摘要
针对某石油化工厂含盐废水浊度低、结垢离子含量高、有机物含量高、水质水量波动大等特点,采用絮凝沉淀+纤维过滤器+超滤+反渗透组合处理工艺,出水水质达到《石油化工给水排水水质标准》(SH 3099—2000)的给水标准,实现了出水回用于生产给水、全过程封闭处理。运行实践表明,该工艺具有占地面积小、运行费用低、处理效果稳定的特点,适用于石油化工厂含盐废水处理。
In view of the characteristics of low turbidity, high content of scale-forming ions, high content of organic matter and large fluctuation of water quality and water quantity, a combined process of flocculation sedimentation, fiber filter, ultrafiltration, reverse osmosis was applied to treat salt-containing wastewater in a petrochemical plant. The effluent reached the water supply standard in Water Quality Standard of Water Supply and Drainage in Petrochemical Industry ( SH 3099 - 2000), thus realizing the whole process of closed treatment of water supply for production. The operation showed that the process had the characteristics of small footprint, low operating cost and stable treatment effect, which could be used to treat salt-containing wastewater in petrochemical plant.
