摘要
为了选择低成本、高效果的处理垃圾渗滤液的吸附剂,本文通过静态吸附试验对比研究了海泡石、炉渣、改性钢渣对垃圾渗滤液中Cr6+的吸附规律,结果表明:吸附平衡时,炉渣对垃圾渗滤液中Cr6+的吸附量最大,为0.001 8mg/g,海泡石次之,为0.001 5mg/g,改性钢渣为0.000 9mg/g;酸性环境及低浓度有利于炉渣、改性钢渣吸附垃圾渗滤液中的Cr6+,且pH值及初始浓度对海泡石吸附垃圾渗滤液中Cr6+的效果影响较小;经综合比较,炉渣吸附性能最为优异。该研究成果可为开发新型吸附剂提供依据。
To reduce the cost of landfill leachate treatment, the static adsorption of meerschaum, slag and activated slag on Cr^6＋ in the landfill leachate were studied. The results showed that when there existed the adsorption equilibrium, slag had the maximum adsorption of Cr^6＋ for 0. 0018 mg/g, the adsorption of meerschaum was 0.0015 mg/g, and the adsorption of activated slag was 0. 0009 mg/g. The acid environment and low concentration were favorable for the absorption of slag and activated slag while pH value and initial concentration had little effect on that of meerschaum. The comprehensive comparison showed that slag had the best absorption. This study can provide proof for developing new kinds of absorption agents.
