Abstract

Cultivation of Chlorella zofingiensis and nutrients removal in dairy wastewater were investigated in bench-scale outdoor ponds in winter, South China. The impacts of the two types of pH regulations, 5 similar to 6% CO2 and acetic acid (HAc) on this process were studied. After 6 days cultivation, the removal rates of total nitrogen (TN) and orthophosphate (PO43-) using CO2 regulation were better than those using HAc. The removal rates of PO43- and TN were 97.5% and 51.7%, respectively using CO2 regulation; 79.6% (TN) and 42.0% (PO43-) were obtained using HAc regulation. Higher biomass, protein, sugar content, and stable pH control were found using CO2 regulation. However, significantly higher lipid content (31.8%) was observed using HAc regulation. The dominant differences of fatty acids were the content of C18:1 and C18:3. The growth characteristics and environmental conditions especially during the typical logarithmic phase were also analyzed. (C) 2012 Elsevier Ltd. All rights reserved.
