The Analysis and Evaluation of Heavy Metal Pollution in Wastewater of Tungsten Mine Area
Abstract:
A systematic research has been presented to the situation of heavy metal pollution in the wastewater which flows through the mining area, tailings area, farmland and rive in a tungsten mine area of Ganzhou. The content of Cu, Pb, Zn, Cd in the wastewater sample had been determined through directly inhalation by flame atomic absorption spectrometry(FAAS). While the content of Cr, Ni in the wastewater was also determined after the collected wastewater sample had been adjusted to pH<2 with nitric acid. The results show that Pb, Zn is the main pollution factors in the region. The pollution in the mining area is the most serious. It is a bit lower in the tailings area than in the mining area. The content of Zn in the farmland has exceeded the standard. And the water in the river that closed mining area is normal. The mining area and tailings area is not suitable for the cultivation of edible plants. Cement ditches should be set up for the wastewater which flows through the farmland
