基于FeCo2O4/g-C3N4/CA的光电协同去除小球藻影响因素研究
Influencing Factors of Photo-electric Synergistic Removal of Chlorella vulgaris Based on FeCo2O4/g-C3N4/CA
摘要
Abstract
The frequent outbreaks of harmful algal blooms pose serious threats to aquatic ecosystems,water environments,and human health.Traditional algae removal technologies have certain limitations,whereas photo-electric synergistic,as a novel technology that efficiently combines photocatalysis with electrooxidation,can compensate for the deficiencies of traditional algae removal methods.We take Chlorella vulgaris as a model organism and uses photoelectric synergistic catalytic technology for algal removal experiments.We investigated the influence of different doping ratios of FeCo2O4,current density,electrolyte concentration,catalyst dosage and algal biomass on the chlorophyll a removal rate.The results showed that the best algal removal effect was achieved at higher current density,higher electrolyte concentration,higher catalyst dosage and lower algal biomass.When the current density is 2.0 mA/cm2,the electrolyte concentration is 0.10 M,and the catalyst dosage is 0.30 g,the removal rate of algal biomass(6.0×106 cells/mL)reaches 93.71%.Therefore,our study can provide scientific basis for the management and control of water eutrophication and algae outbreak.关键词
