Abstract:

Two different BNR processes were operated to remove nutrients from low-organic strength sewage when AFLFW was added as an external carbon source. In a four-stage BNR process with AFLFW, average removal efficiencies of CODcr, T-N, T-P were 90 - 97%, 60 - 77%, 2 - 67%, respectively. The Ss fraction and Xs fraction were 10%, 22% of COD in domestic sewage, respectively. With this sewage, average removal efficiencies of SCODcr, T-N, T-P were 88 - 93%, 70 - 74%, 63 - 68%, respectively. But breakdown of EBPR mechanism was observed at long SRT of 50 days. In this case, the average composition of PHB, PHV, PHH, PHO, PHD, PHDD, PHTD in biomass were 24%, 41%, 18%, 10%, 5%, 2%, and 0%, respectively. In the SBR system supplied with glucose, nitrification and denitrification efficiencies also increased as SRT increased. When SRT was 10 and 15 days, nitrification and denitrification efficiencies were 100% and 70%, respectively. As SRT decreased from 15 to 5 days, EBPR activity of microorganisms increased.
