<P>PROBLEM TO BE SOLVED: To improve the solid-liquid separation speed per unit area of a filter 21 in a solid-liquid separation drum 2 and to improve the collection rate of a solid part in a treatment object liquid W<SB POS="POST">1</SB>so as to improve clarity of a filtrate W<SB POS="POST">2</SB>. <P>SOLUTION: A precoating type solid-liquid separator includes: a treatment tank 1 for supplying the suspended treatment object liquid W<SB POS="POST">1</SB>; the filter 21 movably arranged to a fixed direction while being partly immersed in the treatment object liquid W<SB POS="POST">1</SB>in the treatment tank 1 and defining a filtrate storage chamber S in the treatment tank 1; and a collecting means 3 for peeling and collecting a precoating layer PC consisting of suspended particles adhering and accumulating on the outer peripheral face of the filter 21, and also includes large particle diameter suspended particle separating means 1E, 1F for separating large particle diameter suspended particles of relatively large particle diameters in the treatment object liquid W<SB POS="POST">1</SB>; and a large particle diameter suspended particle supplying means 4 for supplying separated large particle diameter suspended particles to the side in which the filter 21 non-formed with the precoating layer PC is immersed in the treatment object liquid W<SB POS="POST">1</SB>. <P>COPYRIGHT: (C)2012,JPO&INPIT |
