Abstract

|
Eutrophication was known as the existence of a increasing mineral ingredients in the late and stream, which fallen leaves and organic matters were accumulated in many year ago resulting: the life cycle of plankton and inferor animal. But according to the development of industry and mordernization of human life, industrial wastes and sewages are containing very high concentration, of the phosphate and nitrate compare with decades before, leaving cultural eutrophication which is one of the nuissance in human activity. The phenomenon of the prosperously growing algae in the sea and river` are a: great trouble making problem in getting- potable water, industry, fishery etc. We know the actual ingredients making cultural eutrophication are carbon, nitrogen and phosphorous, but we can- only control -thin phenomenon by removing phosphate attached on- the alkyl benzene sulfonate (ABS): which is:, used as a detergents. The author attempted to make know the status of the cultural eutrophication in Korea and .studied the phosphate removal rate by various absorbents. As the result. following conclusions were appeared clearly:
1. The concentration of the phosphate in river and sea water was ranged from 0.Oippm to- 0.-13ppm of which values indicate that there could be exist the cultural, eutrophication.
2. A12(SO,)Z was best absorbent in th phosphate removal test,
3. In the experiment of ABS remove active, carbon with 500 ppm eliminated 99% of, ABS
4. For the purpose of the eutrophication elimination artificial detergents should be completely removed
