[0002] Copper, as a material with excellent electrical conductivity and ductility, has a wide range of applications in the fields of electronic components and the like. In the process of manufacturing copper-containing components (such as yellow light etching, electroplating, etc.), a large amount of copper-containing wastewater is generated, which seriously threatens the environment and water resource security. The existing treatment of copper-containing wastewater mainly includes precipitation method, replacement method, membrane filtration method, etc. Among them, the precipitation method mainly uses excessive sulfide ions for treatment, which is easy to cause secondary pollution of water bodies.

[0021] In the embodiment of the present utility model, the wastewater filter core device mainly includes the following four major components: The first part is the assembly part. It mainly includes the flange 2 and fastening screws. The flange 2 is installed on the filter body 1 through the fastening screws, and a conduit is connected to the end of the flange 2.

In this embodiment, the function of the backwashing device is to remove the impurities trapped in the filter element, so that the filter element can restore its filtering ability in a short time. Specifically, the primary backwashing mechanism acts on the impurity filter element 4 to reduce the suspended impurities on the surface of the impurity filter element 4 by combining water flow flushing and air flushing, and the flushing sewage flows out from the sewage discharge port below. The secondary backwashing mechanism acts on the organic matter filter element 5, and also quickly removes pollutants by combining water flow and air flushing.
