In order to improve the removal efficiency of refractory organic matters in micro-polluted source water, biological manganese oxides (BMOs) were generated in situ in the biological aerated filter (BAF) (BAF 2#), which could oxidize the refractory organic...

A native cyanide-degrading bacterial consortium was isolated from goldmine tailing sediments. Mine tailings are toxic effluents due to their metal?cyanide complexes. The bacterial consortium was able to degrade an initial sodium cyanide concentration ran...
