Title:
METHOD FOR REMOVING SUSPENDED SUBSTANCES WITHIN AN EFFLUENT
Document Type and Number:
Japanese Patent JP2014133229
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide, by targeting a method for separating and removing, from an effluent including crude suspended substances (SS), the SS, a method for removing SS within an effluent extremely useful from an industrial standpoint and capable of yielding treated water of a favorable quality very quickly, of reducing the addition ratio of a flocculant, of significantly simplifying facilities, of reducing facility costs and maintenance and management costs, of reducing the cost of recycling a generated precipitate, and of avoiding problems attributed to inorganic flocculants.SOLUTION: The provided method for removing suspended substances within an effluent is a method for removing suspended substances within an effluent conceived for flocculating, precipitating, and removing suspended substances from an effluent by using a flocculant in which at least one type of organic flocculant is used as the flocculant and a state where at least crude suspended substances and fine suspended substances coexist in the co-presence of the organic flocculant within a body of turbulent water having a flow velocity of at least 0.5 m/sec is induced to arise so as to enable the flocculation and precipitation of the crude suspended substances and fine suspended substances in the course of an identical treatment and simultaneous removals of both.
