PROBLEM TO BE SOLVED: To provide a method for minimizing the amount of used flocculant and performing clarification in turbid water over a long period of time.SOLUTION: In a treatment method in flowing turbid water, slime forming bodies 8 are extended against a water flow, and a flocculant having viscosity when brought into contact with water and/or at least one organism selected from spiral and curved bacteria, ciliates, rhizopoda, and diatoms are added to the front surface of the slime forming bodies to treat the turbid water.SELECTED DRAWING: Figure 1
【課題】凝集剤の使用量を可及的に少なくし、かつ長期に亙り濁水中の清澄化を行う方法を提供する。【解決手段】流れのある濁水中の処理方法において、スライム形成体８を水流に対して対抗するように展張し、スライム形成体の前面に、水に接したときに粘性を有する凝集剤および／または螺旋菌類、繊毛虫類、根足虫類、珪藻類から選ばれた少なくとも１種の生物類を添加して処理する濁水の処理方法。【選択図】図１
