Magnetic carrier for treating ore wastewater and application

The invention discloses a magnetic carrier for treating ore wastewater and application. According to the method, the magnetic carrier is prepared through microwave treatment, strong alkali activation and surface modification of the magnetic material, magnetism is enhanced, surface active sites are increased, the adsorption and flocculation capacity on fine particles in wastewater is enhanced, the dosage of chemicals is reduced, and mineral wastewater can be treated more environmentally and efficiently. According to the method, the magnetic material is wide in source, low in cost and recyclable, the pain points of large reagent residue and high return water turbidity of the ore wastewater are eliminated, and sustainable development of zero discharge of the wastewater is assisted. 本发明公开了一种处理石矿废水的磁性载体和应用。本方法通过对磁性材料"微波处理+强碱活化+表面改性"的方法制备磁性载体，磁性增强、表面活性位点增多，对废水中微细颗粒吸附絮凝能力增强，药剂用量降低，可更加绿色高效处理石矿废水。本方法磁性材料来源广、成本低，可循环利用，消除石矿废水药剂残留大、回水浊度高的痛点，助力废水"零排放"的可持续发展。
