摘要
采用充水期内交替轮换曝气-厌气及两次进水的方法,对城市污水进行硝化和反硝化脱氮.为了探求最优的操作运行决策,本文对间歇活性污泥法硝化及脱氮过程作模拟分析,讨论了31种运行方案与决策,分析了各种影响因素,提供最适宜的运行方式.采用AN-A-AN-A交替轮换厌气-曝气法进水,在充水结束前实现有机氮、氨氮、氧化氮同步降低的过程,从而获得最优的处理效果.采用两次充水的方法效果比充水期内交替轮换厌气-曝气的运行效果差。
Alternative aeration sequence and influent at twice are applied
in filling time for nitrification and denitrification of municipal waste
water in SBR.The 31 schemes and strategies of nitrification and denitri-
fication are discussed for the operation optimization.The optimum ope-
ration strategy is found in this paper.With AN-A-AN-A operation stra-
tegy in the filling stage, removals of organic nitrogen,ammonia nitrogen,
nitrite nitrogen are carried out simultaneously before the end of the filling
stage.The efficiency of nitrogen removals by influent at twice in filling
time is less than by alternative aeration-anaeration sequence.
