Resourceful treatment method for bulk solid waste
The invention relates to the field of solid waste resourceful treatment, and specifically to a resourceful treatment method for bulk solid waste. The method comprises the following steps: preparing anadhesive from the following raw materials in parts by weight: 0-20% of cement, 45-60% of magnesium oxide, 5-10% of sodium sulfate, 5-10% of calcium sulfate, 15-30% of pre-gelatinized starch, 0-5% ofan amide and 0-5% of carboxymethyl cellulose; preparing solid waste raw materials according to the weight percentage of 70-85% of slag and 15-25% of fly ash; doping 5-10% by weight of the adhesive, and uniformly mixing and stirring; adding water of which the weight percentage is 5-15%, and stirring; feeding an obtained mixture into a machine for granulation forming so as to obtain an oval product,wherein the particle size is 20mm; and carrying out natural curing for 7d to obtain a finished product. The building material formed by the method has the advantages that the sintering and drying processes can be omitted, the strength is high, the softening coefficient is high, the durability is good, the stacking density is relatively large, the sintered ceramsite standard can be met, and meanwhile, the production energy consumption and the production cost of enterprises are reduced.
本发明涉及固废资源化处理领域，具体涉及一种大宗固废资源化处理方法，包括如下步骤：粘合剂由以下重量份的原料组成：水泥0～20％、氧化镁45～60％、硫酸钠5～10％、硫酸钙5～10％、预糊化淀粉15～30％、酰胺0～5％、羧甲基纤维素0～5％；将固废原料按矿渣70‑85％、粉煤灰15‑25％的重量百分比配制，掺入重量百分比为5‑10％的上述粘合剂混拌均匀，加重量百分比为5‑15％的水搅拌，上机造粒成型，制品呈椭圆形，粒径20mm，自然养护7d，即可制，该方法成型的建筑材料可以免除烧结和烘干工艺，强度高、软化系数高、耐久性好、堆积密度相对大，能满足烧结陶粒标准，同时降低企业生产能耗和成本。
