摘要

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。

Abstract: The recovery strategy of sequential biocatalyst addition and the key points during the implementation of bio-augmentation strategy was investigated to rapid recovery of full-scale nitrification system with long-term inhibition in this study, which was difficult to recover through conventional regulations. The concentrations of ammonia, nitrate, nitrous, COD, alkalinity and total phenol were determined after adding high-efficient nitrifying bacteria in the lab-scale and full-scale experiments. Meanwhile, microscopic examination was carried out to analyze the changes of protometazoan animals. The results shown that ammonia concentration decreased significantly and the proto-metazoan animals appeared gradually after adding nitrifying bacteria. For the treatment of real coal chemical wastewater, the full-scale nitrification system can be realized long-term stable operation with the influent total phenol concentration lower than 10 mg/L. According to results, lab-scale experiment can be used as a preliminary reference for the feasibility of the bio-augmentation strategy. Accurate identification of the instability reasons or the inhibitors in full-scale nitrification system was the key point for the rapid recovery of the full-scale nitrification system. Through maximum extent to reduce inhibitor concentration, the nitrification reaction can be established quickly, and then the full-scale nitrification system also realized by using the recovery strategy of sequential biocatalyst addition basis on the conventional regulations.
