Abstract

In order to plan out the Daegu G membrane filtration water treatment plant, water quantity, water quality and process stability were evaluated using the field pilot-scale tests, during the six months of continuous operation, including low water temperature period. The field model experiments, which were carried out according to the Installation Criteria of Ministry of Environment, consisted of two series : series 1 - water quality verification, and series 2 - membrane process evaluation. The process water quality met all drinking water standards with less than 0.03 NTU. Moreover, process operation showed a stable membrane pressure with 99% of recovery ratio. This shows that the tests were properly designed in terms of the influence of water loading and temperature. In conclusion, the purpose of this study is to establish core technology for advanced drinking water treatment, through on-going accumulation of engineering and construction know-how.

본 연구에서는 대구 G정수장 막여과 정수처리시설을 계획하기 위해 원수수질 처리에 적합하고 경제적인 시스템을 적용하고자 현장모형실험을 통하여 동절기를 포함한 6개월 동안의 연속운전에 따른 수량과 수질, 그리고 공정의 안정성을 평가하였다. 환경부 막여과 정수시설의 설치기준에 의해 실시된 현장모형실험에서 1계열 목표수질 검증설비와 2계열 막공정 평가설비로 나누어 2계열로 수행되었다. 공정수질은 탁도 0.03 NTU 이하로서, 증류수 수질의 탁도를 나타내었으며 먹는 물 수질기준을 모두 충족하였다. 공정운전에서 99%의 회수율로 안정된 막차압을 나타내어 공정운전에 수질 및 수온 등의 영향에 대비한 공정설계가 되었음을 확인하였다. 따라서 지속적인 기술개발을 통해 설계 및 시공 노하우에 대한 지속적인 경험이 축적되어 막여과 고도정수처리 기술에 대한 엔지니어링 원천기술을 확립하고자 한다.
