Claims (1)

The method of deep biological wastewater treatment is used in the treatment of domestic and urban water and close to it in terms of the composition and amount of pollutants of industrial wastewater. The essence of the invention: waste water is subjected to primary anaerobic settling, where as a carrier of microorganisms (NM) use frame or porous NM in combination with additional NM in the form of clay-containing and chemically active natural lime-containing sedimentary rocks and porous minerals based on potassium aluminosilicate, followed by stabilized sediment removed, and the liquid phase is directed to a two-stage aerobic treatment using porous NM at the first stage in combination with additional NM in the form of clay; holding and chemically active natural lime-containing sedimentary rocks and porous minerals on the basis of potassium aluminosilicates, and on the second stage - frame or porous NM, modified by microalgae in combination with additional NM in the form of clay-containing chemically active natural lime-containing sedimentary rocks and natural porous minerals on the basis of potassium aluminosilicates with the subsequent stage of removal of clarified water, in which to fix microflora use NM in the form of clay-containing and chemically active izvestsoderzhashchih-period sedimentary rocks and natural porous minerals on the basis of potassium aluminosilicate.
