Preparation method and application of nickel slag-based micro-electrolysis filler material
The invention belongs to the field of environmental protection, and provides a process method for preparing a nickel slag-based micro-electrolysis filler material from solid waste nickel slag, and the nickel slag-based micro-electrolysis filler material is applied to environmental treatment of azo compound type wastewater. The invention discloses a method for preparing a nickel slag-based micro-electrolysis filler material by using nickel slag as a raw material, coal as a reducing agent and sodium carbonate as a transforming agent through a roasting-cooling-grinding process, and the nickel slag-based micro-electrolysis filler material is applied to degradation of azoic compounds in azoic compound type wastewater. The nickel slag-based micro-electrolysis filler material is simple in preparation process and low in cost, the degradation rate of the prepared material to azo compounds in azo compound type wastewater can reach 90% or above, and the environment-friendly purpose of treating waste with waste is achieved.
本发明属于环境保护领域，提供了一种固体废物镍渣制备为镍渣基微电解填料材料的工艺方法，镍渣基微电解填料应用于偶氮化合物型废水的环境治理。本发明公开了利用镍渣为原料，煤为还原剂，碳酸钠为转化剂，以焙烧—冷却—研磨工艺制备镍渣基微电解填料材料，并将镍渣基微电解填料应用于偶氮化合物型废水中的偶氮化合物降解。本发明的镍渣基微电解填料材料的制备工艺简单、成本低，制备材料对偶氮化合物型废水中偶氮类化合物的降解率可达90%以上，实现了“以废治废”的环保目的。
