印度政府决定根据其亚穆纳行动计划（雅普）在亚穆纳河流域启动一个项目，实施16个全尺寸的上流式厌氧污泥床（UASB）反应器（总容量为598，000 m3/d）。一个抛光池称为最终抛光单元（FPU）用于后处理。本文评估了印度气候条件下，全尺寸UASB反应器和抛光池组合系统的污水处理效率。结果表明，从污水处理厂（STP）调查的流出物未能符合适用的排放标准的BOD，SS和粪大肠菌群的去除。因此，建议进行适当的操作和维护，如去除剩余污泥和浮渣，以提高处理效率。此外，还需要训练有素和经验丰富的工人以科学的方法沿着操作和维护系统。
The government of India decided to launch a project to implement 16 full-scale Upflow Anaerobic Sludge Blanket (UASB) reactors (with a total capacity of 598,000m3/d) in the Yamuna River basin under its Yamuna Action Plan (YAP). A polishing pond called the Final Polishing Unit (FPU) was utilized for post-treatment. This paper evaluates the sewage treatment efficiency of the combined system of full-scale UASB reactors and polishing ponds under Indian climatic conditions. Results have shown that the effluent from the sewage treatment plants (STPs) investigated failed to comply with applicable discharge standards in terms of BOD, SS, and fecal coliform removal. Therefore, it is proposed that such proper operation and maintenance as removing excess sludge and scum be conducted in order to increase treatment efficiency. Moreover, trained and experienced workers are also required to operate and maintain the systems, along with a scientific approach.
