Problems solved by technology

However, these methods have the following main problems for the study of the interaction between microorganisms and sediments: 1) The sediments are directly mixed with the microorganisms, and the microorganisms may be directly adsorbed on the surface of the sediments. Including the organic components of the microorganisms themselves; 2) separating the active substances secreted by the microorganisms from the microorganisms themselves, and then cultivating these active substances with the sediments, cannot accurately and real-time simulate the interaction between microorganisms and sediments, such as in the separation of active substances Under the action of substances, the sediment releases nutrients, etc., and then acts on microorganisms, etc.

Abstract

The invention relates to an experiment device for analyzing deposits, and particularly discloses an experiment device for simulating interactions between microbes and deposits. The device includes a microbe culture and dialysis apparatus and a deposit culture chamber. The microbe culture and dialysis apparatus includes a microbe culture pool and a dialysis apparatus. The dialysis apparatus includes a dialysis bag. Two ends of the dialysis bag are sealed through sealing assemblies. The sealing assemblies are provided with standard connectors to which hoses can be connected. The standard connectors achieve communication between the dialysis bag and the outside. The deposit culture chamber includes a deposit storage chamber and a tapered sand core apparatus. The microbe culture and dialysis apparatus and the deposit culture chamber are communicated through a connection hose. The invention also discloses an experiment method adopting the device and applications thereof. The device and themethod achieve real-time dialysis and filtration separation for the microbes and the deposits, and achieve simulation research on interactions between microbe active substances and deposits.

Description

technical field [0001] The invention relates to an experimental device for analyzing sediments, in particular to an experimental simulation device and an experimental method for the interaction between microorganisms and sediments. Background technique [0002] Microbes play an important role in the water environment, such as the cycle of nutrients in lakes and the decomposition of various chemical substances, and can be said to be the main driving force for material cycles in lakes. Microorganisms in the water environment, such as algae and bacteria, through their own metabolic activities, including the mutual transformation between inorganic and organic substances, and the circulation of various elements and compounds between microorganisms-water bodies-sediment, etc., these directly affect the relationship between water and water. The occurrence form and migration and transformation process of nutrients such as carbon, nitrogen, and phosphorus in sediments affect the nutr...
