Abstract

The invention discloses a biogeochemical in-situ experimental device used for deep sea. The biogeochemical in-situ experimental device comprises a seawater sampling device, a reagent and cultivation bag system, a reagent selecting and quantifying device and a control device, and can realize the following five functions under the actions of a peristaltic pump, a solenoid valve and a rotary valve: afunction of introducing seawater into a cultivation bag, a reagent quantifying function, a function of introducing the reagent into the cultivation bag, a reagent runner cleaning function, an experimental stopping function and a stop agent cleaning function. The existing experimental process and experimental method in a lab are placed onto a sea bottom to perform in situ, so that the purposes ofregularly, quantitatively and automatically performing sample cultivation and experiment marking by the deep-sea biogeochemical experimental device in the deep sea in situ is realized. The cultivationbag in the to-be-recycled biogeochemical in-situ experimental device is taken out, and content change of reactants, reaction products and isotope tracer agents is analyzed in the lab, so that experimental data such as biogeochemical dynamic data of a deep sea in-situ environment can be obtained, and therefore, data support and basis are provided for disclosing a marine biogeochemical circulatingmechanism.

Description

technical field [0001] The invention relates to the technical field of biogeochemical cultivation experiments, in particular to a deep sea biogeochemical in-situ experimental device. Background technique [0002] With the development of science, more and more scientific issues focus on the marine field, including related fields such as biogeochemistry. [0003] Most of the current experimental samples are carried from the seabed to the sea surface through sampling methods such as samplers and water extractors, and finally biochemically cultured and analyzed in the laboratory. [0004] However, during this process, the samples have been separated from the original low-temperature, high-pressure living environment, and the validity of the samples is questionable. [0005] Through previous investigations, there are few reports on in-situ experimental devices similar to deep-sea biogeochemistry. Therefore, combined with the previous engineering requirements and principle desig...
