去除放射性废水中硼的试验研究

Experimental Study on Removal of Boron from Radioactive Wastewater

随着我国核电事业的发展,核电站对环境的影响也越来越受到重视,除核电站特有的放射性释放外,各审管部门也加强了对于常规污染物的审管力度,其中最受关注的是核电站废水中的硼排放。压水堆核电站排放废液中所含的硼并没有被活化,不带有放射性,因此不会对人体产生放射性辐照危害。饮用水标准不适用于核电站废液排放,但是对于内陆核电站,废水受纳水体往往兼做灌溉水水源,必须考虑到硼对环境和公众的影响。本文通过调研了水中硼的去除的通用技术,并通过试验研究验证部分技术的去除效果。

With the development of nuclear power industry in our country, more and more attention has been paid to the environmental impact of nuclear power plants. In addition to the radioactive re-lease from nuclear power plants, various management departments have also strengthened their efforts to monitor conventional pollutants. One of the most important concerns is the boron discharge from wastewater from nuclear power plants. Boron in waste liquid from nuclear power station is not activated and radioactive, so it will not cause radiation damage to human body. The drinking water standard is not suitable for the waste liquid discharge of nuclear power station, but for inland nuclear power station, the storage water of treated wastewater is often used as irrigation water source, so the influence of boron on the environment and the public must be taken into account. In this paper, the general removal technology of boron in water is investigated, and the effect of partial removal technology of boron in water is verified by experimental research.
