The electro-deionizing mechanism of packed bed electrodialysis and the transferation behavior of some radioactive nuclides passing through the electrodialyzer were investi-; gated. The formulae for calculating the deionizing current efficiency were derived and proved by experiments. A DPC process including electrodialysis and packed bed electro-dialysis for the treatment of lowrlevel radioactive waste water was proposed with the operating data listed.

Tritiated water is one of the radioactive wastes which are produced at atomic facilities. the chemical property and the physical behavior of tritiated water art the same as that of ordinarg water, consequently, it is not easy to separate tritium from radioactive waste water in the way as to remove other radio chemical nu- lides. It is considered a practicable method to fix tritiated water by applying tl technique of cement hydration. Generally speaking, 3 CaO·2 S_iO_2·3 H_2O and Ca (OH)_2 are produced at cement hydrating, which means, for example, 25 gr-ams of water will be consumed by 100 grams of cement. Therefore, making use of this behaviour, it may be expected that tritiated water be fixed as the component of the hydrated cement structure. Although it has already been found through simple experiments that much tri- tiated water moves out to surrounding water, yet with the hydration of Portland cement, tritiated water will be incorporated in. So an attempt has been made to study the mechanism of the transfer of tritiated water fixed with cement. This report has shown the results and conditions of those essential experiments in connection with the behaviours of various kinds of cement curing period, soakn- ing perod, presence of gel. water, and the salt and alkali concentrations in surrou- ding water, etc.

从原子能设备中产生的放射性废物之一,是含氚废水。氚水的化学性质和物理特性与普通水是相同的,因此要从放射性废水中,象其它放射性核素一样,把氚水分离出来是困难的。我们认为使用水泥水化固定氚水是一个行之有效的方法。一般说来,水泥水化主要产生3CaO·2SiO_2·3H_2O和Ca(OH)_2,即每100g水泥中的水将消耗25克水,因此利用这一性能,期待氚水能作为水泥水化后结构中的组份而固定。虽然利用简单的试验,已经发现大量氚水转移到周围水中。但是,使用波特兰水泥的水化,氚水还是被溶合进去了,因此,我们试图了解,用水泥固定氚化水转移现象的机理。本报告中,我们示出了包括下述几方面的基本试验的结果和条件,即:不同水泥的作用,养护期,水中浸渍时间,凝胶水存在时的情况,以及周围水中盐和碱的浓度等。

This is the contiunue work of the survey on pollution ofthe sediment in a river to which radioactive waste water from a thoriummill is released.The authors investigated radioactive pollution by determin-ing γ-exposure rate on the sediment surface.It was found that the pollutioncould coinsided with gauss distribution.Some 40 Cm deep core samples we-re counted and showed to be the maximum depth polluted of about 20 Cm.The parameters of waste water during the period from 1975 to 1979were statistically analysed.The pH is normally-distributional((?)=8.0,(?)=2.0),while the concentrations of Th,U and Ra are Log-normally-distrib-utional.

本文是对某钍水冶厂放射性废水造成江浅滩底质泥污染的第二篇报告。作者测定了底质泥表面上的γ照射量率,认为底质泥的污染可能是符合高斯分布的。根据深度为40厘米泥芯样的测量结果,表明最大污染层深度为20厘米左右。作者对1975—1979年期间的废水监测资料进行了统计分析,发现 pH 值呈正态分布((?)=8.0,(?)=2);钍、铀和镭的浓度呈对数正态分布。
