摘要:

陶粒是重金属污染土壤资源化利用有效途径,不仅附加值高,还具有广泛的应用前景。通过文献调研,首先对比分析了中国一些地区的重金属污染土壤原料的化学成分,对重金属污染土壤制备陶粒进行可行性分析;然后阐述了重金属污染土壤制备陶粒的工艺及影响因素,并以铬为例分析了陶粒固化重金属的机理;最后阐述了重金属污染土壤陶粒当前应用方向及未来可能应用的方向,并提出了当前重金属污染土壤陶粒存在的一些问题和展望。结果表明,重金属污染土壤烧结陶粒具有可行性,其烧结过程会受到原料配比和烧结机制等因素的影响,且烧结后的陶粒重金属固化效果好,其陶粒产品当前被运用于建筑领域,而水处理滤料和陶粒支撑剂等也是其未来可能的应用方向。

Abstract:

Ceramsite is an effective resource utilization way of heavy metal-contaminated soil,which not only has high added value but also has a wide application prospect.Through literature research,firstly,the chemical composition of heavy metal contaminated soil in some areas of China was compared and analyzed,and the feasibility of preparing ceramsite from heavy metal contaminated soil was analyzed.Then,the process and influencing factors of preparing ceramsite from soil polluted by heavy metals were expounded,and the mechanism of ceramsite curing heavy metals was analyzed with chromium as an example.Finally,the current application direction and possible future application direction of heavy metal contaminated soil ceramsite were expounded,and some problems and prospects of heavy metal contaminated soil ceramsite were put forward.The results showed that it was feasible to sinter ceramsite in soil polluted by heavy metals,and the sintering process would be affected by factors such as raw material ratio and sintering mechanism.The sintered ceramsite had a good solidification effect on heavy metals,and its ceramsite products were currently used in the construction field,water treatment filter materials and ceramsite proppants were also possible application directions in the future.

Key words: contaminated soil, ceramsite, roast, heavy metal
