摘要： Implementations herein relate to methods for reducing a desorption solution for regeneration of ion exchange resins in the field of regeneration of resins. The implementations solve problems related to low utilization rates of regeneration agents and high volumes of desorption solutions during the desorption process. The implementations include regenerating the ion exchange resins, and the regeneration solution becomes the desorption solution. After coagulating sedimentation of the desorption solution and slurry separation, a large amount of organic contents are removed from coagulation serum and a large amount of regenerate agents are left. The implementations further include adding the regeneration agent to the coagulation serum to form new or refreshed regeneration solution to regenerate the ion exchange resins. Accordingly, the coagulation serum may be generated from the desorption solution. These operations may be repeated multiple batches for resin regeneration.

摘要翻译： 本文的实施方案涉及在树脂再生领域中减少用于离子交换树脂再生的解吸溶液的方法。 这些实施方案解决了在解吸过程中与再生剂的低利用率和大量解吸溶液相关的问题。 这些实施方案包括再生离子交换树脂，并且再生溶液变成解吸溶液。 在解吸溶液凝结沉淀和浆液分离后，从凝血液中除去大量的有机物，并留下大量的再生剂。 实施方案还包括将再生剂添加到凝血血清中以形成新的或更新的再生溶液以再生离子交换树脂。 因此，可以从解吸溶液产生凝血血清。 这些操作可以重复多次用于树脂再生。
