Description

Technical Field

[0001] This utility model relates to the field of electroplating wastewater treatment technology, and in particular to an electroplating wastewater treatment tank. Background Technology

[0002] Electroplating wastewater treatment is an indispensable part of industrial production, especially in industries such as metal processing and electronics manufacturing. The wastewater generated by electroplating processes contains large amounts of heavy metal ions and other harmful substances, and direct discharge can cause serious environmental pollution. Therefore, developing efficient electroplating wastewater treatment technologies is not only necessary for environmental protection but also crucial for the sustainable development of enterprises.

[0003] Existing methods for treating electroplating wastewater mainly include physical, chemical, and biological methods. Physical methods primarily remove suspended solids and some heavy metals from wastewater through filtration and sedimentation; chemical methods involve adding chemical agents to cause harmful substances in the wastewater to react and generate easily separable solids or gases; biological methods utilize the metabolic activity of microorganisms to degrade organic matter in the wastewater.

[0004] These methods each have their own characteristics and are often used in combination in practical applications to achieve the best treatment results. However, existing electroplating wastewater treatment systems have some shortcomings, especially in the difficulty of effectively removing multiple pollutants in the wastewater within the same treatment unit, leading to low treatment efficiency. Therefore, there is an urgent need for a new technology that can efficiently and stably treat electroplating wastewater. Utility Model Content

[0005] This application provides an electroplating wastewater treatment tank, which facilitates efficient and stable treatment of electroplating wastewater.

[0006] This application provides an electroplating wastewater treatment tank, which adopts the following technical solution:

A sedimentation chamber is provided inside the tank body, a filter is provided on one side of the sedimentation chamber, a reaction chamber is provided on the side of the filter away from the sedimentation chamber, a purification chamber is provided on the side of the reaction chamber away from the filter, and a drain pipe is provided on the side of the purification chamber away from the reaction chamber.

[0008] By adopting the above technical solution, this utility model designs an electroplating wastewater treatment tank. During use, the wastewater generated from electroplating is introduced into a sedimentation chamber within the tank. The sedimentation chamber allows for the initial separation of large particulate impurities from the wastewater. The settled wastewater then enters a filter for further filtration, removing suspended solids and fine particles to ensure water purity. Next, it enters a reaction chamber for chemical reaction, accelerating the decomposition and removal of pollutants. Finally, the reacted wastewater enters a purification chamber for further purification. After purification, it is discharged through a drain pipe for collection. This treatment tank treats electroplating wastewater through a series of operations including sedimentation, filtration, chemical reaction, and purification, enabling efficient and stable treatment of the wastewater.

[0009] Preferably, the filter is a multi-stage filter, including at least two stages of filter screens with different pore sizes.

A cover plate is installed on the top of the reaction chamber, which is detachably connected to the top of the reaction chamber to provide a sealed environment for the chemical reaction within the chamber.

[0015] Preferably, a flow meter is installed in the reaction chamber to monitor the change in liquid volume within the reaction chamber and to determine the reaction status within the reaction chamber based on the volume change.

[0016] By adopting the above technical solution, the flow meter can monitor the changes in liquid volume in the reaction chamber in real time during use, thereby accurately judging the dynamic changes in the reaction process and ensuring the stability and controllability of the reaction process.

[0017] Preferably, a second water inlet pipe is provided at one end of the purification chamber near the reaction chamber, and the second water inlet pipe is connected to one side of the reaction chamber. The purification chamber is equipped with an activated carbon adsorption layer for removing trace organic matter, and an ultraviolet lamp is also provided in the purification chamber for disinfecting the treated wastewater.

[0018] By adopting the above technical solution, the second inlet pipe is connected to one side of the reaction chamber during operation, allowing the wastewater after the reaction to smoothly enter the purification chamber, thus improving the continuity and efficiency of the system. The activated carbon adsorption layer effectively removes trace organic matter from the wastewater, improving the water purification effect. Ultraviolet lamps disinfect the treated wastewater, ensuring that the discharged water meets safety standards.

[0019] Preferably, a water quality monitor is installed inside the drain pipe, the water quality monitor is connected to a terminal device, and the water quality monitoring information is transmitted to the terminal device. A switch valve is installed on the drain pipe.

[0020] By adopting the above technical solution, the water quality monitor installed inside the drain pipe monitors the water quality in real time and transmits the data to the terminal equipment, facilitating remote monitoring and management. The on / off valve on the drain pipe can control the discharge process, ensuring the safety and controllability of the system operation.

[0021] Preferably, the inner walls of the sedimentation chamber, filter, reaction chamber, and purification chamber are coated with an anti-corrosion coating to prevent corrosion by wastewater.

[0022] By adopting the above technical solution, the anti-corrosion coating can effectively protect the inner walls of the sedimentation chamber, filter, reaction chamber, and purification chamber from the erosion of wastewater during use, extend the service life of the equipment, and ensure long-term stable operation.

[0023] Preferably, the first water inlet pipe, the second water inlet pipe, the first water outlet pipe, and the drain pipe are all equipped with switch valves.
