摘　　要：为强化煤化工污水处理厂生化系统低温脱氮效能,针对几种不同特性的硝化菌剂进行小试实验。结果表明:原水水质不稳定,各类菌剂提高生化系统氨氮去除效率的能力各不相同。低浓度下各类菌剂均具有较好的协同处理效果,高浓度下低温硝化菌剂和化工硝化菌剂被不同程度地抑制,只有混合硝化菌剂在不同原水氨氮浓度下均保持良好的协同处理效果。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.
