河道断面氨氮去除及水质提升处理工艺技术应用

Technology and Application of Ammonia Nitrogen Removal and Water Quality Improvement in River Section

文章主要介绍了两种河道断面氨氮去除及水质提升的工艺技术现场应用情况。实际处理水量为3000m^(3)/d,其中沸石氨吸附处理工艺段处理量为2000m^(3)/d,氨氧化工程菌曝气滤池工艺段处理量为1000m^(3)/d。现场实施期间,水质均达到设计要求:氨氮去除率大于40%,且设备出水氨氮≤2mg/L,本实验推荐采用"曝气氨氧化工程菌曝气滤池"作为河道断面氨氮去除、水质达标的主要工艺。

This paper mainly introduces the field application of ammonia nitrogen removal and water quality improvement technologies in two river sections. The actual treatment capacity is 3000 m^(3)/d, in which the treatment capacity of zeolite ammonia adsorption process section is 2000 m^(3)/d, and the treatment capacity of ammonia oxidation engineering bacteria aerated filter process section is 1000 m^(3)/d. During the field implementation, the water quality meets the design requirements: the ammonia nitrogen removal rate is more than 40%, and the ammonia nitrogen in the effluent of the equipment is less than or equal to 2 mg/L. in this experiment, "aerated ammonia oxidation engineering bacteria aerated filter"is recommended as the main process for ammonia nitrogen removal in the river section and water quality reaching the standard.
