Abstract
A method of treating a liquid borate waste includes the following steps: modulating a raw liquid borate waste; concentrating the liquid borate waste to make a high-concentration liquid polyborate waste; performing granulation of the high-concentration liquid polyborate waste with a granulating agent and preparing solid borate granules; and making the solid borate granules into a monolithic waste form with good performance.
Claims9
A method of treating a liquid sodium borate waste to produce a monolithic solid with high strength and high water immersion resistance, comprising:
- making a raw liquid borate waste into a liquid waste containing polymerized sodium borate with high polymerization degree;
- reacting the liquid waste containing polymerized sodium borate with high polymerization degree with a granulating agent and preparing a plurality of borate granules;
- and
- preparing a solidified waste form of borate granule and an immobilized waste form of borate granule compressed block respectively by either (1) or (2);
- (1) mixing the plurality of borate granules and a hardenable slurry to form a hardenable granule slurry, and curing the hardenable granule slurry to form a solidified waste form of borate granule;
- and
- (2) compressing the borate granules into a compressed block, pouring a hardenable slurry to clad the compressed block, and curing the hardenable slurry to form an immobilized waste form of borate granule compressed block(s).
