| Research Abstract |
In the cistern for agriculture which eutrophication is following by flying of the migratory bird, processing of sediment in which the nutrition salt of feces-and-urine origin was accumulated poses an important problem. On the other hand, if this sediment is utilizable as agricultural fertilizer or a substrate of methane fermentation, it will lead to sediment processing or cost mitigation of agricultural output activities. About the two above-mentioned points was conducted, the laboratory experiment which uses sediment of the Oyama-Kamiike pond and Shimoike pond at Tsuruoka-city, Yamagata. As a result, by mixing sediment about 7% by weight conversion showed that an effect almost equivalent to a habitual chemical fertilizer was acquired. Moreover, in methane fermentation, the result that about 30% of methane was callable was obtained at the maximum by adjusting temperature environment.
