Abstract

The invention relates to a river dredging and pollution diffusion prevention device. The device comprises a pollution interception net, a bottom mud purifying agent adding device and a pollution concentration monitoring device, wherein the pollution interception net is arranged in a water body behind dredging equipment, a traction rope of the pollution interception net is connected with the dredging equipment, a plurality of adsorption material ropes are arranged below a buoy to form the interception net, and a sinking hook is connected with the adsorption material ropes; the bottom mud purifying agent adding device is connected with a nozzle pipe through a metering device and a hose, and the nozzle pipe is arranged below the buoy; the pollution concentration monitoring device is arranged in the water body at the rear end of the intercepting net and is connected with the buoy; and when the pollution concentration exceeds a set value, the bottom mud purifying agent adding device is controlled to add a bottom mud purifying agent into the water body. The device has a good interception effect on pollutant diffusion caused by disturbance of bottom mud in the construction process of the dredging equipment during dredging of urban small and medium-sized inland rivers, meanwhile, pollution diffusion can be further reduced by adding a bottom mud purifying agent in a reverse control mode, and the pollution bottom mud which is not removed is reduced; and dredging and bottom mud purification are further combined to achieve synchronous construction.
