超标放射性洗衣废水的处理装置及其试验研究

Experimental Study on Treatment Equipment of Over-Standard Radioactive Laundry Wastewater

放射性洗衣废水是核电站中主要的液态流出物,其放射性水平很低。山东海阳核电站采用非热能处理技术,使用了无机离子交换剂–沸石作为吸附和交换材料,去除水中的放射性核素。本文介绍了在超标放射性洗衣废水处理装置运至海阳核电站前的168小时验证试验研究,证明了该装置工艺设计合理,设备处理能力和指标达到了设计要求。

The radioactive laundry wastewater is the main liquid effluent from the nuclear power plant, and the radioactivity level is very low. Haiyang Nuclear Power Plant uses non thermal treatment tech-nology, using inorganic ion exchanger zeolite as adsorption and exchange material to remove ra-dionuclide from this kind of water. In this paper, a 168-hour verification test was carried out before the equipment was shipped to the Haiyang Nuclear Power Plant, which proved that the process design of the equipment was reasonable, the capacity and index of the equipment met the design requirements.
