one anoxic-aerobic Moving Bed Bio-film Reactor combined with membrane (MBBR) was used to treat a kind of synthetic leather wastewater, when the value of BOD/TN was controlled from 0.8 to 1.5, about 83.6% of ammonia nitrogen, 61.5% of total nitrogen, 87.4% of nitrate nitrogen, was averagely removed respectively, when the concentrations of total nitrogen, ammonia nitrogen, or nitrate nitrogen was maintained about below 200 mg/L, its removal efficiencies were increased gradually. The results
