Its performance under actual field conditions, however, remains insufficiently documented. Swelling and heavy-metal adsorption behaviors of PMB and sodium bentonite (NaB) were systematically compared under varied contaminant solutions. The hydraulic performance of polymer-modified bentonite-sand (PMB-S) and sodium bentonite-sand (NaB-S) mixtures was evaluated. Furthermore, the feasibility of using in situ phosphate mine waste as a substrate material in PMB-based barriers was discussed. Results show that across the pH range of 2 to 12, PMB always maintains a free swelling index greater than 50 mL/2 g, significantly higher than that of NaB. Additionally, its adsorption performance for Pb2+ and Cu2+ is superior to that of NaB, with the removal rates increasing by 58.42% and 61.31%, respectively, particularly in acidic environments. The hydraulic conductivity of PMB-S is significantly lower than that of NaB-S, and may consistently achieve values below 1×10-8 cm/s in most contaminated environments. The mixtures of PMB with three phosphate mine wastes have comparable hydraulic performance to PMB-S, confirming its feasibility as a barrier material. Furthermore, field demonstrations in alkaline lead-zinc and acidic phosphogypsum tailings validate the robust hydraulic and contaminant barrier properties of PMB-S under actual conditions., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=null, pdfFileSize=null, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=null, fund=null, authors=null, authorsList=null), CN=ArticleExt(id=1259474419676754279, articleId=1259474417290195292, tenantId=1146029695717560320, journalId=1259198796492718097, language=CN, title=聚合物改性膨润土-砂混合物防渗工程应用初探, columnId=1259474419483816292, journalTitle=土木工程学报, columnName=岩土力学与地基基础, runingTitle=null, highlight=null, articleAbstract=聚合物改性膨润土(PMB)因其低渗透性和优异的抗盐能力，已成为工业固废防渗领域的研究热点。然而，目前关于PMB在真实尾矿库服役环境中的研究与应用仍较有限。系统比较PMB与钠基膨润土(NaB)在不同污染环境下的膨胀性和重金属吸附性能，评估聚合物改性膨润土-砂(PMB-S)与NaB-砂(NaB-S)混合物的渗透性能，并进一步探讨磷矿现场弃渣作为基质材料与PMB混合用于防渗的可行性。结果表明，PMB在pH 2～pH 12范围内自由膨胀指数始终>50 mL/2 g，显著高于NaB；同时，其对Pb2+和Cu2+的吸附性能也优于NaB，尤其在酸性环境下，去除率分别提高58.42%和61.31%。PMB-S混合物的渗透系数明显低于NaB-S，且在多数污染环境下可稳定低于1×10-8 cm/s。PMB与三种磷矿弃渣混合物的渗透性能与PMB-S接近，验证弃渣作为防渗基质材料的可行性。通过在强碱性铅锌矿和强酸性磷石膏尾矿库开展原位防渗工程示范，进一步验证PMB-S在实际工况下的防渗与污染阻隔性能。, correspAuthors=杨微, authorNote=杨微(1986—)，女，博士，教授。主要从事环境岩土工程的研究。
