Due to the decrease in pH during bioremediation, NaHCO3 was added to buffer the pH changes and promote Cr(III) precipitation. Compared with the addition of NaHCO3 and molasses simultaneously, separate additions were more effective for precipitation. Furthermore, X-ray absorption near-edge structure analysis revealed that after chemical reduction and biological reduction, Cr was attached to the solid medium in the form of Cr(III).By 31 December 2020, Coronavirus disease 2019 (COVID-19) had been prevalent worldwide for one year, a
