Abstract

A static granular bed reactor (SGBR) was used to treat swine wastewater at 24 and 16°C. At 24°C, the organic loading rate (OLR) was 0.7-5.4kg COD/m³day and the average chemical oxygen demand (COD) removal efficiency was 88.5%, respectively. Meanwhile, at 16°C, the OLR was 1.6-4.0kg COD/m³day and the average COD removal efficiency was 68.0%, respectively. The SGBR acted as a bioreactor as well as a biofilter. After backwashing, the recovery of COD removal was not a function of an OLR but recovery time, while that of TSS removal was not a function of either recovery time or the OLR. The maximum substrate utilization rate (k_max) ratio was 1.89 between 24 and 16°C, and the half velocity constant (K_s) ratio was 1.22, and the maximum specific growth rate (μ_max) ratio was 4.71. In addition, the temperature-activity coefficient in this study was determined to be 1.09.
