Description

Technical Field

[0001] The utility model relates to the technical field of electroplating wastewater treatment, in particular to an electroplating wastewater treatment device for reducing secondary pollution. Background Art

[0002] The sources of electroplating wastewater are generally: plated cleaning water, waste plating liquid and other wastewater, including flushing of workshop floors, plate washing water, ventilation equipment condensation water, and various tank liquids and drainage caused by leakage of plating tanks or improper operation and management. There are many harmful substances, so a electroplating wastewater treatment device is needed to reduce secondary pollution.

[0003] According to the description of an electroplating wastewater treatment device disclosed in the patent website (authorization announcement number: CN 215627152U), "an electroplating wastewater treatment device includes a base, a wheel is provided at the bottom of the base, a protection box is provided on the base, a power supply is provided at the inner bottom of the protection box, the top of the protection box is open, and a rectangular mounting pipe is provided at each of the four corners inside the protection box. The utility model provides an electroplating wastewater treatment device, which adds electroplating wastewater to the treatment box through a liquid inlet pipe, so that the electroplating wastewater is fully mixed with small bubbles, and the harmful substances contained in the electroplating wastewater are fully separated from the wastewater. At the same time, the motor and the air inlet pipe are located at the front left side of the treatment box. When the spiral blade rotates, it pushes the electroplating wastewater to rotate in the treatment box, so that the electroplating wastewater is fully in contact with the activated carbon on the adsorption grid, and the activated carbon on the adsorption grid fully adsorbs the harmful substances in the electroplating wastewater. After the adsorption operation is completed, the liquid outlet pipe at the bottom of the box is opened, and the treated electroplating wastewater without harmful substances is discharged from the liquid outlet pipe, thereby completing the adsorption treatment operation of the electroplating wastewater."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, the filter enters the adsorption chamber, and the air intake pipe injects bubbles into the water injection chamber. The injected bubbles are broken by the spiral blades and pushed to the right during the rising process. The broken bubbles are further divided and broken by the filter when passing through the filter to the right, so that the electroplating wastewater and the small bubbles are fully mixed, and the harmful substances contained in the electroplating wastewater are fully separated from the wastewater. However, in actual use, there are many impurities in the electroplating wastewater. When the filter is filtering, the impurities may be too much to block the filter, making it impossible for the wastewater to pass through the filter and contact the activated carbon in the adsorption grid, so that the harmful substances cannot be adsorbed by the activated carbon, causing abnormal treatment of the electroplating wastewater. Secondly, the spraying range of the nozzle is small, and the harmful substances on the adsorption grid cannot be washed off, resulting in residual harmful substances, which is not conducive to the next use. Therefore, it is necessary to improve an electroplating wastewater treatment device that reduces secondary pollution to solve the above problems. Utility Model Content
