To stabilize the removal efficiency of suspended matter by enabling treatment capacity to be increased or decreased according to the amount of the suspended matter in turbid water while minimizing an influence on the environment.SOLUTION: A turbid water treatment system includes an accordion type filtration device 5 which partitions a treatment water tank 2 into a plurality of sections, and in which a plurality of panels 4 each including a filter 3 are connected so as to be foldable in an accordion shape. When the measured value of a suspended matter amount measuring device 6 is equal to or lower than a prescribed value, a control device 7 controls part of the panels 4 in the accordion type filtration device 5 in a state of being arranged in an unfolded state where the panels adjacent to each other form the same plane. When the measured value of the suspended matter amount measuring device 6 becomes higher than the prescribed value, the control device 7 controls all of the panels 4 in the accordion type filtration device 5 in a state of being folded in a zigzag shape where substantially triangular mountain-folded parts and valley-folded parts are alternately repeatedly formed, without making the adjacent panels face each other.SELECTED DRAWING: Figure 1 【課題】環境に与える影響を最小限に抑え、濁水の浮遊物質量に応じて処理能力が増減できるようにすることにより浮遊物質の除去効率を安定化させる。【解決手段】処理水槽２を複数の区画に仕切るとともに、フィルタ３を備えた複数のパネル４がアコーディオン形状に折り畳み可能に連結されたアコーディオン式ろ過装置５を備える。制御装置７は、浮遊物質量測定器６の測定値が所定の値以下の場合、アコーディオン式ろ過装置５の一部のパネル４が、隣り合うパネル同士で同一の平面を形成する展開状態で配置された状態に制御し、浮遊物質量測定器６の測定値が所定の値より高くなった場合、アコーディオン式ろ過装置５の全てのパネル４が、隣り合うパネル同士を対面させることなく、略三角形状の山折り部と谷折り部が交互に繰り返し形成されるジグザグ状に折り畳まれた状態に制御する。【選択図】図１
