无人监测船在城市内河水质监测中的应用

摘要

采用无人船监测技术结合镇江市内河水质状况普查工作,大于120 h的航行试验,总航行里程约为90 km,对建成区水体中的氨氮( NH3-N)、溶解氧( DO)、氧化还原电位( ORP)和浊度进行原位监测,结果表明,通过合理选择搭载相应的测量电极,无人监测船能够满足地表水测量数据准确度的要求,同时可实现研究区域的监测全覆盖,提升了地表水环境监测的工作效率。%Unmanned ship is a new type of unmanned automatic monitoring platform, which can be equipped with the corresponding measurement electrode to automatically monitor the status of water quality. This paper used unmanned ship to carry out in situ moni-toring of ammonia nitrogen, dissolved oxygen, oxidation reduction potential and turbidity in the waters of built-up area of Zhenjiang city. The results showed that the unmanned ship meets the need of surface water monitoring if it be equipped with the corresponding measuring electrode. The unmanned monitoring vessels can be applied to water environmental monitoring work in the inland city.
