Abstract

PURPOSE: To positively purify the contaminated water of lakes and marshes, closed system sea area etc., by introducing the water into a special purification apparatus provided floating on said area and purifying by soil aerating in the apparatus.
CONSTITUTION: Purification apparatus of contaminated water composed of the pebble layer 10, the soil layer 9, the aeration apparatus and the bottom opening 5, etc. through the outer wall 1, the bottom wall 4 and the nonwoven fabric 11 made of the material, such as vinyl chloride, having a low specific gravity, is provided floating on lakes and marshes, closed system sea area etc. Falling of the soil 9 in the layer 10 is prevented by the fabric 11 and also, air, water, microorganism, are passed through said fabric. Said apparatus is inexpensive compared with the usual apparatus and the contaminated water of the lakes and marshes, closed system sea area, treating pond etc., is positively purified and also, treating capacity of the treating pond is heightened by providing on already constructed pond.
