Iron containing sludge resource treatment equipment

Product Introduction

The steel industry and metal products industry require the removal of iron oxide scales on the surface of steel during the production process, and hydrochloric acid is used for pickling. During the pickling process, a large amount of acidic rinse water is generated. Acidic flushing water mainly contains free acids and iron ions. At present, most domestic enterprises adopt the neutralization method to neutralize wastewater and discharge it. However, this method consumes a large amount of lime or alkaline solution and produces a large amount of iron containing sludge with a moisture content of 99% that cannot be treated, causing serious secondary pollution and putting great environmental pressure on enterprises.

This technology is to adjust the pH value of the sludge neutralized by acid washing wastewater from steel pickling, and then enter a multiphase reactor. After a series of chemical reactions, this sludge is converted into iron oxide, which can be magnetically separated and has a total iron content of over 60%, achieving resource utilization. This not only solves environmental problems, but also turns waste into treasure, achieving the recycling and reuse of waste resources
Use.
