为了解决硫化砷渣对环境的污染，采用了单因素分析法，研究了飞灰、三氧化二铁、PFS、磷酸钠、硫酸亚铁和水泥对硫化砷渣的固化/稳定化效果，研究结果表明：当飞灰加入量为硫化砷渣质量的9倍、水泥的加入量为硫化砷渣质量的4倍、三氧化二铁加入量为硫化砷渣质量的20%、磷酸钠加入量为硫化砷渣质量的10%时，对处理后的样品使用HJ/T 299—2007《固体废物浸出毒性浸出方法硫酸硝酸法》浸出，浸出液中砷的质量浓度为1.12 mg/L，浸取液的pH值为11.5，达到了危险废物填埋污染控制标准。

The fly ash, ferric oxide, PFS, sodium phosphate, ferrous sulfate and cement were investigated by single factor analysis in order to solve the environmental pollution of arsenic sulfide. The results showed that:under the condition that the weight of fly ash is 9 times of arsenic sulfide, the weight of cement is 4 tmies of arsenic sulfide, the weight of ferric oxide is 20%of arsenic sulfide, sodium phosphate is 10%of arsenic sulfide, the leaching concentrate of arsenic is 1.12 mg/L, the pH of lechate is 11.5, by the leaching standard" HJ/T299—2007 Solidwaste-Extraction procedure for leaching toxicity-Sulphuric acid&nitric acid method", the result of which meets the hazardous waste landfill pollution control standard.
