Abstract

This study developed an unmanned autonomous moving algae collection device (HAMA-bot) to remove high-density algae concentrated in the waterfront of urban agricultural reservoirs, and analyzed the effect of algae removal after field application to medium-sized urban reservoir. The algae reduction effect (Chl-a) of the study site in the reservoir by the HAMA-bot operation showed an average 18.5% higher in the treatment area compared to the control area before operation, while the average reduction of 24% in the treatment area after operation. In addition, the Chl-a removal rate, which directly analyzed the influent and effluent of HAMA-bot, showed a very high level with an average of 96.9% (94.7~99.2%). Currently, it is optimized for urban reservoirs and manufactured on a small scale, but it is a useful tool that can be applied on a large scale to large dams and rivers, and it is considered that the field applicability would be improved with the optimized scale.

본 연구는 도시형 농업용저수지의 수변부에 밀집되는 고밀도 조류를 제거하기 위해 무인자율이동 조류포집장치 (유해 조류 관리 자율 로봇, HAMA-bot)를 개발하였으며, 중규모 도시형 저수지에 현장 적용한 후 조류제거효과를 분석하였다. HAMA-bot 운영에 따른 Chl-a 농도는 처리구에서 평균 24% 감소되어 나타났다. 이는 일부 한정된 수역을 대상으로한 제한된 결과로 저수지 전체수역의 개선을 의미하지 않는다. HAMA-bot의 유입수와 유출수를 직접 분석한 Chl-a 제거율은 평균 96.9% (94.7~99.2%, 처리속도 60 m3 d-1 )로 매우 높은 수준을 보였다. 본 연구에서 개발된 HAMA-bot은 도시형 저수지에 최적화하여 적은 규모로 제작되었지만 대형댐호, 하천 등에 적용하기 위한 대규모화가 가능한 기술로 적정 규모로 현장 적용시 활용성이 높을 것으로 사료된다.
