摘要： PROBLEM TO BE SOLVED: To prevent the water pollution caused by the propagation of microbes and algae economically and easily to handle without affecting the environment by floating glassy foam bodies in a layer state on the water surface of a water storage pond or the like, and shading the water surface with the layer of the glassy foam bodies. SOLUTION: Glassy foam bodies 2 are set afloat in a layer on the water surface 1a of a water storage pond 1, and the water surface is shaded by the layer of the glassy foam bodies 2. The layer of the glassy foam bodies 2 formed on the water surface shields the transmission of light, and the rise of water temperature is suppressed by the heat insulating effect of the glassy foam bodies 2. Generated algae are stuck to the surface of the glassy foam bodies 2 without being dispersed. If the glassy foam bodies 2 stuck with algae are landed at an appropriate time, the algae can be removed from the water surface. The pollution of water caused by the propagation of microbes and algae can be prevented economically and easily to handle without influence on the environment.
