摘要
通过实施江西省某农田土壤中镉、砷污染修复项目,对各修复技术进行比选,并对优选出的稳定化修复技术涉及的钝化药归纳分析。通过小试筛选出合适的药剂种类,中试确定药剂的最佳添加量,再进行工程实施的系统性工艺研究和技术应用。结果表明:该技术在保证修复区增产的前提下实现了污染农田土壤的安全利用,形成了控源降活低吸农产品安全达标生产的修复模式,构建了具有针对性的稳定化农艺调控的联合修复技术体系,可实现重金属污染农田土壤修复、生态建设、经济效益的有机结合。
Through the implementation of remediation project of cadmium and arsenic pollution in farmland soil in Jiangxi,the stabilization remediation technologies were compared and selected,and the deactivators involved in the optimized stabilization remediation technology were summarized and analyzed.The appropriate reagents were selected by laboratory-scale test,and the optimal reagent addition amount was determined by pilot test,and then the systematic process research and technical application for engineering implementation were carried out.The results showed that this technology could realize the safe utilization of contaminated farmland soil on the premise of ensuring the production increase in the remediation area,form a remediation model of source control-deactivation-low absorption-safe production of agricultural products,and construct a targeted stabilization-agronomic regulation joint remediation technology system,and achieve the organic combination of heavy metal contaminated farmland soil remediation,ecological construction and economic benefits.
