摘要
采用电化学方法氧化油田污水中的硫离子为硫单质,然后使用聚合氯化铝作为絮凝剂脱硫。考察了絮凝剂加入量、搅拌强度和搅拌时间对絮凝剂脱硫效果的影响,结果表明,当聚合氯化铝质量浓度为0.8 g/L、搅拌速率为100 r/min、搅拌时间为4 min时,絮凝效果最好,出水浊度值最小,pH接近中性。
Sulphur ion in the oilfield wastewater is oxidated to sulphur by electrochemical methods, and then sulphur is eliminated with polyaluminium chloride as flocculant. The effects of the amount of flocculant, stirring speed and stirring time on flocculation are researched. The results show that with the dosage of flocculant of 0. 8 g/L,stirring speed of 100 r/min, stirring time of 4 min, the flocculation efficiency is best, the turbidity is least and pH is close to neutral.
