摘要

Wastewater at SOHIO's Toledo refinery was sampled every four hours for four successive days in December, 1976. Efflu¬ents from the full-scale system (dissolved-air-flotation [DAF] unit and final clarifier for the activated-sludge unit) and an add-on pilot-scale unit (mixed-media filter and activated-carbon columns) were sampled for analysis of common wastewater para¬meters and trace organic compounds. Grab samples taken every four hours were composited daily. Organics were isolated into acid, base, and neutral fractions. Four-day composites of these daily extracts were analyzed by capillary-column gas chromatog-raphy/mass spectrometry. Some 304 compounds were identified in the neutral fraction of the DAF effluent and removal of these organics by the activated-sludge and add-on treatment units was estimated. Numerous data for the approximate concentration of organic compounds are presented. Common wastewater parameters are also presented for comparison to specific organics concen¬tration data.
