영문 초록

  Eutrophication derived from the excess inflow of organics and nutrients into discharge basins results in the mass production of algae, causing other secondary water pollution. Also, toxic alg- ae have been associated with eutrophication in coastal regions and have been implicated in the occrrernce of "red tide" which may lead to paralytic shellfish poisoning. But existing methods that are weak in the performance of from 10 to 20 percent N, P removals have not coped with the water pollution owing to eutrophication. In this study, to research treatment characteristics of media in conventional activated sludge system, existng Conventional Activated Sludge system and Media-introduced Activated Sludge system are made a comparative study using a pilot plant in the field. In the performance of Organic matter removal, Media-introduced methid is better than non Media method, improving BOD average removal 5%, COD 18%, respectively and in nutrients T-N 27% and T-P 12.3%, average. Experiments have it that Media-including methods with shorten HRTs(5 hours) is more satisfactory than Conventional Activated Sludge system with 7 hours.
