新疆喀拉通克铜镍矿尾矿周边盐碱土MICP稳定重金属工程工艺与示范效果（2021-2023）

示范工程位于新疆阿勒泰富蕴县喀拉通克铜镍矿乌恰尔尾矿库，示范规模10000平方米，采用了微生物诱导碳酸钙沉淀技术。在土壤修复工程开展前，由第三方机构对原始土壤进行采样；工程结束后，再由第三方机构对工程措施的完成情况及效果开展评估。在土壤修复前与修复后2、5和17个月，参照《农田土壤环境质量监测技术规范（NY/T 395-2012）》进行土壤采样点布设与土样采集。此外，还采集了不同植物的茎、叶等组织样品（家畜可食部分）。以修复后土壤可交换态重金属的钝化率和植物家畜可食部分的重金属达标率作为核心指标，对土壤修复的效果进行评估。The pilot project is located at the Wuqia'er Tailings Pond of Kalatongke Copper-Nickel Mine, Fuyun County, Altay Prefecture, Xinjiang Uygur Autonomous Region, with a pilot scale of 10,000 m², and adopts microbial-induced calcite precipitation (MICP) technology. Before the implementation of the soil remediation project, a third-party institution collected samples from the original soil; after the project was completed, a third-party institution evaluated the completion status and remediation effects of the engineering measures. Soil sampling points were laid out and soil samples were collected in accordance with the *Technical Specification for Monitoring of Agricultural Soil Environmental Quality (NY/T 395-2012)* before soil remediation, and at 2, 5, and 17 months after remediation. In addition, tissue samples (edible parts for livestock) including stems and leaves of various plant species were collected. The soil remediation effects were evaluated using the passivation rate of exchangeable heavy metals in post-remediation soil and the compliance rate of heavy metals in the edible parts of plants for livestock as core indicators.
