己内酰胺废水处理过程中ENSBR反应池中的pH值变化规律

Variation of pH in process of caprolactam wastewater treatment in ENSBR

在己内酰胺废水处理过程中,通过对ENSBR反应池中pH值及相关水质参数的变化进行分析,可知pH值变化是由有机物氧化反应、氨化反应、硝化反应、反硝化反应和污泥消解反应等引起的,并且是上述5个反应在不同反应条件下的综合作用结果。

In the process of caprolactam wastewater treatment,by the analysis of ENSBR water quality parameters pH and related analysis of the changes.we can know that pH changes are caused by organic matter oxidation,amination reaction,nitrification,denitrification reactions and reactions caused by sludge digestion,and pH change is the integrative result of the above five reactions under different reaction conditions.
