초록
본 연구의 최종 목표는 실내의 공간과 식물바이오필터의 규모에 따라 실내공기 오염물질을 정화할 수 있는 식물 녹화와 자동관수 그리고 생물학적 여과 기능을 통합한 식물바이오필터시스템의 개발이다. 본 실험에 사용된 식물 바이오 필터는 실내공간을 효율적으로 사용하기 위해 물펌프, 물탱크, 송풍기, 가습장치, 그리고 다층 구조의 식물 식재 공간을 일체형으로 설계하였다. 본 연구는 인공적인 실내 공기 오염원을 발생시키지 않은 상태에서 바이오필터 부근의 공간과 바이오필터와 멀리 떨어진 공간(무처리구)의 실내 공기질을 비교하고, 바이오필터 내다층 구조의 식재층에 따른 식물의 생육을 평가하고자 수행하였다. 바이오필터 처리 공간 내 휘발성 유기 화합물(TVOCs),일산화탄소, 이산화탄소와 같은 실내 공기 오염물질의 농도는 무처리구에 비해 낮게 나타났다. 또한 바이오필터 내 식재된 층에관계없이 Dracaena sanderiana ‘Vitoria’와 Epipremnum aureum ‘N Joy’는 정상적으로 생육하였다. 따라서 실내식물을 식재할수 있는 본 벽면형 식물바이오필터는 실내 공기 정화에도 효과가 있는 것으로 확인하였다.
Abstract
The final goal of this research is to develop a botanical biofiltration system, which combines green interior, biofiltering, and automatic irrigation, which can purify indoor air pollutants according to indoor space and the size of biofilter. The biofilter used in this experiment was designed as an integral form of water metering pump, water tank, blower, humidifier, and multi-level planting space in order to be more suitable for indoor space utilization. This study was performed to compare indoor air quality between the space adjacent to a botanical biofilter and the space away from the biofilter (control) without generation of artificial indoor air pollutants, and to evaluate plant growth depending on multiple floors within the biofilter. Each concentration of indoor air pollutants such as TVOCs, monoxide, and dioxide in the space treated with the biofilter was lower than that of control. Dracaena sanderiana ‘Vitoria’ and Epipremnum aureum ‘N Joy’ also showed normal growth responses regardless of multiple floors within the biofilter. Hence, it was confirmed that the wall-typed botanical biofilter suitable for indoor plants was effective for indoor air purification.
