- Abstract
The effect of seasonal temperature fluctuation, organic loading rate shocking and aeration intensity change on the performance of large-scale vegetation-activated sludge process (V-ASP) was evaluated, and effective system regulation measures were proposed. Vegetation characteristics, including photosynthetically active radiation, transpiration ratio and stomatal conductance were also monitored before and after regulation measures implemented. The temperature-proof measures in low winter improved the sludge activity, vegetation characteristics and rhizosphere microorganism function, which helped the effluent COD and NH4+-N meet Chinese wastewater discharge standards stably. By increased the sludge recirculation ratio from 0.5 to 0.75 to resist organic loading rate shocking, the pollutions removal as well as the vegetation activities were improved greatly. As for the instable aeration intensity in varied unit, switch between continuous feeding and pulse feeding effectively enhanced the NH4+-N removal capability.
