METHOD OF BIOLOGICAL SEWAGE WATER PURIFICATION AND DEVICE FOR ITS REALISATION Russian patent published in 2015 - IPC C02F3/02 C02F11/04 C02F11/14 

FIELD: chemistry.

SUBSTANCE: method of biological purification of sewage water with active silt is realised with application of biologically active substance, which is represented by powder-like substance UWDM-1, containing rotaxane molecules and binuclear copper complex, in amount, providing its concentration in bioreactor, equal 10^-6-1·10^-10 mg/dm³. Device for method realisation consists of hermetic case (1) with branch pipes of input (2) of sewage water, discharge (3) of purified water, discharge of biogas (4), coaxially located in case hollow central tube (5) with branch pipes of supply (6) and discharge (7) of heat-carrier, means for supply of biologically active substance. Means for supply of biologically active substance is made in form of mixer with drive (8), provided with dosing devices (9) in upper part, and in lower part connected by means of pipeline (1) with upper part of case (1). Central tube (5) is separated by not less than two transverse nets (11), covered with porous material (12). Holes (13) of nets (11) are located with displacement relative to each other.

EFFECT: increased efficiency of purification.
