摘　　要：海洋环境监测工作中大部分仪器设备放置海水里,都会或多或少地受到海洋生物附着的影响。生物附着物的生长速度有时非常快,覆盖海底观测设备及传感器的测量单元,对测量效果产生不利影响,使得观测数据持续漂移、降低数据质量、导致传感器逐渐失效。生物附着还会影响海洋设备的散热、水动力流场,并对机械结构产生腐蚀等。目前诸多防生物附着技术各有弊端,甚至产生环境污染问题。为此设计并组装基于紫外线杀菌原理的CTD防生物附着装置,明确各主要技术参数,应用在渤海夏季近岸海上比测试验,验证其对于大部分的海洋附着物具有良好的杀灭效果,可有效缓解生物附着对电导率传感器的影响,在海洋环境监测领域具有广泛的应用前景。In the marine environment monitoring practice, most instruments placed in the seawater will be more or less affected by the marine biofouling.Under some circumstances, the growth rate of the biofouling is so fast that the sensors of the equipment are covered, and the measurement results are adversely affected, including the continuous data drifting, declined data quality, and the gradually failed sensor function.In addition, the heat dissipation, hydrodynamic current field, and mechanical structure corrosion of the marine equipment can also be influenced by the biofouling.At present, the anti-biological adhesion technologies are inherent with their various drawbacks, and even cause the environmental pollution issues.A new CTD anti-biological attachment device is designed and assembled based on the principle of ultraviolet sterilization.The design, composition, index and application of the CTD anti-biological attachment based on UV disinfection principle are discussed.The off-shore field experiment in summer in the Bohai Sea indicate that it has excellent killing effect on the most marine attachments, and effectively alleviates the influence of biological attachments on conductivity sensors, which has a wide range of applications in the field of marine environmental monitoring.
