农业土壤重金属污染修复技术研究
摘 要
随着工业化、城市化进程的加速以及农业活动的日益频繁，农业土壤重金属污染问题日益严峻，已成为制约农业可持续发展的重要因素。重金属如铅、镉、铬等，在土壤中难以降解，易通过食物链累积并危害人体健康。本研究聚焦于农业土壤重金属污染问题及修复技术对策，首先概述了土壤重金属污染理论、土壤修复理论基础以及环境风险评估与管理等相关理论，为后续研究奠定理论基础。随后，详细分析了土壤重金属污染对农产品质量、农业生产及生态环境的多方面影响，揭示了其危害的广泛性和严重性。针对这些问题，本研究系统地探讨了农业土壤重金属污染的修复技术，包括物理修复技术、化学修复技术、生物修复技术以及综合修复策略。通过对比分析各种技术的优缺点及适用条件，提出了针对不同污染程度和类型的土壤修复方案。

RESEARCH ON THE REMEDIATION TECHNOLOGY OF HEAVY me taL POLLUTION IN AGRICULTURAL SOIL
ABSTRACT
With the acceleration of industrialization and urbanization and the increasingly frequent agricultural activities, the problem of heavy me tal pollution in agricultural soil is increasingly serious, which has become an important factor restricting the sustainable development of agriculture. Heavy me tals such as lead, cadmium, chromium, etc., are difficult to degrade in the soil, easy to accumulate through the food chain and harm human health. This study focuses on the problem of heavy me tal pollution in agricultural soil and remediation technology countermeasures. Firstly, it summarizes the theory of soil heavy me tal pollution, the theoretical basis of soil remediation and environmental risk assessment and management, laying a theoretical foundation for subsequent research. Subsequently, the effects of soil heavy me tal pollution on the quality of agricultural products, agricultural production and ecological environment are analyzed in detail, and the universality and severity of the harm are revealed. To address these problems, this study systematically explored the remediation techniques of heavy me tal pollution in agricultural soil, including physical, chemical, biological remediation techniques and comprehensive remediation strategies. By comparative analysis of the advantages and disadvantages of various technologies and applicable conditions, the soil remediation scheme for different pollution levels and types is proposed.
