Description
本発明は、高速凝集沈澱池を立ち上げる際、水槽内において、初期原水と共に無機凝集剤及び凝集助剤を存在させて当該初期原水から初期母フロックを形成し、その後、当該初期母フロックの存在下で原水からフロックを形成する高速凝集沈澱法における初期母フロックの形成方法であって、微細砂からなる凝集助剤と、無機凝集剤とを、初期原水に加え、水槽内における微細砂の濃度を１００ｍｇ／Ｌ〜４０００ｍｇ／Ｌとして初期母フロックを形成することを特徴とする初期母フロックの形成方法を提案するものである。 In the present invention, when starting up a high-speed coagulation sedimentation basin, in the water tank, an inorganic flocculant and a coagulant auxiliary are present together with the initial raw water to form an initial mother floc from the initial raw water, and then the presence of the initial mother floc a method of forming an initial mother flocks in suspended solids method for forming a floc from the raw water under an aggregating aid composed of fine fine sand and an inorganic flocculant, in addition to the initial raw water, the fine sand in the water tank It proposes a method of forming the initial mother flocs and forming an initial base floc concentration as a 100mg / L~4000mg / L.
