Boron-containing waste liquid cement curing formula and curing method
The present invention particularly relates to a boron-containing waste liquid cement curing formula and a curing method, the boron-containing waste liquid cement curing formula comprises ordinary Portland cement, slaked lime, an additive, a molecular sieve, a concentrated waste liquid and calcium chloride, and the weight ratio of the ordinary Portland cement to the slaked lime to the additive to the molecular sieve to the concentrated waste liquid to the calcium chloride is 1: 0.174-0.194: 0.008-0.012: 0.02: 0.696-0.787: 0.005. The method is suitable for solidifying the boron-containing concentrated waste liquid, and has the following remarkable characteristics that the molecular sieve is added into the formula and is used for adsorbing radionuclides, so that the leaching rate of the radionuclides is reduced; due to the fact that the nuclide leaching rate is reduced, more radioactive concentrated waste liquid can be contained in the unit volume, that is, the solidification volume containing rate of the concentrated waste liquid is increased and reaches 56.93%; PO42.5 cement is adopted as a curing base material, the PO42.5 cement is locally supplied, bulk cement can be provided, and the requirement for automatic loading and unloading of a cement curing system is met.
本发明具体涉及一种含硼废液水泥固化配方及其固定方法，包括普通硅酸盐水泥、熟石灰、添加剂、分子筛、浓缩废液和氯化钙，所述普通硅酸盐水泥、熟石灰、添加剂、分子筛、浓缩废液和氯化钙的重量比例为1:0.174～0.194:0.008～0.012:0.02:0.696～0.787:0.005。本发明适用于含硼浓缩废液的固化，具有以下显著特点：向配方中添加分子筛，用于吸附放射性核素，从而降低放射性核素浸出率；因核素浸出率降低，单位体积可以包容更多的放射性浓缩废液，即提高了浓缩废液固化体积包容率，浓缩废液固化体积包容率达56.93％；采用PO42.5水泥作为固化基材，PO42.5水泥有本地供货，可以提供散装水泥，满足水泥固化系统自动化装卸料要求。
