Abstract

The invention discloses a water pollution river sediment in-situ remediation device and method, and belongs to the technical field of water pollution treatment and environmental remediation. The device comprises a vertical hollow reaction column, ORC reaction beads are placed in the hollow reaction column, hollowed-out parts are formed in the peripheral column surface of the hollow reaction column, water flows into the hollowed-out parts to react with the ORC reaction beads to release oxygen, a placement platform is arranged at the upper end of the hollow reaction column, and two layers of popup devices are mounted in the center of the placement platform; deodorizing flora gel beads are distributed on the ORC reaction bead popup devices around the deodorizing flora gel bead popup devices in a surrounding manner; the lower end of the hollow reaction column is a conical device fixing bottom end, a disturbance device is arranged on the upper portion of the device fixing bottom end and comprises a submersible motor located in the middle, and four telescopic mechanical arms are evenly distributed on the periphery of the submersible motor and connected with the submersible motor. The problems of short repair and maintenance time and odor generation during treatment of a common device are solved.

Description

technical field [0001] The invention belongs to the technical field of water pollution control and environmental restoration, and in particular relates to a device and method for repairing black and odorous river bottom mud. Background technique [0002] In the water environment pollution, black and odorous water body is a relatively serious pollution phenomenon. When the water body is polluted, some pollutants accumulate day by day, and enter into the bottom mud of the water body through sedimentation or adsorption with particulate matter. The bottom mud is the ultimate storage place for pollutants. With continuous accumulation and enrichment, the concentration of pollutants in the bottom mud is often several orders of magnitude higher than that in the overlying water. Sediment pollution will affect the water quality of the river for a long time. The pollutants in the sediment and the overlying water maintain a dynamic balance of adsorption and release. Once the environment...
