| Abstract: | Flocculent sludge was inoculated at room temperature in SBR reactors R1, R2, and R3 running in gradient, fast, and slow feeding, respectively. Using artificial water distribution as the influent substrate, the impact of the feeding method on the carbon source storage performance and pollutant removal effect was explored. The results showed that the gradient feeding had better internal carbon source storage performance and denitrification effect. After successful startup, the CODin, SNED rates and the average removal rates of TN, COD and TP in R1 were 99.69%, 81.52%, 79.07%, 92.35%, 96.03%, respectively. The average removal rate of TP was ond only to 98.43% of R3. This was because the contribution of PAO to the internal carbon source storage(Ppaos) under slow feeding was the majority(54.41%), while the gradient water Ppaos was only 47.90%. The sludge concentration in R1 was 5 mg/L, which was lower than the 6389 mg/L in R2, but its MLSS/MLVSS was 0.90, indicating that the gradient influent granular sludge had a higher biomass. The EPS analysis results showed that the composition of extracellular polymeric substances(EPS) changed with the change of the feeding method, and the gradient feeding contained higher PN, so the particles were more hydrophobic and the particle structure was more stable. |
