    • An object of the present invention is to provide a waste solution solidifying agent which can solidify a waste solution, particularly, a waste solution containing blood or body fluid at a low cost, uniformly, and in a short time; in particular, to provide a waste solution solidifying agent which can solidify a waste solution uniformly and in a short time in a vertically oriented waste solution equipment. As a means of achieving this object, a waste solution solidifying agent of the present invention is a particulate treating agent used in a method of treating a waste solution which solidifies a waste solution into a gel by placing a treating agent in a waste solution, and is characterized in that said agent contains, as an essential component, a water-absorbent resin having a crosslinked structure obtained by polymerizing a water-soluble ethylenic unsaturated monomer and, when flowing-placed at once into a 0.90 mass % aqueous sodium chloride solution, 20 to 95 mass % of the agent is floated, and 80 to 5 mass % is settled. And a process for preparing a waste solution solidifying agent of the present invention is a process for preparing a particulate waste solution solidifying agent containing, as an essential component, a water-absorbent resin having a crosslinked structure obtained by polymerizing a water-soluble ethylenic unsaturated monomer, and comprises a step of mixing a hydrophobic substance having a methanol index of 20 or more after polymerization.
    • 本发明的目的是提供一种可以以低成本,均匀和短时间固化废溶液,特别是含有血液或体液的废溶液的废溶液固化剂; 特别是提供一种能够在垂直取向的废液设备中均匀且短时间固化废液的废溶液固化剂。 作为实现该目的的手段,本发明的废溶液固化剂是将处理剂置于废液中而将废溶液固化成凝胶的废液的处理方法中使用的粒状处理剂, 其特征在于,所述试剂含有作为必要成分的具有通过使水溶性烯属不饱和单体聚合而得到的交联结构的吸水性树脂,并且当立即将其置于0.90质量%氯化钠水溶液中时, 漂白剂20〜95质量%,沉降80〜5质量%。 制备本发明的废溶液固化剂的方法是制备含有作为必需成分的具有交联结构的吸水性树脂的颗粒废溶液固化剂的方法,所述交联结构通过使水溶性烯属不饱和聚酯 单体,并且包括在聚合后混合甲醇指数为20以上的疏水性物质的工序。
