The invention belongs to the technical field of the water
ecological environment, and particularly to a device and a method for stimulating
pollutant transport and upstream salty water of a riverway with a repeated tidal flow. The device comprises an upstream flow control device, a middle water tank device and a downstream tidal flow control device, and is characterized in that the upstream flow control device comprises a water inlet
pipe, a constant flow water tank and an upstream
water level control water tank; the middle water tank device comprises a water tank body, a speed measuring device and a
pollutant sewage inlet tank; the downstream tidal flow control device comprises a tide
water level control water tank, a tide
backflow stimulation water tank, a compensation or
seawater salinity stimulation water tank; the upper end of the water tank body is connected with the upstream
water level control water tank while the lower end thereof is connected with the tide water level control water tank; the tide water level control water tank is connected with the tide
backflow stimulation water tank; the compensation or
seawater salinity stimulation water tank is connected with the tide
backflow stimulation water tank. The device and the method for stimulating
pollutant transport and upstream salty water of riverway with the repeated tidal flow can stimulate transport and
diffusion rules of the pollutants in the riverway with the repeated tidal flow (the upstream salty water rules), and can be widely applied to the
simulation tests in the technical field of the water
ecological environment.
