Abstract: At this point in time when the world is suffering from global warming, pollution of rivers and oceans due to water shortage and industrialization is deepening. The reality of Korea is that as the four main rivers are suffering from green algae and eroded pollutants, environmental groups and the government are insisting on dismantling the weirs, and the farmers are fighting against the dismantling of the weirs. The rise of the current temperature in May is at a level of the summer, and abnormal temperatures due to global warming cause the pollution of the rivers and oceans to become more serious. The present invention is not only for the invention of the Republic of Korea, and it is hoped that the present invention can contribute to global climate change. A fundamental technology for collecting green algae and oil uses the principle of floating on water, and decayed sediment and soil pollutants in the water rise to the surface of the water by the buoyancy of sprayed air, and are suctioned and collected together with green algae. The green algae can be minimized by preceding work on shores adjacent to the oceans or the rivers and the shores of coastal fisheries where a large amount of urban wastewater is discharged. It is believed that only the steady work of a collecting vessel can sufficiently improve the soil quality in the water. It is a great tragedy to dismantle the weirs of the four main rivers that had wasted 25 trillions of the precious money of tax payers, and the only way to save the weirs is to remove the green algae. Even if collecting vessels are distributed throughout the Korean rivers and oceans, it is expected that the rivers and the sea can be saved at low cost. The present invention has been devised since the oil spill accident in Taean, and it is hoped that this invention, which has been applied for after long years, will not be buried and can contribute to the national interest. A separation tank can separate green algae or oil from water.
