  • 摘要: 以某制浆造纸厂生化出水Fenton/絮凝深度处理工艺长期运行数据为依据,系统分析了H2O2、废酸液(FeSO4含量约8%)、硫酸铝、PAM及氧化钙等处理药剂用量与水量、进水负荷和COD去除量之间的关系。结果表明, H2O2、废酸液、硫酸铝、PAM及氧化钙的单位水量平均投加量分别为0.05、2.18、0.07、0.0075和0.27 kg/m3,而去除单位COD的药剂平均消耗量分别为0.20、8.48、0.27、0.029和1.06 kg/(kg COD);H2O2、废酸液、硫酸铝和氧化钙的用量随进水负荷的增大而增加,而PAM随进水负荷的变化较小。H2O2和FeSO4的投加摩尔比(MH2O2/Fe2+)主要集中在1.0~2.0之间,其中在1.0~1.6之间的累积频率达到93%。该工艺的出水COD和SS分别为65~100 mg/L和20~30 mg/L,达到《制浆造纸工业水污染物排放标准》(GB 3544-2008)排放要求。废水深度处理成本约为1.01元/m3,其中药剂费用约0.58元/m3,占56.98%。
    Abstract: The relation of H2O2, waste acid (8% FeSO4), Al2(SO4)3, PAM, CaO and treatment capacity, influent load, COD removal were analyzed based on the long term operation date of a Fenton/flocculation process used for advanced treatment of pulp and papermaking wastewater. The average dosages of H2O2, waste acid, Al2(SO4)3, PAM and CaO to unit volume of wastewater were 0.05 kg/m3,2.18 kg/m3,0.07 kg/m3,0.0075 kg/m3 and 0.27 kg/m3, respectively,and the average reagent consumption of COD removed were 0.20 kg/(kgCOD),8.48 kg/(kgCOD),0.27 kg/(kgCOD),0.029 kg/(kgCOD) and 1.06 kg/(kgCOD), respectively. The dosages of H2O2, waste acid, Al2(SO4)3 and CaO increased with the increase of influent load, but PAM had no significant change. The molar ratio of H2O2/Fe2+ (MH2O2/Fe2+) was about 1.0~2.0, and the cumulative frequency of MH2O2/Fe2+ between 1.0 and 1.6 was about 93%. The effluent COD and SS were 65~100 mg/L and 20~30 mg/L, respectively, and met the Discharge Standard of Water Pollutants for Pulp and Paper Industry (GB 3544-2008).The treatment cost of the advanced process was about 1.01 yuan/m3, in which the chemical cost was 0.58 yuan/m3 and accounted for 56.98%.
