이상 상기에서 살펴본 바와 같이 본 발명은 비점오염원 유출수, 오염된 하천 및 마을 하수를 대상으로 하는 고효율 습지로서, 1차 침강, 2차 고효율 습지 및 3차 생태 여과를 통해 오염 물질의 농도 구배에 따라 최적 처리 시스템으로 구성된 것이다. 즉, 1차 생태 침강지(100)에서 입자성 오염물질을 효과적으로 제거함과 동시에 녹조발생을 억제하고, 2차 지표흐름습지(200)에서 식물과 토양 미생물에 의해 용존성 오염 물질을 제거하며, 3차 생태여과지(300)에서 미분해된 용존 오염물질과 재합성 탈리되는 미생물 플록(Floc) 등을 제거한다.As described above, the present invention is a high-efficiency wetland for non-point source runoff, polluted rivers, and village sewage, and is optimal according to the concentration gradient of pollutants through primary sedimentation, secondary high-efficiency wetlands, and tertiary ecological filtration. It consists of a processing system. That is, the primary ecological sedimentation area (100) effectively removes particulate contaminants and at the same time inhibits algal blooms, and the secondary surface flow wetlands (200) to remove dissolved pollutants by plants and soil microorganisms, 3 The primary ecological filter 300 removes undissolved dissolved contaminants and microbial flocs that are resynthesized.
따라서, 습지의 미생물 및 식물에 의한 생물학적 분해, 흡착침전여과 등의 물리화학적 처리를 극대화하여, 처리 효율을 안정적으로 유지하며, 처리 효율이 우수하다. Therefore, by maximizing the physicochemical treatment of biological degradation and adsorption precipitation filtration by microorganisms and plants in the wetlands, the treatment efficiency is stably maintained, and the treatment efficiency is excellent.
또한, 처리 속도가 빨라 체류시간을 줄이고, 이에 따라 필요 소요 부지를 적게 하므로서, 경제적 비용절감 효과를 이룩하여, 자연친화적 수처리 기술 보급을 통한 수질환경 개선에 이바지할 수 있는 효과를 발휘한다.In addition, the treatment speed is faster, the residence time is shortened, and thus the required site is reduced, thereby achieving an economic cost reduction effect and contributing to the improvement of the water environment through the diffusion of nature-friendly water treatment technology.
한편, 본 발명은 처리시설 상부가 전체적으로 아름다운 식물로 구성되므로, 생태 공원, 자연학습장 등으로 활용 될 수 있으며, 식물 군락은 저서생물, 곤충, 양서류, 파충류, 생들의 서식처를 제공함으로서 생태 복원의 기능까지 수행할 수 있는 장점을 발휘한다.On the other hand, the present invention can be utilized as an ecological park, a nature learning center, etc., because the upper part of the treatment facility is composed of beautiful plants as a whole, the plant community provides a habitat for benthic creatures, insects, amphibians, reptiles, life, etc. Demonstrate the advantages that can be performed up to.
