Zusammenfassung: | In regulating the aeration of a biological treatment of waste water, using (i) a step of aerobic elimination of carbon, (ii) a step of aerobic nitrification, and (iii) a denitrification step in absence of oxygen, the oxidn.-redn. potential in a treatment system is measured continuously, the curve of development of this potential as a function of time is established, and the deriv. is calculated. When this deriv. tends towards 0, the deriv. and the value of the potential are correlated, to decide on the start, the continuation or the ending of the aeration. |
