摘　　要：对模拟含硼废液制粉及盐粉造粒技术进行了研究,包括废液制粉、盐粉直接造粒、废液加氢氧化钙预处理、预处理后废液的制粉和盐粉造粒以及废液与氢氧化钙反应的条件试验等。结果表明,原始盐粉可以成功造粒,但其抗浸泡性能不满足要求。在条件试验推荐的工艺操作参数下(Ca/B摩尔比0.50,反应温度75℃,反应时间60 min),加氢氧化钙预处理后的废液仍然可以制粉,且制得的盐粉造粒后,粉粒的抗水浸泡性能能满足后续固化要求。Experiments involving liquid-waste powdering, direct granulation from powdered salts as well as the performance of calcium hydroxide formula was carried out to investigate the treatment technology of simulated boron-containing liquid waste. The results indicate that powdered salts can be made into pellets, but their water immersion performance can not meet the requirement. At the parameters （Ca/B molar ratio is 0. 5, reacting temperature is 75℃ , and reacting time is 60 rain） being recommended after test, waste liquid can be successfully powdered after pretreatment by adding calcium hydroxide, and water immersion resistance of pellets meet the requirement of solidification after the powdered salts being made into pellets.
