Problems solved by technology

[0002] At present, the distribution of fresh water resources is uneven in time and space, and the per capita fresh water resources are scarce. Especially in the eastern coastal areas, the exploitation of ground water resources is serious, which leads to the decline of ground water table, destroys the boundary between sea water and fresh water, causes local geological subsidence, and causes disasters.

Embodiment Construction

[0028] Such as figure 1 As shown, including flat tank, fresh water supply system, salt water supply system, adjustable height bracket, base flow simulation system, tidal wave generator and sampling hole. The fresh water tank 1 located on the ground in the fresh water supply system pumps water into the overflow tank 3 through the first submersible pump 2, passes through the overflow partition in the overflow tank 3 to make the groundwater more gentle, passes through the first water stop valve 5 and the second A glass rotameter 6 is connected to the flat water tank. The flat tank includes tank head, tank body, tank tail and tank bottom. The size of the simulation device is 4m×0.8m×0.3m. The tank body forms fresh water and salt water areas respectively through the water retaining partition 9, and the water level in the fresh water area is adjusted by a water level regulating device, and the adjustment hand wheel 4 controls the height of the water valve plate 8 through the up and...

Abstract

The invention discloses a device for simulating coast reservoir pollutant migration and a use method of the device. The device comprises a planar water trough, a fresh water supply system, a saline water supply system, a base flow simulation system, a sampling system and a tidal wave generator, wherein the fresh water supply system is connected with the head of the planar water trough; the salinewater supply system is connected with the tail of the planar water trough; the sampling system is connected with the body of the planar water trough; the base flow simulation system is positioned at the bottom of the planar water trough; the tidal wave generator is connected with the tail of the planar water trough. Compared with the prior art, migration of coast reservoir pollutants can be precisely simulated, not only are variable levels of fresh water and saline water monitored in real time, but also water inside the water trough is sampled in real time under a condition that a good overallsimulation environment is ensured, and migration rules of the pollutants at different flows, water levels and tidal water heads can be detected.

Description

technical field [0001] The invention relates to a device for migrating coastal pollutants, in particular to a device for simulating the migration of pollutants in a coastal reservoir and a method for using the device. Background technique [0002] At present, the distribution of fresh water resources is uneven in time and space, and the per capita fresh water resources are scarce. Especially in the eastern coastal areas, the exploitation of ground water resources is serious, which leads to the decline of ground water levels, destroys the boundary between sea and fresh water, causes local geological subsidence, and causes disasters. The construction of coastal reservoirs in coastal areas is an effective way to regulate and utilize water resources. It can make full use of coastal resources and obtain the advantage of larger reservoir storage capacity. [0003] The construction of coastal reservoirs can alleviate the contradiction of fresh water resources and achieve good socia...
