Cr (VI) is a toxic heavy metal, causing environmental pollution, using biological methods to Cr (VI) revert to the low toxic Cr (III) has been widely recognized. But the biological reaction rate slow problem, for this issue, a redox mediator accelerate Cr (VI) biological reduction research. Specified below: (1) filter the best mediator and optimize the dosage levels, (2) six impact factors (temperature, pH, glucose concentration, Cr (VI) concentrations of dissolved oxygen, and coexisting ions) for restoring a system, (3) Cr (VI) biological reduction process, the pH,OD and measurement of the redox potential. Experiment results indicates that, five species between body in the AQS accelerated effect most obviously, with between body concentration of increased, Cr (VI) removal rate more large; in six species effect factors in the, Cr (VI) restore with temperature rise and increases, with glucose, and Cr (VI) concentration, and dissolved oxygen of increases and reduced, coexistence ion in the Ca2+, and Mg2+, and SO32-accelerated has Cr (VI) of restore; in Cr (VI) of restore process in the, system of pH and turbidity are gradually increases.
