하수처리장 처리수의 工業用水 재이용시 經濟性 評價에 관한 硏究

To provide against shortage of water resources, the importance of treated sewage is recognized and its using is increased, and yet the rate of reusing it is 2.9% in 2000. Rate of treated sewage is high and the quality of water in the sewage is being improved by advanced water treatment in Daegu, but the rate of reusing wastewater treatment in Daegu is low, and that in S-sewage disposal plant which has the highest rate of reusing it in Daegu is about 11%. As compared with the amount of water supplied(in 2001) of a local autonomous entity, the rate of using domestic water as industrial water in Daegu reaches the highest level at 441l. In this study, after the actual state of operation of S-sewage disposal plant is analyzed, economic evaluation is estimated when wastewater of S-sewage disposal plant is reused as industrial water in the Third industrial complex. This research is anticipated to be fundamental data for diversifying reuse.
