石化高盐废水深度处理技术研究进展

The study progress of advanc ed treatment technology on petrochemical high salinity wastewater

随着国家环保政策的日益严格和企业节水减排工作的深入实施,无论是上游的油气田开采废水、煤化工废水,还是炼化企业的反渗透浓水,都面临高盐废水的达标排放问题。针对高盐废水的深度处理和达标排放问题,从高盐废水的深度处理回用角度出发,详细介绍了目前研究较多的高盐废水的浓缩技术:蒸发法、膜脱盐法、正渗透和电渗析等,探讨了各处理技术目前的应用现状和应用前景,并对高盐废水的处理前景进行了展望。

With the increasingly strict environmental policies and thorough implementation of the water-saving and emission reduction work in enterprises,oil and gas field wastewater,wastewater from coal chemical industry and concentrated water of RO from petrochemical enterprises are all faced with the discharge up to the standard. At present,many enterprises and districts increase the salt limits of the sewage discharge standards,and limit the arbitrary discharge of high salinity wastewater,so it is very clamant exploring effective technology to solve the problems of high salinity wastewater treatment and discharge. The article investigated the application status and prospect of correlative treatment technology on high salinity wastewater to provide a reference pointing at advanced treatment of high salinity wastewater
