Extensive studies have shown that the relationship between flooding duration and wetland plant biomass is context specific. The underlying mechanisms, however, are uncertain. A likely explanation is that flooding has both direct effects by exerting stress on plants and indirect effects by affecting soil nutrient availability. The net effect would be context‐specific and might depend on season....
The average COD, TN, TP, and NH4+-N elimination rates in a new wastewater treatment plant (WWTP) based on a modified A2/O process were 83%, 72.4%, 93.5%, and 98.6%, respectively, even under conditions of a low C/N ratio and low temperature. Among the four potential denitrifying units, the post-anoxic unit was the least efficient with respect to the removal efficiency. However, the structures of the...
