摘      要：In this paper, the influence of inorganic salt on aerobic biodegradability of dyestuffs was studied by means of semi-continuous activated sludge method. It was found that: biodegradability of dyestuffs would decrease with the increase of the concentration of NaCl; however, biodegradability in the condition of NaCl = 30 g/L was better than that in the condition of NaCl = 15 g/L; in the three NaCl conditions, biodegradability of tested dyestuffs followed the following order: NaCl = 0 g/LNaCl = 30 g/LNaCl = 15 g/L.
