核电厂冷源系统化学加药法海生物防治方法建议

Suggestions on Marine Biological Control Methods by Chemical Dosing in Cold Source System of Nuclear Power Plant

滨海核电厂通常采用投加次氯酸钠方法来抑制海水循环水系统的海生物生长与附着。介绍了随着核电运行时间增加,加氯防治出现的问题,并对非氧化杀生剂的种类、应用案例以及非氧化杀生剂的监测方式进行了阐述,建议采用定期投加非氧化性杀生药剂和次氯酸钠相结合的方式,以保证核电海水循环系统中的海生物防治效果。

In seaside nuclear power plants,sodium hypochlorite is usually added to inhibit the growth and adhesion of marine biological in seawater circulating water system.This paper introduces the problems of chlorination prevention and control with the increase of nuclear power operation time.The types,application cases and monitoring methods of non-oxidzing biocides are described.It is suggested to regularly add non-oxidzing biocides and sodium hypochlorite to ensure the effect of marine biological control in seawater circulation system of nuclear power plant.
