秸秆炭系由植物秸秆(玉米,小麦等)在1200℃高温下气化干馏所得。探讨了不同条件(时间、用量、温度和pH值)下秸秆炭吸附苯酚性能,并对秸秆炭做了不同的改性处理,以提高其吸附性能。结果表明秸秆炭吸附苯酚的最佳条件为:苯酚与秸秆炭用量比例为0.84mg/g,温度35℃,pH=9,最佳吸附时间为5h;用双氧水改性后的秸秆炭吸附过的模拟废水中苯酚含量仅为0.47mg/L。符合GB 8978—1996排放标准。 Straw charcoal from the plant straw (corn, wheat, etc.) at 1200 ℃ high temperature gasification distillation. The charcoal adsorption performance of straw charcoal under different conditions (time, dosage, temperature and pH value) was discussed, and straw charcoal was modified to improve its adsorption performance. The results showed that the optimum conditions for straw charcoal adsorption of phenol were as follows: the ratio of phenol and straw charcoal was 0.84mg / g, temperature 35 ℃, pH = 9, the optimum adsorption time was 5h; The phenol content in simulated wastewater was only 0.47mg / L. In line with GB 8978-1996 emission standards.
