Slant Plates for Flocculation Formation and Flocculation Settling Treatment Tank Adopting the Slant Plates for Flocculation Formation

摘要

Slant plates for flocculation formation that efficiently form turbulent flow or vortical flows are installed in a settling treatment tank that performs a flocculation step including a step of further flocculating microfloc particles formed by an inorganic flocculant injection step and a micro flocculation step of micro-flocculating fine suspended particles by mixing and agitating in a rapid agitation tank; and a settling and separation treatment step for the floc particles; and an opening including an upper side edge and a lower side edge along a direction orthogonal to a direction of a slant surface is formed in each slant surface and a flocculation settling treatment tank in which the slant plates for flocculation formation are arranged at an uppermost portion or at a middle part.
