For the characterization of advanced wastewater treatment process, it is not enough to express the water quality as BOD or COD which is the overall index of organic pollution. The treatability of organic wastewater has been characterized by the, molecular weight distribution and organic analysis. We here tried to introduce hydrophile-hydrophobic properties of organicfor evaluation of biodegradability and activated carbon adsorbability.
The biodegradability and activated carbon adsorbability were tested on 64 compounds based on BOD analysis and adsorption isotherm respectively. The relation to the hydrophile-hydrophobic ratio of organics which were determined by organic conceptional diagram developed by Fugita was investigated.
It was observed that the hydrophilic properties tended to promote the activated carbon adsorbability and the hydrohile properties tended to promote the biodegradability with some exceptions. Some informations on treatability were obtained when the organics were classified on the hydrophile-hydrophobic properties which corresponded to the ratio of biodegradability to activated carbon adsorbability.
