| As the aeration is one of the most important roles for the purification of polluted water, aquatic aerobic microorganism makes use of aerated dissolved oxygen to decompose the pollutant and purify water. In this study, a reactor was operated in a laboratory to examine the effects of salinity and rainfall on reaeration and then a model was proposed to estimate the reaeration coefficient. From the results of the experiments, the reaeration coefficient, $k_2$($day^{-1}$), can be expressed by $k_2=k_{2f}+3.98667{ imes}10^{-2}{cdot}C+4.88437{ imes}10^{-1}{cdot}r;where;k_{2f}$ : the reaeration coefficient in the fresh water at $20{circ}C,;(day^{-1})$ C: chloride concentration, ($g/{ell}$), r:rainfall intensity,(mm/hr) Accordingly, it is concluded that the rate of reaeration is proportional to the chloride concentration and rainfall intensity. Also, it is known that the rainfall intensity contributes to the overall oxygen balance in a body of water more significantly than the salinity. |
