| Abstract |
For the study of phosphorus influencing in water quality, TP and PO₄-P were surveyed a time a month at 18 points of Jungrang stream and downstream in Han river tributary and Jinwi stream in Ansung stream tributary. To study phosphorus improvement in stream resulted from supplying phosphate free detergent on July, 1988 in Korea, 3 points of agriculture, urban, complex area near Jungrang stream were selected and the flowing rates of ABS, phosphorus each point were surveyed for a whole day of April, 1988, supplying phosphate synthetic detergent and August, November, 1988. Supplying phosphate free detergent. By the results, we can know that inflow of phosphorus into stream was caused by other pollutant sources than phosphate detergent, and water quality in stream has been improved by considerable decreasing of phosphorus concentration in domestic wastewater resulted from supplying of phosphate free detergent. |
