摘要
本文结合东河水文与理化特征对水团追踪试验结果加以探讨。结果表明,悬浮物是重金属重要载体。悬浮物的存在可使水相中重金属在较低pH值条件下向固相迁移,东河中pH值较高有利悬浮物对重金属的吸附.水中重金属的沉淀反应均由碳酸盐控制,碳酸盐沉淀的生成是重金属从水相向固相转移的主要形式之一.
Incorporating with the hydrological characterics and the physico-chemical property of Tunghe, a theoretical approach has been made to the result of water mass tracing experiment. It was shown that the suspended matter is the major carrier for heavy metal and heavy metals in water may transfer into solid phase under low pH. The Tunghe water with higher pH, facilitates the adsorpiton of heavy metal on suspened matter and the precipitation reaction is controlled by carbonate.
