Abstract

PURPOSE: To obtain superior effect in solid-liquid separation of waste water contained organic matter by centrifugal separator, by using dicyandiamide-formaldehyde condensation type high molecular flocculant and chitosan group cationic high molecular flocculant for the waste liquid at the same time.
CONSTITUTION: Quantity of using chitosan group cationic high molecular flocculant is not limited especially, but, 10W70% of the above flocculant (but, the percentage is given be calculation based on the quantity of soled) is perferably used against the total amount of dicyandiamine-formaldehyde condensation type high molecular flocculant and chitosan group cationic high molecular flocculant from the viewpoint of good SS removal, permeability of treating liquid, COD and moisture content of cake. About 170W300 of mean molecular weight of dicyandiamine-formaldehyde type high molecular flocculant and more than about 4 of colloid equivalent value, are suitable for solid-liquid separation.
