  • 摘要: 将垃圾焚烧飞灰添加进烧结冷固球团配料进行造球,对冷固小球的成分及强度进行分析,结果表明,添加垃圾焚烧飞灰冷固小球化学组成稳定,重金属浸出毒性远低于危险废物鉴别标准,落下强度较基准期略微降低,但符合运输、贮存的要求。并对添加了飞灰的冷固小球对其后续烧结、冶炼工序的影响进行分析,结果表明,用添加飞灰的冷固小球进行烧结所得烧结矿的转鼓强度、落下强度及常规化学成分较基准期没有太大变化,添加飞灰进行造球、烧结,对其后续冶炼工序的顺行几乎没有影响,所带来的额外的环境污染微乎其微。
    Abstract: MSW incineration fly ash was added into cold-bonded pellet for sintering. The chemical and physical properties of cold-bonded pellet was investigated. Experimental results show that the chemical composition of cold-bonded pellet was stable. The leaching toxicity of cold-bonded pellet is far lower than the leaching toxicity identification standard of hazardous waste. Its drop number is a little lower than that of the pellet without adding MSWI fly ash, but still meets the demand for transporting and sintering. The effect of adding MSWI fly ash in cold-bonded pellet on the sintering as well as smelting process were studied.The results indicated that the drum strength, the falling strength and the chemical composition of the sinter show no significant change when compared to the sinter without adding MSWI fly ash. The hazard-free treatment for MSWI fly ash by metallurgical sintering has little effect on the subsequent process of smelting, and brings very little extra environmental pollution.
