VEGETATION PLANTING TYPE GROIN BLOCK

摘要

PROBLEM TO BE SOLVED: To solve such a problem that water can not be deenergized due to an unstable state companied by a resistance of the flowing water force in the block body and the river water can not be purified. SOLUTION: The block 1 is constituted of a bag having an appropriate width and height, made of water-permeable carbon-based fiber or the like and formed in a triangular section and adsorptive zeolite granules 4 mixed with seeds of water plants having nitrogen-retentive and phosphorus-retentive force contained in the bag. The blocks 1 are connected to each other and arranged in accordance with the river and the flow rate to control water, germinate and grow water plants, remove nitrogen and phosphorus, purify ammonia and other pollutions in the river water by the adsorptive force of the zeolite.
