O
and CeO
, as main rare earth oxides, with unique physical and chemical properties have been widely used in catalyst and grinding industry. In this study, the effects of La
O
and CeO
on the anaerobic process were investigated. The biological methane production tests showed that 0-0.05 g/L La
O
and 0-0.05 g/L CeO
enhanced anaerobic methanogenesis process. The result showed maximum specific methanogenic rates of La
O
and CeO
were 56.26 mL/(h·gVSS) and 49.43 mL/(h·gVSS) and, compared with the control, increased 4% and 3%, respectively. La
O
significantly reduced the accumulation of volatile fatty acids (VFAs), whereas CeO
had no similar effect. Dissolution experiments demonstrated that the content of extracellular La in the anaerobic granular sludge reached 404 μg-La/g volatile suspended solid (VSS), which was 134 times higher than that of extracellular Ce (3 μg-Ce/gVSS). The content of intracellular La reached 206 μg-La/gVSS, which was 19 times higher than that of intracellular Ce (11 μg-Ce/gVSS). The different stimulation between La
and Ce
could be attributed to the different dissolution of La
O
and CeO
. The result of this work is helpful to optimize anaerobic processes and to develop novel additives. PRACTITIONER POINTS: Novel anaerobic additives were developed. La2O3 and CeO2 in 0-0.05 g/L enhanced organics degradation and methane production. The addition of La2O3 significantly reduced the accumulation of volatile fatty acids. The solubilization of La2O3 was stronger than CeO2. The promoting effects of low concentrations of La2O3 and CeO2 were derived from dissolved La and Ce. |
