Succession of benthos and nutrient removal rate in the hydroponic culture system; Shokubutsu suiko saibaikei ni okeru konken seibutsu no henka to eiyoen no jokyo

Abstract

Such nutrients as nitrogen and phosphorus discharged into lakes and rivers can cause organic contamination as a result of eutrophication in water areas if they are left as they are. However, they can be re-utilized as resources if they are utilized more effectively. This paper reports a hydroponic organism filtering method as a promising method of utilization thereof. It also explains transition in organism phase in rhizosphere and a water purification experiment. Such suspended matters as phytoplanktons in raw water are filtered and captured by roots of plants; such small animals as tendipedidae and physia live symbiotically in the rhizosphere; their excrements and nutrients are absorbed into and utilized by plants; and coexistence is made possible between diverse water-front environments including terrestrial systems and diverse living organisms. Cresson cultivation, observation on transition in the benthos composition, and a lake water purification experiment were carried out at the Kasumigaura Lake experimental facility. Various findings were acquired such that, in order to attain diverse coexistences including those with natural enemies and well-ventilated environments, a water channel of larger than a certain size is required. Results were also obtained that can be expected as an effective technique that may be used in public  More>>
