摘要
固体废弃物的大量堆积与不当处理已成为威胁土壤生态环境的关键因素。工业、农业和城市生活垃圾中含有的有害物质不仅会改变土壤的理化性质,破坏生态系统平衡,甚至还会影响农作物生长和食品安全。这些固体废弃物通过填埋、降水淋溶和风蚀扩散等途径进入土壤,导致重金属、持久性有机污染物等逐渐积累,危害生态健康。为解决土壤污染问题,物理、化学、生物及生态修复技术已得到了广泛应用,其中,稳定化、植物修复和微生物降解技术在提高修复效率、降低二次污染方面具有较大优势。因此,研究固体废弃物对土壤的影响及科学修复策略,有助于提升土壤环境质量,促进资源循环利用,推动生态可持续发展。
The accumulation and improper disposal of solid waste have become important factors threatening the soil ecological environment.Harmful substances in industry,agriculture and municipal solid waste can change the physical and chemical properties of soils,disrupt the balance of ecosystems,and even affect crop growth and food safety.Different types of solid waste enter the soil through landfills,precipitation leaching and wind erosion diffusion,resulting in the accumulation of heavy metals and persistent organic pollutants and endangering ecological health.In order to solve the problem of soil pollution,physical,chemical,biological and ecological remediation technologies have been widely used,among which stabilization,phytoremediation and microbial degradation technologies have great advantages in improving remediation efficiency and reducing secondary pollution.Therefore,studying the impact of solid waste on soil and scientific remediation strategies will help improve soil environmental quality,promote resource recycling,and promote sustainable ecological development.
