A new approximate description of adsorption equilibrium of wastewater containing a number of unknown pollutants has been developed by using such a comprehensive index of concentration as TOC, BOD or COD. The description has been constructed on the basis of a new concept, "Characteristic Distribution of Langmuir Coefficient", which is to be identified by the observed differential adsorption equilibrium data. The accuracy of prediction of the integral adsorption equilibrium using this description has been demonstrated by several experiments.
