Exploratory study was made on the Guanting reservoir influent treatment by using two-stage BAF at extreme low temperature.The results show that the removal of organics and ammonia nitrogen is seriously inhibited due to low temperature,and the conversion of nitrite into nitrate is no longer a limiting factor of complete nitrification.One possible hypothesis is that the activity of nitrobacter is hi gher than that of nitrosomonas at extreme low temperature.
