| 摘 要： | 堆肥是有机废弃物资源化的产物,利用堆肥修复土壤的金属污染有着重大意义.堆肥可通过直接与金属产生氧化还原作用、沉淀作用、吸附作用或间接改变土壤理化性质如酸碱度,氧化还原电位等降低土壤金属的生物有效性和移动性,但具体修复效果因土壤、金属、堆肥三者性质的不同而差异甚大.本文对国内外利用堆肥修复土壤金属污染的研究进展进行了综述,指出了理论研究和实际修复中存在的一些问题,并对其发展前景进行了展望.

| Abstract: | Utilization of compost in the remediation of metal-contaminated soils has great potential since compost is the recycled product of organic solid waste. Compost may reduce the bioavailability and/or mobility of metals via various direct processes such as redox, precipitation and adsorption, and indirect impacts on soil properties including pH and Eh. The alleviating effect varies with the types and natures of soil, metal and compost. This paper reviews the recent advance in the studies on the remediation of ... |
