Abstract

Abstract

Algal-derived odor problems in source water reservoirs have become increasingly prominent， severely impairing the sensory quality of drinking water. As an environmentally friendly solid oxidant， sodium percarbonate （SPC） shows considerable potential in algal inhibition and odor control. In this study， three typical odor-producing cyanobacterial species were selected to investigate the oxidative effects of SPC and determine its optimal dosage for algal inhibition and odor control. The results showed that the sensitivity of the three cyanobacteria to SPC followed an order of： Pseudanabaena cinerea > Microcystis aeruginosa > Anabaena. Under both monoculture and mixed-culture conditions， 3 mg/L SPC achieved effective removal of all three species within one day. Although intracellularly bound 2-methylisoborneol （2-MIB） and geosmin （GSM） were released， the dissolved odorants gradually volatilized. Moreover， neither algal density nor odor compounds concentrations increased during subsequent cultivation， indicating effective algal suppression and odor control. Meanwhile， H₂O₂ in the water was completely decomposed within one day， suggesting that SPC does not have persistent environmental impacts. Mixed algal culture enhanced antioxidant capacity， thereby weakening the inhibitory effect of low-concentration SPC （1.5 mg/L） on algal growth. Based on these findings， a dosage of 3 mg/L SPC is recommended for practical applications to achieve more stable and effective algal inhibition and odor control.
