SEAWATER PERMEATION INTAKE APPARATUS
PROBLEM TO BE SOLVED: To promote the generation of a biofilm required for biofiltration, or the recovery of a biofilm that has sustained damage during operation.SOLUTION: The present invention relates to a seawater permeation intake apparatus 1 with which seawater that has permeated through a seabed filtration sand layer 2 and support gravel layer 3 is taken in by an intake pipe 4 that is buried in the support gravel layer 3. The apparatus includes liquid injecting means 5 for injecting a liquid containing microbes or a microbe growth-promoting agent into the filtration sand layer 2, in order to promote the generation of a biofilm required for biofiltration in the filtration sand layer 2, or the recovery of a biofilm that has sustained damage. On initial introduction, the time needed until the function of biofiltration is exerted is dramatically curtailed. If an external factor such as a rapid change in water quality causes damage to the biofilm during operation of the filtration sand layer, the biofilm can be recovered rapidly.
【課題】生物ろ過に必要な生物膜の生成、もしくは運転中に損傷を受けた生物膜の回復を促進する。【解決手段】海底のろ過砂層２及び支持砂利層３を浸透してきた海水を、支持砂利層３に埋設された取水管４により取水する海水浸透取水設備１である。ろ過砂層２における生物ろ過に必要な生物膜の生成、もしくは損傷を受けた生物膜の回復を促進するために、ろ過砂層２に微生物又は微生物の成長促進剤が含まれた液体を注入する液体注入手段５を備える。【効果】初期導入時、生物ろ過の機能が発揮されるまでの時間が従来よりも格段に短縮される。ろ過砂層の運転中に、水質の急激な変化などの外的要因により生物膜が損傷した場合も、早期に生物膜を回復することができる。【選択図】図１
