Problems solved by technology

Most ring-shaped sinks use concentric ring-shaped sinks, which are driven by the rotation of the upper and lower plates or the inner and outer walls to drive the water flow, and the structure is more complicated.
Due to the characteristics of the structure of the annular tank, the cen...

Abstract

The invention relates to an annular water tank device for simulating sediment pollutant resuspension release. The annular water tank device comprises an annular water tank main body, a base, a rotary power device, a lifting power device and a flow velocity measurement and sampling device, wherein the annular water tank main body is arranged on the base; the lifting power device is arranged in the center of the base; the rotary power device is arranged at the upper end of the lifting power device; the flow velocity measurement and sampling device is arranged on the upper part of an outer wall of the annular water tank main body. The annular water tank device is small in size and can be conveniently moved even can be transported to be subjected to field sampling for test, a storage reservoir is not needed, a water pump is not needed, a small number of needed samples are needed, the flow velocity is conveniently and feasibly adjusted, observation and operation are convenient, mechanical interference is avoided, and infinitely long water flow can be simulated. An eccentric shear ring device floating on water surface is adopted in the device, and water flow in the annular water tank can be kept horizontal, so that secondary flow development is effectively suppressed.

Description

technical field [0001] The invention relates to an annular water tank device for simulating the resuspension and release of sediment pollutants, belonging to the fields of water conservancy engineering and environmental science. Background technique [0002] Water environmental problems such as water eutrophication and heavy metal pollution are becoming more and more prominent. The sedimentation and accumulation of pollutants in the sediment of rivers and lakes makes the endogenous pollution of the sediment more and more serious, especially in estuary areas with complex hydraulic conditions. Endogenous releases from contaminated sediments are increasingly evident. For shallow lakes and rivers subject to large hydrodynamic disturbances, pollutants deposited in the sediment of the water body are prone to resuspension, which has a greater impact on the water environment of the entire water body. Therefore, it is necessary to build a model to simulate hydraulic conditions and s...
