【摘要】：近年來抽水蓄能電站中爆發(fā)了一系列的淡水殼菜(Limnoperna fortunei,學(xué)名沼蛤)生物污損問題,嚴(yán)重影響電站的安全生產(chǎn),引起了廣泛關(guān)注。本文基于國內(nèi)外沼蛤防治研究經(jīng)驗,結(jié)合工程實例中沼蛤的兩類污損問題,分享最新的防附著涂料及生態(tài)水力學(xué)方法在抽水蓄能電站中沼蛤入侵防治方面的試驗成效。針對大管徑大流量的引水隧洞等結(jié)構(gòu),沼蛤污損防治可以考慮采用能夠有效防止沼蛤附著,且抗侵蝕性和環(huán)保性、耐久性等多個方面的綜合效果良好的襯砌材料,如SK-聚脲和SK-環(huán)氧YEC。針對小管徑小流量的技術(shù)供水系統(tǒng),沼蛤的防治可采用本文提出的集生物附著法、生物沉降法和湍流滅殺法于一體的綜合防治裝置對水流攜帶的幼蟲進行吸附、沉降、滅殺,從而降低幼蟲進入技術(shù)供水系統(tǒng)的風(fēng)險。
[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引言抽水蓄能電站是為了解決電網(wǎng)高峰、低谷之間供需矛盾而產(chǎn)生的,是間接儲存電能的一種方式。它在用電低谷時用過剩電力將水從下水庫抽到上水庫儲存起來,然后在用電高峰時將水放出發(fā)電,并流入下水庫。此外,抽水蓄能電站還能擔(dān)負(fù)調(diào)頻、調(diào)相和事故備用等動態(tài)功能,是電網(wǎng)運行管
