METHOD FOR THE BIOLOGICAL PURIFICATION OF WASTEWATER

摘要

The invention relates to the biological purification of wastewater and can be used in municipal engineering, and in various branches of the industry and agriculture for purifying domestic, industrial or composition-similar wastewater. The invention first comprises processing the wastewater in a preliminary aeration tank. After the preliminary aeration tank, the wastewater is subjected to mechanical purification. The flow is then fed into a bioreactor and into a settling tank, from which the active sludge is returned to the bioreactor and to the preliminary aeration tank so as to form a closed-loop industrial cycle for the purification of wastewater. The method can be used for automating the wastewater biological-purification process due to the closed-loop industrial cycle, and for reducing the industrial impact on the environment due to the decomposition of organic substances sorbed on mechanical impurities.
