Abstract

Abstract:

This paper discusses the treatment of waste acid pickling liquor from steel works by the nanofiltration (NF)membrane, recovery FeSO₄, and the circulation of mother liquor (20%H₂SO₄).The water source is saved and ecological environment is protected.

Key words: nanofiltration membrane, waste acid pickling liquor, waste treatment

摘要：

作者论述了纳滤膜法治理钢厂酸洗废液,回收硫酸亚铁,母液再生后,返回酸洗循环使用。节约了水资源,保护了生态环境。

关键词: 纳滤膜, 酸洗废液, 废液治理
