This invention provides a device for chemical dewatering of sludge in wastewater treatment plants, comprising a treatment box with a chemical tank mounted on top. A rotating base plate is rotatably connected to the bottom of the chemical tank. Debris shovels are fixedly connected to both sides of the bottom of the chemical tank. A support frame is fixedly connected to one side of each debris shovel. Rolling rollers are rotatably connected to both sides of the support frame. A stirring motor is fixedly connected to one side of the chemical tank. A stirring component is fixedly connected to the power output end of the stirring motor. The bottom of the stirring component is fixedly connected to the rotating base plate, and a drive gear ring is fixedly connected to the bottom of the stirring component. The stirring motor drives the stirring component and the rotating base plate to rotate, mixing the chemical powder with warm water within the chemical tank. Undissolved lumps are squeezed into an arc-shaped area by the debris shovels, while the drive gear ring meshes with the rolling gears, driving the rolling rollers to rotate and crush the lumps outwards. This ensures thorough pulverization and fusion of the chemical powder, preventing lumps from entering the wastewater treatment system and improving mixing efficiency and chemical powder utilization.

This utility model discloses a fracturing flowback fluid flocculation sedimentation tank, relating to the field of fracturing flowback fluid flocculation sedimentation technology. It includes: a tank body, an inlet, a dosing port, a sludge discharge port, and a servo motor. The inlet and dosing port are located at the top of the tank body, and the sludge discharge port is located at the bottom center of the tank body. The servo motor is fixedly located at the upper center of the tank body, and its drive rod passes downward through the top center of the tank body and enters the interior of the tank body. A first conical guide plate and a second conical guide plate are fixedly mounted on the drive rod, with the dosing port pointing towards the first conical guide plate and the inlet pointing towards the second conical guide plate. By fixing the first and second conical guide plates on the drive rod, corresponding to the dosing port and the inlet respectively, this application allows the flocculant and fracturing flowback fluid to smoothly enter the tank body. Simultaneously, the two guide plates rotate together with the drive rod, improving the stability of flocculation sedimentation.

This invention provides a purification device for purified water, comprising a pretreatment sedimentation tank, a multi-media filter, an activated carbon filter, and a reverse osmosis device arranged sequentially. The pretreatment sedimentation tank is provided with a lower inlet and an upper outlet. A water treatment device is also provided inside the pretreatment sedimentation tank. The water treatment device includes a filter element and a backwashing mechanism. A gear pump pumps the filtered water in the outlet area through a delivery pipe to a strip box. The water flow sprays out from the opening on the lower side of the strip box and acts on the surface of the filter element. Simultaneously, the strip box rotates radially on a central column, performing a full-area, uniform backwashing of the filter element, flushing the attached impurities back to the inlet area, eliminating the need for an external flushing water source.
