Description
技术领域
本发明涉及海洋设备防污技术，具体说是一种海洋关键设备光学窗口表面防污方法。
背景技术
近年来，随着海洋资源的大力开发，越来越多的海洋人工设施投入海洋中使用。各种珍贵的设备投入使用，其表面即会面临海洋污损生物附着，进而影响其正常运转与使用寿命等问题。据报道全球海洋污损生物大约有4000种，主要包括污损微生物(细菌，藻类等)和大型污损生物(藤壶和贝类等)。生物污损控制过程中，基膜和微生物膜的防治可以说是从源头上防治了生物污损。
目前适用于光学窗口的防污除污方法主要有：使用毒性材料，人工和自动清洗刷清理，由于材料选择性、会造成二次污染和增加人工成本等问题，使其使用受到了限制。有研究表明带有橡皮清洁刷的铜质保护盖能取得一定得防护效果，但是在海洋环境中铜腐蚀和毒性仍是一个不可忽视的问题。
发明内容
为解决上述问题，本发明目的在于提供一种海洋关键设备光学窗口表面防污方法。
为实现上述目的，本发明采用的技术方案为：
一种海水中光催化防污方法，通过光源照射在覆盖有光催化性能的不锈钢网的设备表面。
进一步的说，所述光源为紫外线灯或灯带中的一种。
进一步的说，所述光源为紫外线灯，紫外线波长为365nm。
进一步的说，所述光催化材料为镀银、BiOI、TiO2等膜的网状材料。
进一步的说，所述光催化材料基底材料为尼龙网或者铜网或者不锈钢网。
进一步的说，所述防污对象为细菌和微藻的防附着。
本发明与现有技术相比，具有以下优点及突出性效果：
该海水中光催化防污方法集防附着和杀灭微生物于一体，不仅能有效防治微生物的附着，而且运行简单、处理效率高、管理维修方便。通过光催化装置防污，即利用光催化膜产生的活性氧自由基对海水中的微生物(细菌、微藻、病毒)进行杀灭分解，无离子释放，不会造成二次污染。其结构简单，易拆卸，有很好的实用性。
附图说明
本发明用的部分附图用来提供对本发明的进一步理解，
图1为本发明实施例提供的防污方法示意图；
图2为本发明实施案例提供的有无钢网覆盖的玻璃表面数码照片图(a：无光照；b：光照)；
图3为本发明实施例提供的表面生物膜显微镜图。
具体实施方式
以下通过具体的实施例对本发明作进一步说明，有助于本领域的普通技术人员更全面的理解本发明，但不以任何方式限制本发明。
实施例1：
将BiOI薄膜修饰的30目、200目、800目不同316L钢网贴在玻璃表面，玻璃另一半不加钢网覆盖，悬挂于蓝藻培养基中，底部用UV-LED灯照射。30℃恒温培养箱中培养14d。
将试样取出，用肉眼和显微镜观察，研究微生物附着量。从图2红色虚线处可发现有一规则线，明显看出用镀有BiOI薄膜的316L不锈钢网覆盖处，生物膜附着明显减少。
由上述蓝藻中培养14d后不同试样表面形貌荧光显微镜观察：
不加光照a)空白玻璃表面，b)钢网覆盖玻璃表面，c)钢网表面；
光照d)空白玻璃表面，e)钢网覆盖玻璃表面，f)钢网表面光照条件下。
由上图3可见，无光照下，无覆盖的玻璃表面(3a)生物膜附着比钢网覆盖的玻璃表面(3b)多，说明钢网对玻璃表面有一定的防污效果；光照下，无覆盖的玻璃表面(3d)生物膜附着增加，钢网覆盖的玻璃表面(3e)未见明显的生物膜说明钢网对玻璃表面有很好的防污效果。进一步发现光照下，如图3f所示，钢网表面生物膜附着明显比图3c所示无光照条件下表面生物膜更薄更少，说明光照条件下具有光催化性能的薄膜能产生活性自由基能起到很好的防污作用。
