The purpose of this study is to calculate the capacity of reclamation and reusing water in the housing site, and analyze the economic efficiency for public water reclamation and reusing system. The reclamation and reusing water was formulated by the function composed of the reclamation and reusing water coefficient(RRWC) and the size of housing site. The result of the economic assessment indicated that the proper facility size to secure the national and individual economic efficiency should be able to handle 4,000 tons/day and over (4,000 tons/day is applacable to the size of residential area of 1.2 million pyeong (=3.3㎡)), and for each usage, the business and commercial zones would have the best economic efficiency. And, the above-mentioned facility sizes were proved to be the optimal models by verification of maintaining the available river water quantity building up the ecological river in the housing site. Therefore, the application of the optimal models for the public water reclamation and reusing system, formulated in this study, has the important implication of securing water resources in response to a possible water policy, the ecological environment where humans and nature coexist, and a useful means to build up the water-friendly environment.

본 연구에서는 VOCs 물질을 효과적으로 제거할 수 있다고 알려진 코발트 프탈로시아닌 (Co-phthalocyanine)계 화합물을 합성하고, 휘발성유기화합물(VOCs)의 제거능을 고찰하였다. 극성이 높은 악취물질인 hydrogen sulfide, methyl mercaptane, dimethyl sulfide, dimethyl disulfide 등의 황화합물과 amina화합물의 경우 높은 제거율을 보였다. 황화합물의 경우 분자량이 큰 화합물일수록 흡착능이 좋았으며, triethylamine의 경우에는 유입유량이 500ml/min까지 좋은 흡착성능을 유지하였다.
