Description

Wharf water pollution and fouling organism integrated sampler Technical Field The invention relates to the technical field of sampling of water pollutants, in particular to a wharf water pollution and fouling organism integrated sampler. Background The dock and port area is the complex habitat where land-sea interactions are the strongest and is also the most closely-moving zone of offshore mankind. With the explosion of the global shipping industry and the aggravation of coastal industrial activities, dock waters are facing increasingly severe ecological environmental challenges, requiring pollution control and remediation. These challenges stem mainly from two aspects, namely, water pollution, including ballast water discharged from ships, domestic sewage, oil leakage, industrial pollutants from land areas, pesticides, persistent organic pollutants and the like, which are enriched in wharf water bodies and form a direct threat to water quality safety, and biological fouling and foreign species invasion, water structures (such as pile foundations and revetments) of wharf provide ideal adhesion matrixes for fouling organisms, and meanwhile, the discharge of ship ballast water also becomes a main way for the cross-regional transmission of foreign harmful organisms (such as red tide algae and barnacles) and causes unbalance of local ecosystems and reduction of biological diversity, so that sampling of wharf periphery is required for detection. When sampling shallow layer fouling organisms, after the tide is returned, the pile foundation or the upper layer part of the revetment is exposed, researchers can directly scrape the organisms into the collecting net bag by utilizing a shovel blade, a scraper or a steel wire brush, the time dependence on the tide is strong, and the samples below the low tide line cannot be obtained. When sampling deep fouling organisms, scientific researchers or operators usually need to submerge under water to directly finish the sampling task. However, in the offshore water area environment such as wharf, due to the cloudiness of the water body and more suspended matters, the underwater visibility is often very low, the safety risk of diving operation is increased, the accuracy and the integrity of sampling data can be possibly affected, and potential threat is formed to the personal safety of diving personnel.
