中文摘要：
为了明确磷矿粉在Pb／Zn污染土壤修复领域的研究现状，根据大量国内外文献中有关磷矿粉在土壤环境修复方面文献的相关报道，对磷矿粉修复Pb／Zn污染土壤的机理进行了总结，归纳了磷矿粉的改性方法．分析结果表明：磷矿粉是一种具有工程应用前景的重金属污染土壤修复剂，具有成本低廉、环境友好等优点；磷矿粉主要通过吸附和沉淀等方式固化土中的重金属，进而达到修复重金属污染土的目的；有关磷矿粉的实际工程应用报道还相对较少；关于磷矿粉与Pb／Zn污染土壤的相互作用机理尚缺少进一步研究，有待加深开展此方面的研究工作．
英文摘要：
In order to acquire the research status of remediation of Pb/Zn contaminated soil with modified phosphate rock, a large number of literatures on soil remediation with phosphate rock are reviewed to study the interaction between phosphate rocks and heavy metal Pb/Zn. In addition, the approaches to modifying phosphate rocks are summarized. The results show that phosphate rock is a low-cost, environment friendly soil additive which has a great potential to remedy heavy metal contaminated soil in engineering. The interaction mechanism between phosphate rock and heavy metal contaminated soil still needs to be further investigated. Phosphate rocks can be used to solidify heavy metals in soils through absorption and sedimentation so as to depollute the soils polluted by heavy metals. The application of phosphate rocks in engineering is seldom reported, not to mention studies on the interaction mechanism between phosphate rocks and Pb/Zn contaminated soils. Therefore, this area needs to be further studied.
