WATER MICROBIAL CARRIER MATERIAL AS WELL AS WATER MICROBIAL INDUCED PROLIFERATION METHOD USING THE SAME AND WATER AREA FERTILIZATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a water microbial carrier material and a water microbial induced proliferation method in which a water purification effect can be maintained over a long term in a closed water system and an open water system, can be executed at low cost and the utilization of bamboo is made possible.SOLUTION: A water microbial carrier material is formed such that cotton-shaped green bamboo fibers obtained by compressing and pulverizing the green bamboo culm so as to cleave the cell walls of fibrous cells are filled in the inside of a bag body and sealed. This water microbial carrier material is submerged underwater. The water microorganisms enter the cleaved fiber cell walls are fixed and propagated to form an ecosystem in this. By this ecosystem, the underwater organic matter is decomposed efficiently, and underwater eutrophication is suppressed to promote water purification. The bamboo fibers take around several years to corrosion/disappearance, and therefore the microorganism carrier can be maintained for several years without disappearance. Also, the nitrogen fixing bacteria generated in the cell walls are brought into nitrogen fixation in a natural environment water area, and the propagation of aquatic plants is promoted. The propagated aquatic plants take underwater phosphate ions therein, and the underwater eutrophication is suppressed.SELECTED DRAWING: Figure 1
