[0002] Heavy metal wastewater treatment refers to the process of removing heavy metals from heavy metal wastewater and recycling or rendering them harmless. Heavy metal wastewater is generated in many production processes in industries such as mining, machinery manufacturing, chemical industry, electronics, and instrumentation.

[0003] In the prior art, a patent document with publication number CN217418394U proposes a filtering device for treating heavy metal wastewater, which belongs to the technical field of heavy metal wastewater treatment.

However, there is still a situation where the filter device cannot filter harmful substances during use, which reduces the practicality of the filter device. Utility Model Content
