摘要:生物监测技术通过监测水环境,能够全面反映水环境对生物体的影响,而传统理化监测技术更关注色度、电导率、重金属含量等指标,难以全面反映水环境变化。本文详细分析了生物监测技术的特点、原理及分类,并提出基于生物监测的水体修复方法,为水环境综合治理提供理论依据。

Abstract: Biological monitoring technology can comprehensively reflect the impact of water environment on organisms by monitoring water environment, but traditional physical and chemical monitoring technologies pay more attention to such indicators as chromaticity, conductivity and heavy metal content, which is difficult to fully reflect the changes of water environment. In this paper, the characteristics, principles and classifications of biological monitoring technology are analyzed in detail, and a water body remediation method based on biological monitoring is proposed, which provides a theoretical basis for the comprehensive treatment of water environment.
Keywords: biological monitoring technology; water environment; comprehensive control
