摘要:

近岸、河口和海湾水质浮标监测越来越受到关注, 但目前有关水质监测传感器的防污染技术的报道还很少。文章介绍了在珠江口水质监测浮标中使用的几种防污染方法。对于有光学窗口的监测仪器, 采用自动防污染装置可以清除窗口表面的污染物。对于不便于采用自动防污染刷的传感器, 根据情况分别采用防污染材料包络, 或者海水注入管路的防污染过滤头等方式, 也可以达到一定的防污染效果。对于长期水下观测仪器, 每隔一段时间还应进行舱体污染物的人工清洗, 以保证设备的正常使用。

Abstract:

Antifouling techniques are important for water quality monitoring sensors, especially for those sensors used in coastal and estuarine waters. In this paper, several biofouling prevention methods used for the Pearl River Estuary water quality monitoring buoys are introduced. For optical monitoring instruments, the automatic anti-biofouling brush can clear the pollutants on the surface of optical windows. For the sensors that cannot use automatic anti-biofouling brush, anti-biofouling material enveloping or anti-biofouling filter head of seawater injection pipeline could achieve limited anti-biofouling effect. To ensure normal operation of long-term underwater observation instruments, the instrument warehouse needs to be manually cleaned periodically.

Key words: water quality monitoring buoy, underwater sensor, biofouling protection method, Pearl River Estuary
