Abstract:

Acid mine drainage (AMD) is of great harm to the environment as it contains rich heavy metal ions such as Copper, Lead, Zinc, and Cadmium. The main causes and harms of AMD is analyzed, and the techniques currently used to treat AMD is summarized and their advantages and shortcomings are analyzed. Moreover, the research progress and development trend of treatment technology for AMD in China and abroad are presented through a brief introduction of new treatment technologies. The necessity and inevitability of developing efficient, low-cost, safe and convenient treatment technology are expounded.

Key words: acid mine drainage(AMD), harmful to environment, water pollution, treatment technology, wastewater treatment
