Method of Biological Wastewater Final Treatment Using Bioremediation in Northern Khabarovskiy Krai

The article presents the results of experimental research for final treatment of gold mining enterprise waste waters using water lentil (Lemna minor) of (Lemna L. ) genus, (Lemnactat S.F. Gray) family, and common red grass (Phrágmites austrális (Cav.) Trin. Ex Steud.).
