摘要
为了适应江苏省新的地方排放标准,确保污水氨氮达标排放,中石化金陵分公司经过调研,因地制宜,将新建二级生化曝气池由完全曝气式工艺改为A/O(缺氧/好氧)工艺,该工艺投用后,氨氮去除率达90%左右,污水处理场排水口氨氮含量明显下降,解决了企业总排氨氮达标排放的难题。
In order to meet the new local emission standards in Jiangsu Province and comply with the ammonia nitrogen standard for wastewater,SINOPEC Jinling Company replaced complete aeration process with A/O process for its newly built secondary bio aeration tank.As a result,the ammonia nitrogen removal efficiency reached 90%and the ammonia nitrogen content in wastewater at wastewater treatment plant outfalls was remarkably decreased,thus solving the difficulties of the enterprise in meeting the ammonia nitrogen standard for total emission,making contribution to the emission reduction of the enterprise and protecting the environment.
