대구시 S하수처리장 운전실태 분석을 통한 하수처리수 재이용 확대 방안 연구

Providing against shortage of water resources, we have to recognize importance of treated sewage and increase its using. Until now, the rate of reusing is 2.9% which was involved in 2000. Rate of treated sewage is high and water Quality at the sewage is being improved by advanced water treatment in Daegu, but the highest rate of reusing in Daegu is about 11% in S-sewage disposal plant. In this study, after analyzing the actual state of operation of S-sewage disposal plant which has the highest rate of reusing in Daegu for diversifying reuse and activating of spread, problems and better plans are earned out researches. As results that are the analyzed energy consumption, water Quality and operation costs of S-sewage disposal plant, spread of use is possible in the water Quality aspect, but it is necessary to study closely adequacy later on.
