Receiving to the culture method of itogokai for organic matter sludge purification, and the purification methodological null

摘要

PROBLEM TO BE SOLVED: To provide a method for more efficiently cleaning an organic substance sludge by preculturing a large amount of Capitella sp.1 as benthos and positively scattering the cultured Capitella sp.1 on the organic substance sludge in the autumn when this organism can live. SOLUTION: The method for culturing Capittela sp.1 for cleaning an organic substance sludge is characterized in that a feed is periodically scattered on a Capitella sp.1 culture substrate and Capitella sp.1 stored in a seawater tank, and Capitella sp.1 is cultured at 5-25 deg.C with aeration until Capitella sp.1 density reaches 4×106 organisms/m2. The method for cleaning an organic substance sludge is characterized in that the culture substrate containing Capitella sp.1 in high density obtained by the culturing method is scattered on a deposited sludge in a target sea area to be cleaned and the organic substance sludge is cleaned by utilizing the organic substance consumption force of Capitella sp.1.
