【 摘 要 】

In this paper, surface water of mining cities is pretreated by biological contact oxidation process filled with modified suspending biochemical packing, the characteristics of natural biofilm and the removal of organic pollutants, ammonia nitrogen, total nitrogen and turbidity in surface water were studied. The results show that the structure of mature biofilm is stable and the microbial population appears diversity, and the system has good removal effect on ammonia nitrogen and total nitrogen during the stabilization period, while the removal of organic pollutants and turbidity is slightly worse, the removal effect of the system on organic pollutants, ammonia nitrogen and total nitrogen is better at higher temperatures; on the contrary, the system has a good removal effect on turbidity at lower temperatures.
