Problems solved by technology

The mathematical model established by the computer is to mathematically limit the water temperature, water flow and the general degradation law of organic matter that have been found in natural water bodies, and then simulate and predict the changes of pollutants and dissolved oxygen in the water body, but this cannot be done under realistic conditions. Do further research on the mechanism of lake eutrophication and organic matter degradation

Embodiment

[0030] A water environment simulation reactor based on the water-soil interface, its structure is as follows Figure 1-2 As shown, the reactor includes a reaction shell 1, a soil layer 16 is arranged on the inside, a partition 9 is arranged in the middle, a water inlet 5 is arranged on one side, and a water outlet 2 is arranged on the other side, and water flows from the water inlet 5 flows into the reactor and flows out of the reactor through outlet 2. The reaction housing 1 is also provided with a soil layer water outlet valve 3, the material of the reaction housing 1 is PVC material, and the partition plate 9 divides the reaction housing 1 into an upper cavity and a lower cavity, and the upper cavity is a dissolved oxygen zone. The lower cavity is an anaerobic zone, and the ratio of diameter to depth between the upper cavity and the lower cavity is 1:1-1:4. In addition, a flow meter is provided at the water inlet 5 to control the flow of water. The support plate 15 is used...

Abstract

The invention relates to a water environment simulation reactor based on a water-soil interface. The invention belongs to the technical field of water environment research. When a simulator hydraulic retention time of the device is the same with that of a natural water body, precise controls over different hydraulic conditions and environmental factors (temperature, DO or ORP, etc.) of the simulator are realized. Water passes through a water inlet port, a water inlet area A, a control zone, a water outlet area B, and a water outlet, and contacts soil or sediments in the device, such that natural water body environment can be simulated. Compared with prior arts, the reactor provided by the invention has the advantages of simple structure, easy operation, and low running cost. The reactor can be used in laboratory researches of water-soil contaminant migration, degradation mechanism, eutrophication process, heavy metal migration, and the like, and has wide application prospect.

Description

technical field [0001] The present invention relates to water quality, soil and environment, an experimental simulation device for natural water environment based on the above related disciplines, especially a water environment simulation reactor based on water-soil interface, which realizes the interface between natural water body and soil under laboratory conditions The process of material exchange. It can be used for research on the diffusion and migration of organic pollutants and heavy metals in water environments in different regions, and can also be used for research on eutrophic water bodies and their restoration processes and the establishment of related mathematical models. Background technique [0002] Environmental bulletins in recent years have shown that the eutrophication of major lakes in my country is very prominent; and the water bodies of rivers are also gradually deteriorating. Most of the water pollution is organic, and the main pollution indicators are...
