METHOD FOR PRODUCING INORGANIC INDUSTRIAL WASTE RECYCLED PRODUCT
To provide a novel method for producing an inorganic industrial material recycled product with reduced hazardous substances, which is environment-friendly and is capable of significantly reducing landfill disposal of industrial waste as compared with a conventional method.SOLUTION: A method for producing an inorganic industrial recycled waste, comprising the steps: mixing an inorganic industrial waste containing an anionic hazardous substance, a calcium-containing waste, and cement so as to obtain a mixture, and solidifying the resulting mixture. It is preferred, in the step of obtaining the mixture, to additionally mix silica-based particles, which can be crushed stone powders. Preferably, in the step of mixing, a hexavalent chromium reducing agent is additionally mixed. Preferably, a chromate forming compound is further mixed in the mixing step. Preferably, a magnesium compound is further mixed.SELECTED DRAWING: Figure 2
【課題】従来の方法よりも産業廃棄物の埋立処分を大幅に低減させることができる環境配慮型の製造方法であって、有害物質が低減された無機系産業廃棄物再生品の新規な製造方法を提供する。【解決手段】無機系産業廃棄物再生品の製造方法は、アニオン系有害物質を含む無機系産業廃棄物、カルシウム含有廃棄物、及びセメントを混合して混合体を得ること、並びに前記混合体を固化することを含む。好ましくは、混合体を得る工程において、さらにシリカ系粒子を混合し、シリカ系粒子は、砕石粉であってもよい。好ましくは、混合体を得る工程において、さらに六価クロム還元剤を混合する。好ましくは、混合体を得る工程において、さらにクロム酸塩形成化合物を混合する。好ましくは、混合体を得る工程において、さらにマグネシウム化合物を混合する。【選択図】図２
