摘　　要：本篇文章主要针对三种运行模式下的CAST工艺脱氮性能做出相关的研究和分析,三种运行模式分别是常规模式、缺氧好氧模式、缺氧好氧交替模式。经研究结果表明,缺氧好氧交替模式下的氨氮去除率比较高,三种模式都可以实现亚硝酸型的硝化,但是亚硝酸型硝化和温度关联密切,随着温度上升会逐渐消失。本文仅供同行业的其他工作人员作为参考意见。This paper mainly studies and analyzes the denitrification performance of cast process under three operation modes,including conventional mode,anoxic and aerobic mode,and anoxic and aerobic alternative mode.The results show that the removal rate of ammonia nitrogen under anoxic and aerobic alternative mode is relatively high,and the nitrification of nitrite type can be realized in all three modes,but nitrite type can be achieved Type C nitrification is closely related to temperature,and will disappear gradually with the increase of temperature.This article is only for reference of other staff in the same industry.
