Description

Technical Field

[0001] The utility model relates to the field of wastewater treatment, in particular to a treatment pool for electroplating wastewater. Background Art

[0002] At present, the Chinese utility model with the announcement number CN215626852U discloses an electroplating wastewater treatment pool with a dosing device, including an electroplating wastewater treatment pool and a dosing device, wherein the dosing device is fixedly installed above the inner center of the electroplating wastewater treatment pool, an adjusting device is fixedly installed inside the dosing device, a dosing rack is slidably installed at the inner bottom end of the adjusting device, a limited frame is fixedly installed inside the adjusting device, a driving motor is fixedly installed at the top center of the limited frame, and a threaded rod is rotatably connected to the bottom center of the driving motor. The utility model can spray the liquid medicine in a vortex-type dosing pipe, and can evenly add liquid medicine to the inside of the electroplating wastewater treatment pool, improve the reaction rate and degree of wastewater and liquid medicine, and at the same time, adjust the height of the vortex-type dosing pipe inside the electroplating wastewater treatment pool, so that the vortex-type dosing pipe can be convenient for dosing the inside of the electroplating wastewater treatment pool to prevent the liquid medicine from being blown away by the wind during the spraying process.

[0003] The existing treatment pools have low reaction efficiency. Generally, a stirring mechanism is installed inside the treatment pool to stir the reagents and wastewater to speed up the reaction. However, the stirring direction of the stirring mechanism is fixed, and it is difficult to quickly mix them evenly, which increases the reaction time and affects the reaction efficiency. It also does not have the function of quantitative dosing. Generally, the treatment pools are added based on the experience of the staff. When adding drugs, if too much is added, it will cause waste. If too little is added, it will increase the workload. The amount of drugs added is difficult to control and is inconvenient to use. In order to solve the above-mentioned problems, we propose a treatment pool for electroplating wastewater. Utility Model Content
