碩士 / 國立雲林科技大學 / 環境與安全衛生工程系碩士班 / 101 / High-tech industrial wastewater contains large amounts of phosphorus, but the carbon
source for enhanced biological phosphorus removal (EBPR) system is not
enough(Chuang et al, 2011). For this reason, additional carbon source for the high
phosphorus wastewater treatment, which has large amounts of phosphorus but less
carbon. Acetic acid and propionic acid are common carbon source of wastewater
treatment (Naik et al., 1999; Von Muench et al., 1998). When add acetic acid or
propionic acid for the treatment of high phosphorus wastewater, the cost increased.
Hence it is important to look for supplementary carbon source for EBPR, and the
reduced cost. However, the study of supplementary carbon source was used to PHAs
production, and few for EBPR. The aim of this study is using milk wastewater as the
supplementary carbon source for EBPR.
The result shows that milk wastewater contain VFAs by fermentation, and the
non-VFAs could be uptaked. The P/COD operated at 15/225 and 22.5/225, reators
profile good phosphorus removal efficiency, phosphorus of effluent were complete
removal. The minimum P/COD loading between 22.5/225 to 30/300. On the other hand,
EBPR system using fermented effluent of starch as supplemental carbon sourse also
profile good phosphorus removal. When P/COD is 30/400, system show a typical EBPR
performance. EPBR system can use milk wastewater and starch as supplemental carbon
source, when operate at a appropriate P/COD condition.
The sufficient magnesium in influent is important for EBPR process to sustain
phosphorus removal efficiency. The aim of the study is investigate the effect of
difference magnesium/phosphorus (0.15 mol/mol, and 0.40 mol/mol) in influent, SRT,
and carbon source, on the value of release and uptake of Mg2+/P. Experiment result
indicate that Mg/P in influent and SRT are significant effect factors to the release and
uptake value. Based on the release and uptake value in EBPR process, suggest that
suitable Mg/P of influent is 0.40 mol/mol.
