Abstract

PURPOSE: To effectively remove pollutants, etc. from filthy water with a simplified apparatus, by providing sand and pebble layers having thickness of 15W 25cm through a porous member at a space above the bottom in the water-running passage of a water-purifying cell, and growing aquatic plants in the water- running passage.
CONSTITUTION: Water to be purified is let flow into a water-running passage 5 where aquatic plants 4 are grown, to remove dissolved substance and organic substance such as nutritive salts of nitrogen, phosphorus, etc. in the water with the aquatic plants 4. The water to be purified is filtered by passing it through the layer of pebbles 7A and the layer of sand 7B in each of water-purifying cells 1AW1C and then brought into contact with air by letting the water fall downwards through the water-purifying cells 1AW1C having heads so that the water is affected by aeration. The thickness of the pebbles 7A is preferably at 15W 30cm, while that of the sand 7B is preferably at 15W25cm. The aquatic plants 4 in the water-running passage 5 are preferably grown in a manner such that the distance between their adjacent roots is held at 15W30cm.
