中文摘要:
      目的 用磷酸改性生物炭对包装印刷废水处理,寻找秸秆生物质优化利用新途径。方法 生物炭用磷酸改性,通过正交实验找到制备磷酸改性生物炭的最佳工艺条件,并用最佳工艺条件制备磷酸改性生物炭用于处理包装印刷废水;研究磷酸改性生物炭添加量、吸附时间、pH值对包装印刷废水的吸附量、COD去除率和脱色率的影响,结果 磷酸对生物炭改性的最佳工艺条件:改性时间为4 h,磷酸体积分数为40%,改性温度40 ℃;磷酸改性生物炭处理包装印刷废水的最佳工艺条件:吸附时间为60 min,pH值为8,磷酸改性生物炭质量浓度为0.3 g/L。结论 通过用磷酸来对生物炭改性以提高其对污染物的吸附能力,可用于吸附包装印刷废水中的污染物,用于包装印刷废水的初步处理。
英文摘要:
      The work aims to treat package and printing wastewater by phosphoric acid modified biocarbon to explore a new way for optimum utilization of straw biomass. The biocarbon was modified by phosphoric acid. The optimum process condition was found by orthogonal experiment. The phosphoric acid modified biocarbon for package and printing wastewater treatment was prepared with the optimum process condition. The effects of phosphoric acid modified biocarbon dosage, adsorption time and pH value on adsorption capacity, COD removal rate and decolourization rate of package and printing wastewater were researched. The optimum process condition of biocarbon modified by phosphoric acid was that: phosphoric acid volume fraction was 40%, modified time was 4 h, modified temperature was 40 ℃. The optimum process condition of phosphoric acid modified biocarbon for package and printing wastewater treatment was that: adsorption time was 60 min, pH value was 8, phosphoric acid modified biocarbon dosage quality concentration was 0.3 g/L. Biocarbon modification by phosphoric acid can improve the adsorption capacity of pollutants. It can be used to absorb pollutants package and printing wastewater in the preliminary treatment.
