摘　　要：宁夏某焦化厂XY55495C焦炉配套的焦化废水处理系统,采用强化生物脱氮深度处理工艺,自建成投运以来,整个系统运行日趋稳定,出水水质满足《城市污水再生利用·工业用水水质》(GB/T19923-2005)敞开式循环冷却水系统补充水水质标准,该工艺不仅极大的减少了废水中污染物的排放量,而且处理后的水全部回用,大大地节约了水资源。本文论述了强化生物脱氮+深度处理的工艺原理,分析了达标回用的可行性,并进行了相关的验证。The enhanced bio- denitrification biological and TNC process were used in the coking wastewater treatment system in the Ningxia coking factories. At present,the coking wastewater was operated steadily and met the national discharges standard GB / T19923- 2005 and standard wastewater was reused. This paper introduced the princle of the enhanced bio- denitrification biological and TNC process. The quality of the standard wastewater was measured and verified that it could met the national discharges standard.
