烟台开发区近海不同海底管道材料附着污损生物的比较

摘要

2010年5～7月在烟台开发区近海针对5种材料(环氧板、高密度聚乙烯管、玻璃钢管、碳钢管、水泥砖)进行了污损生物挂板试验.共鉴定出污损生物16种,其中优势种为海筒螅、阔口隐槽苔虫、紫贻贝和东方缝栖蛤.4种海底管道材料中(不合环氧板),水泥砖的污损生物覆盖面积率最大,玻璃钢管和高密度聚乙烯管次之,碳钢管最小,7月初～7月中旬为污损生物附着盛期.建议取排水管道材料选用玻璃钢管或高密度聚乙烯管.%The panel test on fouling organisms on five materials (epoxy board,HDPE,FRP,carbon steel and cement block) was carried out in offshore of Yantai Economic and Technological Development Zone(ETDZ) from May to July 2010.A total of 16 fouling organism species were recorded,among which Tubularia marina,Cryptosula pallasiana,Mytilus edulis and Hiatella orientalis were the dominant species.Among four pipe materials in seabed,cover area of the fouling organism on cement bricks was the largest,followed by FRP,HDPE,and carbon steel.The attachment of fouling organisms reached the peak from early July to mid-July.FRP or HDPE is recommended for water supply and drain pipe.
