Study on the efficacy of microalgae-bacteria consortium on the treatment of nano fracturing fluid.
This paper studies the treatment effect of microalgae-bacteria consortium on fracturing flowback fluid containing nano-TiO2. The research specifically assessed varying concentrations of nano-TiO2 (0, 5, 15, 30, 60 mg) on biomass production and pollutant degradation during the algae-bacteria consortium's treatment of fracturing flowback fluids. The experimental results demonstrate that the growth of microalgae and bacteria was most favourable in the water sample containing 15 mg of nano-TiO2. After 7 days of incubation, the cell concentration of Chlorella attained 1.04×106 cells/mL, while the bacterial density reached 1.84×106 cells/mL. The presence of nano-TiO2 in wastewater affects the ability of microorganisms to absorb pollutants. Notably, the sample containing 15 mg of nano-TiO2 showed the highest removal of organic matter and ammonia, reaching 46% and 55%, respectively.
