摘　　要：我国北方地区冬季气温低时,污水处理厂生化系统普遍存在去除效率低,氨氮和总氮不能稳定达标的问题。特别是亚铵法制浆废水,具有较高的氨氮、总氮,在低温条件下,生化系统更加难以运行。文章提出了若干运行控制措施,并结合实际验证了有效性,为相关行业生物脱氮运行控制提供经验,确保在低温条件下,氨氮、总氮能够长期稳定达标。When the temperature is low in winter in northern China,the biochemical system of sewage treatment plants generally suffers from low removal efficiency,and ammonia nitrogen and total nitrogen cannot meet the standards stably.In particular,the ammonium sulfite pulping wastewater has relatively high ammonia nitrogen and total nitrogen.Under low temperature conditions,the biochemical system is more difficult to operate.The paper puts forward a number of operational control measures,and verified their effectiveness in combination with actual conditions,providing experience for the operational control of biological denitrification in related industries,ensuring that ammonia nitrogen and total nitrogen can reach the standard stably for a long time under low temperature conditions.
