- 摘要:
- 以阜新市顺达化工厂的废水为试验水样，通过向废水中投加白云石，其pH达6.5后，废水经过二级蒸发、活性炭吸附以回收利用糠醛。结果表明：在试验条件为90℃，白云石投药量为30 g、活性炭投加量为40 g的最佳条件下，CODCr 浓度从1 630 mg·L-1降到9~15 mg·L-1，可回用于生产工艺，蒸发后液体经过结晶、干燥，得到醋酸钙镁盐环保型融雪剂，实现了糠醛废水和酸物回收利用，工艺简单，成本低，具有推广应用价值。
- Abstract:
- Taking the waste water of Shunda Chemical Plant in Fuxin as experimental water sample, the reuse of furfural was studied by adding dolomite into furfural to make pH reach 6.5.The concentration of COD will drop from 16 300 to 9~15 mg·L-1, after two stages of evaporation and activated carbon adsorption and the treated wastewater could be reused in the process. Evaporated liquid could be made into environmental friendly snowmelt agent (calcium magnesium acetate ) through completion of crystallization and drying. Thus, pollutants in furfural wastewater could be treated and reused. It was featured with simple process, low cost and promotion potential.
