BLOCK-MODULAR WASTE WATER TREATMENT PLANT Russian patent published in 2020 - IPC C02F3/00 C02F9/14 

FIELD: water and air purification technology.

SUBSTANCE: proposed invention relates to wastewater treatment facilities and is intended for deep physical-chemical and biological (combined) treatment of industrial and domestic waste water from suspended substances, nitrogen compounds, phosphorus, surfactants and other contaminants. Block-modular treatment structure has sealed housing consisting of separate detachable unified structural units of pipes, interconnected by turning sections and fittings, made in the form of at least one corridor, circular, horizontal, vertical or inclined reservoir using sealed connecting elements, turning sections and fittings. Housing comprises in its volume water-air mixture of active sludge and waste water under excessive pressure to 36 atmospheres. Housing is equipped with waste water or sludge mixture supplying branch pipe, discharging sludge mixture or purified by water branch pipe, aeration system of sludge mixture, agitator of sludge mixture movement, device for injecting gas-air mixture, device for cleaning gaseous emissions, sealed hatch for maintenance of process equipment, pump for recirculation of sludge mixture.

EFFECT: reduction of volume of gaseous substances emissions into atmosphere, possibility of reservoir execution in the form of various technological schemes of biological treatment, as well as increase in efficiency of air oxygen absorption to 80 % and increase in oxidative power from 2 to 4 times, respectively.
