WASTEWATER TREATMENT METHOD WITH BIOMASS PRODUCTION Russian patent published in 2023 - IPC C02F3/02 C02F3/32 C12N1/00 

FIELD: biotechnology.

SUBSTANCE: method of wastewater treatment with biomass production is proposed, which includes pumping carbon dioxide produced during the oxidation of biological wastewater pollution in a separate container through a suspension of photosynthetic organisms in a liquid medium located in a separate tank under the rays of light with the production of exhaust oxygen and biomass production, and in advance empirically determine the required volume of wastewater and number of photosynthetic organisms. The levels of photosynthetic organisms in the liquid nutrient medium and wastewater, respectively, in the tank and vessel are maintained automatically; the biomass of photosynthetic organisms is taken from the tank, and purified water - from a separate section of the tank; oxygen is pumped from the tank above the level of the liquid medium to be supplied to the tank by a dosing pump with control oxygen concentration. Control of the concentration of carbon dioxide is carried out by increasing or decreasing the supply of wastewater to the tank.

EFFECT: invention provides biological wastewater treatment due to oxygen obtained by photosynthetic organisms.
