Description

Technical Field

[0001] This utility model relates to the field of copper tailings wastewater treatment, and in particular to a copper tailings wastewater treatment device. Background Technology

[0002] The refining and processing of copper ore generates a large amount of wastewater. This wastewater has a distinct blue-green color when discharged, making it easily identifiable. It poses a significant threat to human health and the environment, thus requiring treatment. Current treatment methods involve adding sodium sulfide to the wastewater to reduce copper ions in the wastewater to copper sulfide, causing it to precipitate. This process can also address some heavy metal issues. However, the presence of organic matter in the discharged wastewater still poses a certain degree of harm to the natural environment. Therefore, we have designed a copper tailings wastewater treatment device. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the actual needs, and provide a copper tailings wastewater treatment device, including a sedimentation tank and an organic matter treatment tank; a sodium sulfide injection pipe is provided above the sedimentation tank; one side of the sedimentation tank is connected to the upper side of the organic matter treatment tank through a connecting pipe 4; a biofilm filter element is provided in the organic matter treatment tank; an outlet pipe is provided on the lower side of the organic matter treatment tank; and valves are provided in both the outlet pipe and the connecting pipe.

[0004] The sedimentation tank is equipped with a top plate, and a stirring motor is installed on the top plate. The rotating shaft below the stirring motor extends into the sedimentation tank, and stirring blades are provided on both sides of the rotating shaft.

[0005] The main body of the organic matter treatment tank is a rectangular trough structure. The organic matter treatment tank is provided with stepped support troughs on both sides. The biofilm filter element includes an outer metal frame and a middle biofilm filter. The metal frame is provided with outer eaves on both sides. The biofilm filter element is inserted into the organic matter treatment tank, and its outer eaves are supported on the support troughs.

[0006] One or more biofilm filter cartridges are arranged side by side.

[0007] The organic matter treatment tank has movable grooves on both sides, and limit grooves are provided along the length of the opposite outer sides of the movable grooves. Two rollers are provided in each of the movable grooves on both sides. The rotating shafts of the rollers extend from the limit grooves and are fixed to vertical plates. Support plates are fixed above the two vertical plates. Lifting electric cylinders are provided on both sides of the support plates. The electric cylinder rods below the lifting electric cylinders pass through the support plates and are provided with hooks. Hanging holes are provided on the upper part of the metal frame at positions corresponding to the hooks.

[0008] The beneficial effects of this utility model are as follows:

[0009] This device uses a combination of sedimentation tank and organic matter treatment tank. Sodium sulfide is added to the sedimentation tank to treat heavy metal ions such as copper. The water is then sent to the organic matter treatment tank through pipelines, where the organic matter is treated by a biofilm. The biofilm filter cartridges that need to be replaced periodically are hung up and replaced by hooks on the electric cylinder on the support plate, so that the sewage treatment can be carried out without interruption for a long time, thus speeding up the treatment efficiency.
