| 摘 要： | 氟苯生产过程中产生的废硫酸和废水混合,经隔油、冷却沉淀处理,COD从134.5 g/L降到12.0 g/L,COD去除率91%,酚含量从19 g/L降到3.7 g/L;混合液再经树脂吸附处理,COD平均值在1 g/L左右,COD去除率约92%,苯酚未检出;树脂采用10%氢氧化钠溶液脱附,效果良好,对COD的脱附率达98.5%以上。

| Abstract: | In this paper,the wastewater containing sulfuric acid from producing fluorobenzene was treated and the treating procedure and method including of mixing,removing oil,pretreatment and adsorption was proposed.After treatment with above procedure,the removal efficiency of chemical oxygen demand(COD) in waste solution reaches 91% from 134.5 g/L to 12 g/L,and the concentration of phenol decreases from 19 g/L to 3.7 g/L.And through next adsorbing onto resin,the removal efficiency of COD in waste solution reaches about 92% to 1 g/L without phenol.The desorption efficiency is about 98.5% with 10% NaOH as desorption solvent. |
