摘　　要：矿石经选别后会产生大量的尾矿残渣,而其总的回收利用率却很小。尾矿大量的排放堆积将会造成巨大的资源浪费并对土地、水体、自然环境和人畜产生严重危害。实验研究了镁橄榄石尾矿制备的新型生物滤料用于上向流曝气生物滤池(UBAF)处理生活污水的启动规律和处理效果。结果表明,该尾矿滤料对COD、BOD5、NH3-N以及TN的去除率分别达到了80%、70%、90%和50%以上,作为BAF的生物滤料具有良好的市场应用前景。Ore will produce large amounts of tailings after being chosen, but its total recovery rate is very low. A large amount ot blowott anti accumulation oftailings will cause not only a huge waste of resources, but also do serious harm to the land, the water, the natural environment and human. This experiment studied the start rule and effect of a new biological filter which is made by forsterite tailings for the domestic sewage treatment with UBAF. The result turned out that the removal rates of COD ,BOD5 ,NH3-N and TN reached 80% ,70% ,90% and 50% by this tailings filter. BAF will hold a good market prospect when it is used as biological filter
