The transfer processes of organic pollutants during sewage - seawater mixing were simulated in three different mixing systems. The release rate of organic matter from sewage particles to seawater was found to be about 0.02-0.04d-1 . The release processes can be simulated by an exchange-equilibrium kinetic model. Degradation of COD was observed in all three mixing systems and can be described by a first order kinetic equation. The degradation rate constant k ranged between 0.04 and 0.07 d . These results have provided important parameters for estimation of environmental capacity.
