Small-Scale Research of Nitrifying Bacteria Agents for Coal Chemical Wastewater
To enhance nitrogen removal efficiency at low-temperature of the biochemical system in coal chemical wastewater treatment plant,a small-scale experiment was carried out on several nitrifying bacteria agents.The results showed that all kinds of bacteria agents had good synergistic treatment effect at low ammonia nitrogen concentration.Low-temperature nitrifying bacteria agents and chemical nitrifying bacteria agents were inhibited at high ammonia nitrogen concentration.Mixed nitrifying bacteria agents maintained good synergistic treatment effect at different ammonia nitrogen concentration.
