摘要 本文以冶炼烟气制备硫酸产生的酸泥为对象进行试验研究,结果表明:酸泥中掺入FMH、KZF、化学添加剂A便能形成固化体;将固化体置于模拟恶劣自然条件中,测出固化体浸出液含砷浓度为0.026mg/L,低于国家排放标准0.5mg/L;SEM显示:试验处理之后的固化体内部整体结构良好;XRD分析表明:固化体中形成了-Al-O-Al-As-、-Si-O-Si-As-、-Al-O-Si-As-化学长链,该类化学结构属于类陶瓷结构,具有化学稳定、高强的特性。

Abstract: The arsenic acid mud was researched which came from the process of producing sulfuric acid with smelting gas in this article. The results showed that acid mud can be solidified with chemical additive A ,FMH and KZF. In the conditions of simulated poor nature ,the concentration of arsenic of solidified body is 0.026 mg/L,and it is lower than 0.5 mg/L of the national emission standard. The SEM showed that the internal structure of solidified body is fine after test. The solidified body is made of Al-O-Al-As-,-Si-O-Si-As- and -Al-O-Si-As- through XRD analysis. The chemical structure belongs to the class ceramic, and has chemical stability and high strength characteristics.
Key words:  acid mud    arsenic solidification    ceramic
