Method for smooth control of aeration intensity and the retention time of the microorganisms in the bioreactor nitrification by measuring the pH reading

摘要

the subject of the invention is a liquid aeration intensity and time control microorganisms in the bioreactor with retention process nitrification by measuring ph value. this method is used to convert ammoniacal nitrogen contained in waste water to nitrite s in water treatment technologies.the way is that the measurement of ph of bioreaktora (1) a comparison of the measured values of ph of the scope of the work of ph, if the ph value is measured in the bioreactor in the accepted range of work in ph (2), then the item ostawia current settings work bioreaktora for aeration intensity and age of sludge without changes (3)however, if the measured ph is below the work adopted bioreaktora (4), then reduces the intensity of aeration and sludge for age based on the criterion, and so if nastawa for sludge age is greater than or equal to the setting for the intensity napowi etrzania (5) is reduced nastawu0119 aeration intensity value of one (6),if not then decreases nastawu0119 sludge age value of one (7) when the ph is above adopted the work of ph (8), then increases the intensity of aeration and sludge age.and if nastawa for sludge age is greater than or equal to the setting for the intensity of aeration (9) that increases nastawu0119 aeration intensity value of one (10) if it is smaller nastawu0119 sludge age increases value of one (11).
