ABSTRACT
Algae can increase pH and dissolved oxygen via photosynthesis and affect the wastewater treatment
performance of high-rate algae ponds (HRAPs). Nine laboratory-scale HRAPs divided into three groups
were constructed to treat synthetic wastewater via six-month experiments. Higher algae concentrations
in the influent of HRAPs effectively promoted the wastewater treatment performance. Seasonal variation
had a significant impact on algal growth. Summer tests exhibited a higher reduction of pollutants than
autumn tests. The high-influent algae concentration group in summer (HRAP-A) largely reduced the
TN by 52.7±3.0%, TP by 90.3±1.0%, and dissolved chemical oxygen demand (DCOD) by 99.0±1.0%.
It outperformed the low influent algae concentration group in summer (HRAP-B) and was significantly
higher than the high influent algae concentration group in autumn (HRAP-C). The appropriate operation
and design of HRAPs contributed to efficient wastewater treatments.
