核电厂取水隧洞翡翠贻贝污染防治建议

Suggestions on Prevention and Control of Perna Viridis Pollution in the Seawater Intake Tunnel of Nuclear Power Plant

某核电厂循环冷却海水取水隧洞主要污染海生物为翡翠贻贝,为不影响取水流道的通流面积,降低循泵跳泵风险,需对翡翠贻贝进行有效防控。本文通过现场加药优化试验,分别得到了冲击性加氯(次氯酸钠)、连续加氯、冲击性加非氧化性杀菌剂对翡翠贻贝的杀灭效果,为取水隧洞海生物污染防控提供了基础数据。

The main polluted marine organism of the seawater intake tunnel in the cold source system of the nuclear power plant is perna viridis.In order not to affect the flow area of the seawater intake tunnel,it is necessary to effectively prevent and control perna viridis.In this paper,we have carried out the killing experiments of perna viridis through the on-site experimental devices,and the killing effects of sodium hypochlorite(continuous dosing and discontinuous dosing)and common non-oxidzing biocides on perna viridis were obtained,which provided basic data for the prevention and control of perna viridis in the nuclear power plant.
