[0002] Electroplating wastewater contains harmful substances such as heavy metal ions and acids / alkalis, posing a serious threat to the environment and human health. Multi-stage purification and reuse equipment can effectively remove or reduce these harmful substances, ensuring the wastewater meets national and local discharge standards, thereby reducing harm to soil, water sources, and ecosystems. Through multi-stage purification, useful substances in electroplating wastewater can be recycled and reused, significantly improving water resource utilization efficiency. This not only reduces the consumption of fresh water but also helps alleviate global water resource pressures. Furthermore, wastewater reuse responds to the call for water conservation, achieving the rational and effective use of water resources.

[0003] For example, the multi-stage purification treatment equipment for industrial metal wastewater disclosed in the authorization announcement number CN119059694A includes a purification chamber and a screening chamber connected to the bottom of the purification chamber, and a reaction chamber connected to the lower end of the screening chamber. The upper end of the purification chamber is connected to a water inlet, and the front end of the reaction chamber is connected to a drain valve.

[0004] Although it achieves the effect of preventing water leakage, it can be installed and removed with magnets for easy cleaning by staff. It can prevent the filter screen from clogging and the bottom of the funnel from clogging. It can achieve the effect of vibration and tapping, and can quickly proceed to the next step. It is easy for staff to use and can automatically add medicine without the need for staff to add medicine manually.

It is not easy to easily scrape and discharge large particles of dirt filtered out, which affects the convenience of cleaning the filtered dirt. It is not easy to do a thorough mixing of chemicals to treat electroplating wastewater. It is not easy to treat electroplating wastewater by combining physical and chemical methods, which affects the purification quality and efficiency of multi-stage wastewater purification and reuse equipment.

[0016] (1) When using a multi-stage purification and reuse equipment for electroplating wastewater, the electroplating wastewater is poured into the filter housing through the top cover. The wastewater flows into the mixing tank through the baffles, while the dirt remains on the surface of the baffles. A servo motor drives the rotating shaft to rotate, which in turn drives the scraper to rotate between the baffles. This causes the scraper to move the dirt between the baffles to the surface of the brush cylinder. A stepper motor drives the support shaft to rotate, which in turn drives the brush cylinder to rotate.

The wastewater flows to the bottom of the mixing tank. When the second solenoid valve is opened, the wastewater, supported by the mixing tank, flows through the second solenoid valve and the outlet pipe to the first filter for purification. After the first filter is purified, the water flows from the second hose into the second filter for further purification. This facilitates multi-stage purification and enables the wastewater multi-stage purification and reuse equipment to perform convenient multi-stage purification. It also facilitates the easy scraping and discharge of large particles of dirt from the filter, improving the convenience of cleaning the filter dirt and enhancing the purification quality and efficiency of the wastewater multi-stage purification and reuse equipment.

[0017] (2) When it is necessary to introduce reactants such as activated carbon, the first solenoid valve is opened. The reactants flow into the interior of the mixing tank through the feed pipe and react with the wastewater. The power motor drives the rotating shaft to rotate, and the rotating shaft drives the stirring blade to rotate and stir, so that the wastewater and reactants react fully.

The servo motor 12 drives the rotating shaft 13 to rotate, which in turn drives the scraper 14 to rotate between the baffles 15. This causes the scraper 14 to move the dirt between the baffles 15 to the surface of the brush cylinder 18. The stepper motor 16 drives the support shaft 17 to rotate, which in turn drives the brush cylinder 18 to rotate. This causes the brush cylinder 18 to remove the dirt from the surface of the scraper 14 and collect it in the storage box 4 for unified treatment. The wastewater finally flows to the bottom of the mixing tank 2. The second... Supported by the mixing tank 2, the solenoid valve 11 allows wastewater to flow through the second solenoid valve 11, the outlet pipe 6, and the first hose 22 to the first filter 7 for purification. After the first filter 7 completes purification, the water flows through the second hose 23 into the second filter 8 for further purification, facilitating multi-stage purification.
