| Abstract |
Biological phosphorus removal is characterized by complex interactions between different intracellular components of energy as PHA. Therefore, fundamental understanding of the behavior of the intracellular components and their influence on the removal of phosphorus is essential before control strategies to stabilize the proper process. The purpose of this study is to investigate relationship between release of phosphorus and synthesis of intracellular storage polymer. Mass of stored intracellular storage polymer was 21.2 ㎎ PHA/L, 28.8 ㎎ PHA / g MLSS. And phosphorus release/ intracellular storage polymer synthesis rate was 1.8545 ㎎ stored polymer/㎎ Phosphate. In the aerobic phase, mass of PAOs synthesis is 49.37 ㎎ PAOs/L. And PAOs fraction was 6.7-6.9%. Thus intracellular storage polymer synthesis by PAOs is calculated as 493㎎ PHA / g PAOs. |
