The object and purpose of this study was to determine the total biological oxygen consumption (BOD) of the formation waters of the oil fields of the Absheron Peninsula of the Azerbaijan Republic and also finding out the rate of decomposition of components in water of petroleum origin. The biological oxygen consumption (BOD-total) in the sample was determined using the method of measuring the dissolved cell for a certain period of time. Also, for the accuracy of the measurements, an analysis of chemical oxygen consumption (COD) was carried out, which is equal to the total biological oxygen consumption. It was found that within 90 days more than 98% of the organic substances contained in the reservoir waters of the Absheron Peninsula, completely decompose and when discharged in diluted form does not adversely affect the environment.

RESEARCH OF THE ULTIMATE BIOLOGICAL OXYGEN DEMAND IN THE PRODUCE WATER OF OIL DEPOSITS IN THE ABSHERON PENINSULA OF AZERBAIJAN REPUBLIC.
