Abstract

The invention provides an experiment apparatus used for researching a technology for preventing and controlling the nutrition salt release of deposits. The experiment apparatus comprises: a prevention and control experiment container, wherein the sidewall of the prevention and control experiment container is provided with a sealable and closeable channel opening; a separation sheet being suitable for being inserted from the channel opening and being applied to the inner wall of the prevention and control experiment container; and a lifting mechanism arranged on the sidewall of the prevention and control experiment container and being suitable for driving the separation plate to rise to the top of the prevention and control experiment container. The experiment apparatus used for researching a technology for preventing and controlling the nutrition salt release of deposits can strictly simulate field environment conditions in order to solve the technical problem of lack of experiment apparatuses and methods used effectively simulating the prevention and control of modification materials on the nutrition salt release of the deposits in the prior art and to obtain the a complete modification material and deposits after the prevention and control experiment, and is good for researching the prevention and control process and mechanism of various modification materials on deposits, and the change conditions of the modification material and deposits after the experiment.

Description

technical field [0001] The invention belongs to the technical field of pollution ecological restoration and pollutant reduction control, and in particular relates to an experimental device for research on the technology research of sediment nutrient salt release resistance control. Background technique [0002] The eutrophication of lakes and reservoirs is a difficult problem in the pollution control of lakes and reservoirs. The eutrophication of water bodies will cause great damage to aquatic ecosystems and bring a series of environmental problems. The high nutrient content is one of the main reasons for the eutrophication of lakes and reservoirs. Analyzed from the source, the nutrient salts in the water body of the lake and reservoir mainly come from the river basin, atmospheric deposition and sediments in the lake and reservoir. Among them, the release of sediment nutrients has a great influence on the level of nutrients in lakes and reservoirs, and is an important sourc...
