摘要: Size fractionation of olive mill wastewater (COD:155000 mg/L; TOC:40000 BOD5:37700 total phenols:4100 absorbance at 395 nm:145 cm -1 ) before and after FeCl3 coagulation, Ca(OH)2 precipitation, electrocoagulation the Fenton process was investigated. Particulate organic compounds were major components COD (54%), TOC (43%), BOD5 (57%), followed by an appreciable soluble size fraction. For phenols parameter, a dominant fraction (54%) appeared in colloidal (5-8 nm) range besides significant particulate (22%) (24%) fractions. coagulation precipitation to be most efficient matter removal, whereas superior phenolics removal. No shift distribution pattern observed chemical treatment since phase-transfer removal mechanism selected processes. The highest inhibition Vibrio fischeri photobacteria decreased solube due elimination phenolic
