Abstract: In order to reduce the N2O production in denitrifying phosphorus removal process,the acetate, the mixture of acetate and propionate, and the propionate were used as carbon sources to study their effects on N2O production in reaction systems. The results showed that in denitrifying phosphorus removal process, the production of N2O was the most with acetate as carbon source, the second with the mixture of acetate and propionate as carbon source, and the lest with the propionate as carbon source. When use the acetate, the mixture of acetate and propionate, and the propionate as carbon sources, the ratio of N2O production to the total nitrogen(TN)removal were 8.67%, 1.48% and 0.72% respectively. Different carbon sources resulted in different denitrification process. The ratio of nitrate reduction to nitrite reduction(N1/N2)in propionate system was the lowest, which indicated that there were a few of nitrite accumulated with the propionate as carbon source. At the same time, PHV was the main composition in total PHA in the mixed acid and propionate system. The increasing content of PHV declined the N2O production. In conclusion, using propionate as carbon source in denitrifying phosphorus removal systems had a significant advantage to reduce the production of N2O, while the effect of this process on removal of nitrogen and phosphorus still needed to be further optimized.

Key words: N2O, denitrification enzyme activity, denitrifying phosphorus removal, carbon source, PHA
