Description

Eco-friendly apparatus for collecting marine sediments The present invention relates to an eco-friendly marine sediment collection device. More specifically, it relates to an eco-friendly marine sediment collection device capable of preventing the spread of airborne pollutants that may occur during marine sediment collection and collecting and purifying them in real time. Recently, the amount of various waste materials flowing from land into the sea, as well as fisheries-related waste, settling or floating near the coast has been increasing, leading to serious destruction of the coastal ecosystem. To solve these problems, marine sediment collection devices have been designed and are being used in various ways, such as scooping up or sucking up sediment using devices that are elongated to reach the ocean floor. Recently, technologies for efficiently removing sediments deposited on the seabed are being actively developed. Generally, marine sediments contain various pollutants such as organic matter, fine particles, heavy metals, and petroleum-based pollutants, and these sediments tend to accumulate particularly prominently in areas such as ports, river inflows, and sewage discharge points. To collect these sediments, devices that directly suck up seafloor sediment using a suction pipe and transport it via a pump are widely utilized. However, the process of forcibly sucking up or disturbing the sediments causes adverse effects, such as large quantities of suspended particles and pollutants being dispersed into the seawater and spreading to nearby waters. In particular, since airborne pollutants dispersed by the flowing seawater during collection spread immediately, they can lead to water quality deterioration and damage to marine life without separate control measures. Currently, intensive technological development is being conducted on collection devices for marine sediments, but there is almost no technological development regarding the blocking and prevention of diffusion of suspended pollutants generated during the collection process. Consequently, this leads to problems such as the induction of new marine pollution.
