The aim of this study was to characterize and evaluate the tratability of wastewater produced in the campus of the Federal University of Ouro Preto (UFOP). The physical-chemical parameters showed the wastewater from the campus had characteristics of typical domestic wastewater, with average values of total BOD, total COD, Kjeldahl Nitrogen and total phosphorus of 300 mg.L-1, 670 mg.L-1, 56 mg.L-1 e 6 mg.L-1 respectively. Only the metals Fe (0,847 mg/L), Al (0,355 mg/L) and Zn (0,389 mg/L) were present in higher concentration, nonetheless, such concentrations were below the thresholds limits for microbial toxicity. The biodegradability tests showed that despite the potential presence of toxic organic compounds, the wastewater could be degraded aerobically (97% efficiency, K1app = 1,73 d-1) and anaerobically (50% efficiency, AME = 0,0579 gDQO CH4/gSSV.d).
