water are difficult to satisfy the new emission standards,the secondary biochemical effluent water from a paper mill in Wuxi,Jiangsu Province was advanced treated by NaClO process.Effects of initial pH,NaClO dosage and reaction time and temperature on removal rate of CODcr and chrome were studied.Results indicated that under the conditions of pH 9,NaClO dosage 1.6 mL/L,reaction time 40min and temperature 35 ℃,removal rate of CODcr was 50%,and removal rate of color was 87.7%,which all can meet the new emission standard of DB32/1072-2007. |
