摘要：

针对石化厂炼油废水回用至锅炉补给水的节水技术进行了工艺研究．经二级生化处理后的废水，再经过直流絮凝和超滤去除悬浮物、降低浊度后，完全能够满足下游反渗透的进水要求，并最终实现整个回用水系统的可靠运行．

Abstract:

A 2-month pilot study for the reuse of refinery wastewater from petrochemical plants has been carried out to verify the process of “Multimedia filter +ultrafiltration +Reverse Osmosis”. The results show that the turbidity and SDI of ultrafiltration permeation are low enough to meet the requirements of the feed water of the following reverse osmosis.

Key words: refinery wastewater, ultrafiltration, reverse osmosis, membrane separation
