PROBLEM TO BE SOLVED: To provide a waste liquid treatment method capable of being employed for a nuclear power plant, wherein treated water having a high purity can be obtain economically by using a cation resin with a high degree of crosslinking, and provide a waste liquid treatment apparatus. SOLUTION: In the waste liquid treatment method for cleaning waste liquid, the waste liquid is made to pass through a mixed bed consisting of a strong acid gel cation resin having a degree of crosslinking of 12-16% and a strong basic anion resin for cleaning, and one or both of the cation resin and the anion resin have a uniform particle size distribution. Preferably, the cation resin has a degree of crosslinking of 14%, and the waste liquid may be filtered before being made to pass through the mixed bed of the ion exchange resins. The waste liquid may be filtered by employing a hollow fiber membrane filter, a precoat filter device or a pleat filter. COPYRIGHT: (C)2004,JPO
