1. Purify water quality and degrade COD, nitrogen and phosphorus in water.
is mainly for the eutrophication of water quality, by reducing the concentration of COD (chemical oxygen demand), nitrogen, and phosphorus to suppress the occurrence of red tides and improve the perspective of water.
Water purification elements include:
1) The adsorption of organisms, especially algae, on the surface of plant stems;
2) Nutrient absorption of plants;
3) Feeding and emergence of aquatic insects;
4) Bait and predation of fish;
5) Prevent the suspended substance that has settled from floating again;
6) The shading effect of sunlight;
7) Nitrogen removal on the surface of lake mud.
2. Create a living environment for creatures (fish\birds).
itself has proper sheltering, eddy current, feed and other effects, constituting good conditions for fish to live. A survey of Lake Biwa in Shiga Prefecture revealed that 85 million carp and other three fish eggs were found in a water area of approximately 1,500 m2 composed of 60 artificial floating islands. In order to strengthen the function of artificial floating islands as fish spawning beds, some ropes are tied under the floating islands to improve the structure of the floating spawning beds for carp and other fish.
