摘要
近年来,水利工程遭受沼蛤污损的问题日益突出。污损生物沼蛤附着于输水管道等水工建筑物后会腐蚀附着面,降低管道等输水建筑物的过流能力,使阀门、闸门等关键设施启闭困难,严重影响水利工程的安全运营。文章通过实验分析了沼蛤的几何特征及附着特点,探讨沼蛤附着特性及基于附着特性的生态防治措施。研究表明,沼蛤体长与体宽、体高呈线性相关,体长与体重呈指数相关;黏附率与基质粗糙率之间呈正相关关系,基质越粗糙越易附着;附着基质粒径小于10 mm时能够明显抑制沼蛤黏附。
In recent years,the biofouling problem of water projects suffering from the offset of limnope rna fortune i was become increasingly prominent. Limnope rna fortune i,the fouling organisms,attach togetherto the surface of the hydraulic structures such as water conveyance piping,valves,and gates etc.,whichcan corrode the adhesion surface,reduce the capacity of pipeline flow,and make it difficult for the key fa-cilities like the valves and gates to open or close. All of this seriously affects the safe operation of waterprojects. Through experiment this puper analyzed the geometrical characteristics and adhesion characteristicsof limnope rna fortune i,and explored the adhesion properties of limnope rna fortune i as well as the adhe-sion prevention measures based on ecological characteristics. From the experiment we can draw the follow-ing conclusions. The length of limnope rna fortune i has a linear correlation with its body width andheight,and is index-linked with its weight;The rough matrix rate and adhesion rate are in a positive cor-relation,and the rougher the matrix is,the easier it is limnope rna fortune i to attach;The sandy matrix,which matrix size is less than 10 mm,can obviously suppress the adhesion of limnoperna fortunei.
