【摘要】：近年来抽水蓄能电站中爆发了一系列的淡水壳菜(Limnoperna fortunei,学名沼蛤)生物污损问题,严重影响电站的安全生产,引起了广泛关注。本文基于国内外沼蛤防治研究经验,结合工程实例中沼蛤的两类污损问题,分享最新的防附着涂料及生态水力学方法在抽水蓄能电站中沼蛤入侵防治方面的试验成效。针对大管径大流量的引水隧洞等结构,沼蛤污损防治可以考虑采用能够有效防止沼蛤附着,且抗侵蚀性和环保性、耐久性等多个方面的综合效果良好的衬砌材料,如SK-聚脲和SK-环氧YEC。针对小管径小流量的技术供水系统,沼蛤的防治可采用本文提出的集生物附着法、生物沉降法和湍流灭杀法于一体的综合防治装置对水流携带的幼虫进行吸附、沉降、灭杀,从而降低幼虫进入技术供水系统的风险。
[Abstract]:In recent years, there have been a series of pollution problems of Limnoperna fortuneii (Limnoperna fortuneii) in pumped storage power stations, which seriously affect the safety of power plant production. Based on the research experience of prevention and control at home and abroad, this paper combined with engineering examples of two kinds of pollution problems of Marsh clam. To share the latest anti-adhesion coating and ecological hydraulics methods in the pumped-storage power station in the prevention and treatment of Marsh clam invasion results, aiming at large pipe diameter and large flow of diversion tunnel and other structures. The prevention and control of pollution can be considered by using lining materials which can effectively prevent clam adhesion, corrosion resistance, environmental protection, durability and other aspects of the comprehensive effect. For example SK-polyurea and SK-epoxy-YEC. for the technical water supply system with small pipe diameter and small flow, the prevention and cure of Marsh clam can be carried out by means of collecting biological attachment method proposed in this paper. The integrated control device with biological sedimentation method and turbulent killing method can absorb, settle and kill the larvae carried by the water flow, thus reducing the risk of the larvae entering the technical water supply system.

【正文快照】： 0引言抽水蓄能电站是为了解决电网高峰、低谷之间供需矛盾而产生的,是间接储存电能的一种方式。它在用电低谷时用过剩电力将水从下水库抽到上水库储存起来,然后在用电高峰时将水放出发电,并流入下水库。此外,抽水蓄能电站还能担负调频、调相和事故备用等动态功能,是电网运行管
