Description

Technical Field

[0001] The present invention relates to the technical field of marine environmental protection, and in particular to an online measurement test device for simulating a thermally driven subglacial water change process. Background Art

[0002] The Bohai Sea is the world's lowest latitude frozen sea area, and Liaodong Bay is the most severely iced area in the Bohai Sea. Ice lasts approximately four months each year, and during heavy ice periods, the area is almost entirely covered by sea ice. Sea ice significantly alters the spatial and temporal distribution of pollutants by affecting their local migration, transformation, and regional transport, impacting pollution levels, the ecological environment, and emergency risks in Liaodong Bay and the entire Bohai Sea to varying degrees.

[0003] On May 18, 2018, General Secretary Xi Jinping proposed "comprehensive governance of the Bohai Sea" in his important speech at the National Conference on Ecological and Environmental Protection. On June 16, 2018, the "Opinions of the CPC Central Committee and the State Council on Comprehensively Strengthening Ecological and Environmental Protection and Resolutely Winning the Battle Against Pollution" emphasized the need to "focus on promoting comprehensive governance of estuaries and bays in the Bohai Sea, including Bohai Bay, Liaodong Bay, Laizhou Bay, the Liaohe Estuary, and the Yellow River Estuary." On December 11, 2018, the "Action Plan for Comprehensive Governance of the Bohai Sea" was issued with the approval of the State Council. The "Implementation Opinions of the CPC Liaoning Provincial Committee and the Liaoning Provincial People's Government on Comprehensively Strengthening Ecological and Environmental Protection and Resolutely Winning the Battle Against Pollution" explicitly stated the need to "win the battle for comprehensive governance of the Bohai Sea, focusing on rectifying pollution in estuaries and bays such as Liaodong Bay and the Liaohe Estuary." This initiative has evolved from decision-making and deployment to concrete implementation.

[0004] Sea ice is a crucial ecological and environmental factor in the Bohai Sea, particularly in the Liaodong Bay area, covering the entire bay and one-third of the year. Previous studies have shown that the entire process of sea ice freezing, migration, and melting has varying degrees of significant impact on the water quality beneath the ice. However, systematic research into the mechanisms by which sea ice formation and melting influence water quality, as well as related evaluation methods, has not yet been conducted. This results in a lack of water quality monitoring and evaluation methods for both winter (when sea ice forms and freezes) and spring (after sea ice melts), which directly impacts pollution prevention and control efforts.

[0005] Previous studies have shown that the mechanism and extent of the impact of sea ice's growth and migration on surface water quality are influenced by natural environmental factors such as ice conditions and hydrodynamics, as well as the underlying seawater quality. Research and application of the impact of sea ice on surface water quality require answers to three questions: "Does it have an impact?", "How does it affect it?", and "To what extent?" This requires consideration of the thermodynamic processes of sea ice formation and melting and the dynamics of sea ice drift. This involves theoretical foundations based on the microstructure of sea ice and data from water quality monitoring in ice-covered areas. Direct measurement of subglacial water quality during in-situ freezing is limited by on-site sampling and monitoring techniques, and data continuity and representativeness of ice conditions cannot be guaranteed. Therefore, indoor simulations are needed to investigate the migration of various pollutants between ice and water during different freezing processes. In particular, continuous monitoring data on the changes in pollutant concentrations in subglacial water during different freezing processes should be focused on to analyze the influence of the freezing process and the environment on pollutants in surface seawater.
