Pilot Plant Studies of Biological Phenol Degradation from Industrial Effluents.
Abstract
A trickling filter pilot plant was operated to biologically degrade spent phenol paint stripper from building 507 at the Hill AFB Air Logistic Center in Ogden, Utah. The parameters studied were temperature, pH, diammonium phosphate concentration, air flow, influent flow rate, and phenol concentration. Also, series flow, recirculation, and a flooded reactor bed were tested. The pilot plant was operated successfully over a broad range of parameters and phenol removal was demonstrated at concentrations up to 2100 ppm of phenol. The microorganisms degraded phenol at a constant rate related to phenol concentration, and they exhibited physiological stability to the parameters tested. A respirometer test apparatus was used to screen the temperature, pH, and diammonium phosphate and phenol concentrations. The effects of the concentration of chromium and cadmium and those of mixed phenols on the respiration rate were also evaluated with the respirometer. Keywords: Solvent degradation; Waste minimization; Phenolic wastewater.
