南渡江水质物理指标调查

摘要

The water pollution is getting more serious than ever and supervision and governance of water resources are the key point of environmental protection. In order to understand the content of phenol and anionic surfactants in Nandu river water,water samples of 18 species in different locations were took for the study. The physical and chemical parameters of Nandu River water including dissolved oxygen,pH value,total dissolved solids and other factors were detected by the national standard method. The experimental results showed all physical indexes were at normal levels,the quality of Nandu river water basically was good which had little effect on human and aquatic organism.%当前水污染日趋严重,水资源的监察和治理是环境保护的重点.为了了解南渡江的水质情况,本研究两次在南渡江不同水域各采取水样18个.采用国标法对水体中溶氧量、pH值、温度、总溶解性固体、电导率、挥发性酚和阴离子表面活性剂进行检测.实验调查显示南渡江水体的各项物理指标均处于正常水平,对人类健康和水中生物状态影响不大.
