MOBILE TYPE SUSPENDED MATTER COLLECTION DEVICE IN INFILTRATION SEAWATER INTAKE

PROBLEM TO BE SOLVED: To efficiently and speedily collect suspended matters belched into seawater when cleaning a filter layer.SOLUTION: A mobile type suspended matter collection device 11 comprises: suction means 21 which belches air or seawater into a filter layer 52 through a cleaning pipe 57 and sucks and collects turbid water containing suspended matters belched into an upper water area S1 above the filter layer 52 when cleaning the filter layer 52; and transfer means 31 which enables the suction means 21 to transfer to a predetermined position in a water intake area with the same suspended in the upper water area S1 above the filter layer 52. The mobile type suspended matter collection device 11 enables the filter layer to be installed in a sea area having little seawater flux due to tides and waves. The mobile type suspended matter collection device 11 also can reliably prevent clogging of the filter layer even with a high seawater infiltration speed and maintain the high seawater infiltration speed. 【課題】ろ過層の洗浄時に海中に噴き上げられた懸濁物質を効率良く、速やかに回収する。【解決手段】洗浄管５７からろ過層内５２にエアー又は海水を噴出し、ろ過層５２を洗浄したときにろ過層５２の上方水域Ｓ１に噴き上げられた懸濁物質を含む濁水を吸引して回収する吸引手段２１と、この吸引手段２１をろ過層５２の上方水域Ｓ１に吊設した状態で、取水エリア内の所要の位置に移動可能とする移動手段３１とを備えた移動式懸濁物質回収装置１１である。【効果】潮流や波浪による海水流動が少ない海域であってもろ過層を設置できるようになる。海水の浸透速度を高速にした場合でも、ろ過層の目詰まりを確実に防止し、高速の浸透速度を維持できる。【選択図】図１
