RECOVERY STRATEGY OF SEQUENTIAL BIOCATALYST ADDITION AFTER INHIBITION OF FULL-SCALE NITRIFICATION SYSTEMS: A FEASIBILITY STUDY

  • 摘要: 针对长期抑制且通过常规调控方式难以恢复的工业规模硝化系统,探究菌群流加策略进行快速恢复的可行性及实施过程中存在的关键问题。采取小试试验和工业规模试验结合的方式,投加高效硝化菌,测定出水中氨氮、硝氮、亚硝氮、COD、碱度和总酚的浓度,同时进行镜检,分析其中原后生动物的变化情况。结果表明:投加硝化菌的试验组出水中氨氮浓度均显著降低,原后生动物逐渐显现。针对实际煤化工废水,硝化系统进水总酚浓度宜控制在10 mg/L以下,工业规模硝化系统可以实现长期稳定运行。根据实验结果,小试可以作为菌群流加恢复策略可行性的初步参考依据;准确识别工业规模硝化系统失稳原因或抑制物种类是实现其快速恢复的关键;在常规调控方式的基础上,最大限度的降低抑制物浓度,采用菌群流加恢复策略能够较快的建立硝化反应,进而实现工业规模硝化系统的快速恢复。
