Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to an aeration device for treating electroplating wastewater. Background Technology

[0002] Wastewater refers to the water discharged during residential activities and rainwater. It includes domestic sewage and industrial wastewater. For example, electroplating processes generate electroplating wastewater. To reduce the environmental damage caused by electroplating wastewater, it needs to be purified before discharge. Aeration is one method of treating electroplating wastewater. Water treatment aeration devices are used in this process. The working principle of these devices is to transfer oxygen from the air to the wastewater to supply the oxygen needed for aerobic biological metabolism, while simultaneously thoroughly mixing the wastewater to achieve biological treatment. However, in practical use, the following shortcomings still exist:

[0003] 1. In the process of using a water treatment aeration device to treat electroplating wastewater, air is directly introduced into the wastewater, so that the aerobic organisms in the electroplating wastewater come into contact with oxygen to react and treat the electroplating wastewater. This requires a drive motor to drive the stirring components to stir and mix the electroplating wastewater to prevent the sedimentation of impurities in the electroplating wastewater. More efficient treatment of electroplating wastewater will increase electricity consumption and energy consumption.

[0004] 2. After the electroplating wastewater is treated using a water treatment aeration device, the water is discharged directly. However, during the aeration process of electroplating wastewater, some untreated wastewater is inevitably discharged directly. Therefore, it is necessary to perform multiple aeration treatments on the electroplating wastewater to improve the treatment quality.

[0005] To address these issues, we provide an aeration device for treating electroplating wastewater. Utility Model Content

[0006] The purpose of this utility model is to provide an aeration device for electroplating wastewater treatment. By setting an inlet component, the electroplating wastewater can fully contact the gas, eliminating the need for a drive motor and reducing power consumption. Furthermore, by setting a circulation component, the electroplating wastewater can be aerated multiple times, which helps to improve the treatment quality of the electroplating wastewater and solves the technical problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to an aeration device for treating electroplating wastewater, comprising a treatment tank, an inlet assembly on the treatment tank, the inlet assembly including a water collection box located in the upper part of the treatment tank, an inlet pipe connected and fixed at the center of the upper surface of the water collection box, and a rectangular array of nozzles connected and fixed at the lower surface of the water collection box; the inlet assembly also includes an air collection box located at the center of the inner side wall of the treatment tank, an air inlet pipe connected and fixed at the side wall of the air collection box located outside the treatment tank, and air holes in a rectangular array on the side wall of the air collection box facing the interior of the treatment tank; the treatment tank also includes a circulation assembly, comprising a water pump installed on the side wall of the treatment tank, the lower end of a return pipe connected to the inlet of the water pump is connected to the interior of the treatment tank, the upper end of a connecting pipe connected to the outlet of the water pump is connected to the inlet pipe, and a filter plate connected to the lower part of the inner part of the treatment tank is located below the return pipe.

[0009] The present invention is further configured such that the bottom of the treatment box has symmetrically fixed water guide plates, the center of the lower surface of the treatment box has a connected water outlet pipe, and the four corners of the lower surface of the treatment box are equipped with self-locking casters.

[0010] The present invention is further configured such that the upper part of the side wall of the processing box has a through groove, the inside of the through groove has an embedded mesh plate, the position of the shielding frame installed on the upper part of the side wall of the processing box corresponds to the position of the through groove, and the side wall of the shielding frame has a communicating air outlet pipe.

[0011] The present invention is further configured such that a cover plate is provided on the upper surface of the treatment box, and screws are fixedly connected to the four corners of the upper surface of the treatment box. The upper ends of the screws penetrate the corners of the cover plate, and locking nuts connected to the circumferential threads of the screws abut against the cover plate.
