摘要:
针对湿法提钒工艺排放的含钒废水特点,采用硫酸亚铁作为还原剂,使废水中的高价钒还原,其氧化产物再作为沉淀剂与还原产物反应,使废水中各种形态的钒沉淀.在碱性条件下,生成的Fe(OH)2和Fe(OH)3还可作为絮凝剂加速沉淀,从而达到去除钒的目的.考察了反应时间,搅拌速率,废水的pH和FeSO4的用量等对钒去除率的影响,同时也对去除机理进行了探讨.发现当含钒废水为50 mL时(含钒167.7 mg/L),5 000 mg/L的FeSO4用量为19 mL,搅拌速率为100 r/m,待反应30 min后,再用NaOH将废水的pH调至9.0,处理后的含钒废水中钒的去除率可达96%以上.
Abstract:
A treatment technique for dealing with the vanadium contained water was developed according to the water’s properties. Ferrous sulfate was utilized as reducing agent to reduce high valence vanadium, and its oxidization could react with the reducing product to precipitate vanadium in different valence. Under the alkaline condition, the formed Fe(OH)2 and Fe(OH)3 could be used as flocculant to accelerate the precipitation, thus vanadium in the waste water was removed. The reaction time, stirring speed, pH of waste water and the amount of FeSO4 were examined on the removing effect of vanadium, meanwhile the removing mechanism was also discussed. It is found that when the waste water is 50 mL(V: 167.7 mg/L), 19 mL 5 000 mg/L of FeSO4 is added to the water and after reaction for 30 min at stirring speed 100 r/m, then NaOH is used to modulate the pH to 9.0 of the water, the removing rate for vanadium is up to 96%.
