Title:

WASTE SOLUTION TREATMENT TANK AND WASTE SOLUTION TREATMENT METHOD FOR SODIUM ALUMINATE-CONTAINING WASTE SOLUTION

Document Type and Number:

Japanese Patent JP2016000384

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a waste solution treatment tank for a sodium aluminate-containing waste solution where, in a single tank-integrated type waste solution treatment tank used for the surface treatment of an aluminum material and the treatment of a sodium aluminate-containing waste solution exhausted in the process of molding, particularly, the generation amount of the clinker of aluminum hydroxide to the inner wall part of a separation part is reduced as possible to prevent the problem caused by clinker sticking, and a waste solution treatment method for sodium aluminate-containing waste solution where, using the same, the sodium aluminate-containing waste solution is treated, and a sodium hydroxide solution and aluminum hydroxide are separated.SOLUTION: Provided is a waste water treatment tank for a sodium aluminate-containing solution being a single tank-integrated type in which a precipitation part and a separation part are integrally composed, characterized in that the precipitation part located at the lower part of the tank body is provided with a cooling means, and further, the separation part located at the upper part of the tank body is provided with a heating means.
