摘要
针对石油化工企业含苯胺的消防污水,利用基于过氧化氢和氯化铁为氧化剂的深度氧化技术,通过氧化、絮凝、过滤和吸附对消防污水进行处理。实验确定氧化剂的投加量为理论投加量,氧化时间1.0h,消防污水pH值为6.86时,絮凝剂最佳使用浓度约为2%,消防污水中苯胺和COD去除率达到99.5%以上,达到了消防污水处理效果。
Aiming at the fire-fighting sewage containing aniline in petrochemical enterprises,the advanced oxidation technology based on hydrogen peroxide and ferric chloride is used to treat the fire-fighting sewage by oxidation,flocculation,filtration and adsorption.When the dosage of oxidant is the theoretical dosage that the oxidation time is1.0 hand the pH value of fire sewage is 6.86,the optimal concentration of flocculant is approximately 2%,and the removal rate of aniline and COD is over 99.5%.
