Abstract
Using experimental microecosystems the kinetics of phenol disappearanc e in river and reservoir water were investigated. In river water the d isappearance kinetics could be described by A first-order equation, th e same kinetics took place in reservoir water before and after the per iod of ''bloom'' of blue-green algae. During the ''bloom'', the phenol seemed to be mineralized by bacteria which grew at the expense of ano ther compound, and the model of best fit was the model of exponential growth and low concentration of the test substrate. In the river, two sections differed according to the difference between the mean values of the specific disappearance rates. In the reservoir these rates were lower than those in the river. In general the specific disappearance rate values did not correlate with the values of initial bacterioplank ton density, the concentrations of inorganic nutrients nor the chemica l oxygen demand. Conclusions about the integral influence of ecosystem s on the disappearance rates and dependence of self-purification kinet ics on the type of aquatic ecosystem were made.
