Experimental study of organic wastewater treated by two-phase anaerobic

The results of experiment on wastewater with high pollutant concentration from Pharmaceutical industry in reactor designed based on two-phase anaerobic principles, treated wastewater of each phase being analyzed with GC-MS, show that instead of reduction in organic materials after two-phase anaerobic reaction, some in-process products resulting from hydrolyzation and acidification emerge because the acidifier discomposes, compounds composed of big molecule defying degradation into those with small acid molecule easy to degrade, which makes wastewater more subject to biochemical treatment, and after the final treatment of reactor producing methane, species and contents of compound contained in treated wastewater are obviously reduced.
