Research progress on acid coal mine drainage treatment technology
The characteristics and hazards of acid coal mine drainage(ACMD)were introduced,and the treatment methods of ACMD were described.Techniques that could be used for source prevention and process containment were analyzed.The widely used terminal treatment technologies at present were sum-marized,such as the active treatment technology based on neutralization,sulfidation,adsorption and mem-brane technology,and the passive treatment technology based on chemical,biological and chemical-biolog-ical combined method.It was summarized and concluded that the multi-technology combination process was the main trend of engineering application and an effective way for large-scale collaborative treatment of ACMD.Finally,the development prospect of ACMD treatment method was prospected.
