Project of Treating Comprehensive Wastewater of Chemical Industry Park by Anaerobic/Aerobic Bio-Contact Oxidation Process

The process parameters and operation effect of the treatment of comprehensive wastewater of chemical industry park by anaerobic/aerobic bio-contact oxidation process was introduced. This provided a reference of application. Taking a project as an example, process flows, parameters and the size of structures were introduced. Combining with treatment effect, the design features were discussed. The practical operation result showed that the effluent treated by the baffled submerged bio-film process could meet the requirement of classⅡ of the “Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant” (GB18918-2002).
