摘要

Pickling waste liquid of the steel industry is included in National Hazardous Wastes Catalogue because of its high corrosion and large discharge. The techniques for treating pickling waste liquid (H2SO4) in steel industry is summarized. The advantages,disadvantages and applied ranges of all kinds of control technologies are comparatively analysed. The research trends of techniques for treating pickling waste liquid (H2SO4) are the resource reclamation technologies in future which is pointed out in the paper.
