Suspended river water heavy metal pollution treatment device and use method thereof

Abstract

The invention discloses a suspended river water heavy metal pollution treatment device in the technical field of river water pollution treatment. The device comprises a transverse plate, a U-shaped frame is symmetrically fixed at the bottom end of the transverse plate, conical rods are fixed at the bottom ends of the two sides of the U-shaped frame, a screw rod is rotatably arranged on the transverse plate, a rotating handle is fixed at the left end of a rotating shaft, and a threaded cylinder sleeves the outer side of the bottom of the screw rod. A horizontal plate is fixed at the bottom end of the threaded cylinder, a sliding groove is formed in the bottom end of the horizontal plate, a sliding block is arranged in the sliding groove in a sliding mode, a movable plate is fixed to the bottom end of the sliding block, a handle is fixed to the left end of the movable plate, a plurality of connecting ropes are connected to the bottom end of the movable plate, a pollution treatment mechanism is connected to the bottom end of each connecting rope, and a locking mechanism is arranged on the movable plate; and a slot is formed in the bottom end of the horizontal plate. The movable plate is arranged, the movable plate is slidably connected with the sliding groove in the bottom of the horizontal plate through the sliding block, the movable plate is pulled to the left side, the pollution treatment mechanisms are moved to the shore side, and taking-back operation is facilitated.

Description

technical field [0001] The invention relates to the technical field of river water pollution control, in particular to a suspension type river water heavy metal pollution control device and an application method thereof. Background technique [0002] In recent years, my country's economy has developed rapidly, and the water resources needed in various fields have gradually increased. At the same time, the discharge of industrial wastewater and domestic wastewater has also increased day by day, which has seriously affected the river and caused serious pollution. The ecological environment around the river and the Residents' production and life are seriously threatened. Under such a background, various localities have begun to increase the intensity of river regulation, the main purpose is to better protect the ecosystem of the river and control water pollution. Heavy metals are one of the important pollutants with potential hazards in water bodies. Sulfide precipitation metho...

Problems solved by technology

[0004] The above-mentioned scheme still has disadvantages: in the above-mentioned scheme, the device is suspended on the water surface. Since the device is a certain distance from the river bank, it is inconvenient to retrieve the device. It is necessary to use ships and other vehicles to fix and retrieve the device, which is inconvenient to use.
