摘要
介绍了某化工企业采用序批式活性污泥法SBR工艺处理德士古煤气化高氨氮废水过程中出现的典型案例,分析了SBR在工艺运行过程中出现的污泥解体、老化、发泡、中毒等异常情况产生的原因以及采取的相应对策。
Typical abrormal cases of waste water treatment in a Texaco coal gasification plant containing high concentration of ammonia nitrogen by using SBR process was introduced.The abnormal cases in SBR process,such as sludge decomposition,aging,fouming and poisoning,were analyzed,and the countermeasures were taken.
