【 摘 要 】

A laboratory experiment of biological treatment has been performed with multilevel bio-contact oxidation system to treat the actual automobile painting wastewater pre-treated by physicochemical processes. The influence of three important process operating parameters (namely, hydraulic retention time, dissolved oxygen concentration, organic loading) on treating efficiency of multilevel bio-contact oxidation system has been investigated, and the optimum process operating parameters have been determined.
