Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, and specifically relates to an electroplating waste liquid circulating filtering device. Background Technique

[0002] The electroplating wastewater circulating filtering device is a device used for electroplating wastewater treatment. It can filter out harmful substances in the wastewater and realize the recycling of the wastewater. This device usually includes a regulating tank, a coagulation sedimentation tank, an intermediate water tank, a quartz sand filter, a clear water tank, etc. The electroplating wastewater first passes through the regulating tank to adjust the water quality and water volume, and then adjusts the PH to an alkaline condition to make the wastewater easier to precipitate in the coagulation sedimentation tank. Various heavy metal ions form hydroxide precipitates, and PAC and PAM are added in the coagulation sedimentation tank, and mechanical stirring is used to assist in capturing the heavy metal precipitates and removing the organic matter in the wastewater. After that, the wastewater passes through the intermediate water tank to adjust the water quality and water volume again, and then is pumped into the quartz sand filter by a pump. After passing through the quartz sand filter layer, fine particles, colloids and part of the organic matter are intercepted, and the water quality is further purified;

[0003] Since the pore size of the quartz sand filter plate is relatively small, it is easy to be blocked when there are many impurities in the sewage, and the quartz sand needs to be cleaned and replaced regularly. The common replacement method is to manually disassemble the filtering device, then loosen the screws at the filter plate, and remove the filter plate inside it. This method has low replacement efficiency. Content of the Utility Model
