The present invention relates to an environment-friendly dredger and, more specifically, to an environment-friendly dredger which increases the dissolved oxygen by injecting nanobubbles having negative ions when sludge accumulated on the bottom of water is diffused underwater and contaminates the water during a process of excavating sand or rock on the bottom of water in a small stream, a river, a port, etc. to make the depth of water deep or to obtain construction materials using a dredging machine installed in the dredger, thereby controlling and removing anaerobe bacteria. Moreover, the present invention activates and increases aerobic bacteria, and removes contaminants and heavy metals by coupling the negative ions to the contaminants having positive ions. The environment-friendly dredger comprises: a nanobubble generating device; an angle control device which has a bracket, a tilting means, and a fan drive means; an input device which sets manual and automatic modes; and a control device which outputs a control signal.

    본 발명은 친환경 준설선에 관한 것으로, 더욱 상세하게는 준설선에 설치된 준설기를 이용하여 물의 깊이를 깊게 하거나 건설 재료를 얻기 위하여 개울이나 하천, 항만 등의 물밑바닥에 쌓인 모래나 암석을 파내는 과정에서 물밑바닥에 쌓인 오니가 수중으로 확산되면서 수질이 오염되는데, 이때, 나노 버블(마이너스 이온을 띰)을 분사하여 용존산소량을 증가시켜 혐기성 세균의 증식을 억제시킴과 동시에 소멸시키고, 호기성 세균을 활성화함과 동시에 증가시키며, 마이너스 이온이 플러스이온 상태인 오염물과 결합해 오염물과 중금속을 제거하도록 된 친환경 준설선에 관한 것이다.
