0122264 Figueroa The objective of this research is to develop an improved biological process for the treatment of wastewater with high phosphorus content. This research focuses on improved understanding of the aerobic sequence of the enhanced biological phosphorus removal (EBPR) process by investigating aerobic metabolism as it relates to generating storage and growth products from poly-b-hydroxybutyrate. The specific tasks of this research are: (1) to establish and operate a pilot-scale sequencing batch reactor to achieve phosphorus removal via a stable, enriched community of phosphate-accumulating organisms (PAOs), (2) to complete a series of batch reactor radioactive carbon tracer studies involving isolation of intracellular components for PAOs during the anaerobic/aerobic EBPR process cycle, (3) to perform mass balances on individual samples from the tracer studies, and (4) to test the applicability of a proposed metabolic mechanism involved in the EBPR process. ***

0122264 Figueroa本研究的目的是开发一种改进的生物工艺用于处理高磷含量的废水。 本研究的重点是提高了解的好氧序列的增强生物除磷（EBPR）过程中，通过调查好氧代谢，因为它涉及到从聚-b-羟基丁酸酯产生的存储和生长产物。 这项研究的具体任务是：（1）建立并运行中试规模的序批式反应器，以通过稳定、富集的聚磷生物（PAO）群落实现除磷，（2）完成一系列间歇式反应器放射性碳示踪剂研究，包括在厌氧/好氧EBPR工艺循环期间分离PAO的细胞内组分，（3）对示踪剂研究中的单个样品进行质量平衡，（4）测试EBPR过程中涉及的拟议代谢机制的适用性。***
