本文主要介绍江水体中重金属的化学形态及其分布规律，以及在自然条件下和酸性废水排放条件下，表层底泥中重金属形态的转变和释放。在化学形态与水质标准，化学形态与江的污染控制方面作了较深入的探讨。研究结果可用于江或其它河流的重金属污染控制。 This article mainly introduces the chemical forms and distribution rules of heavy metals in the Yongjiang River water body, as well as the transformation and release of heavy metals in the surface sediments under natural conditions and acidic wastewater discharge conditions. In the chemical form and water quality standards, chemical forms and pollution control of the Qijiang made a more in-depth discussion. The results of this study can be used to control heavy metal pollution in the Yong River or other rivers.
