technical field

The invention belongs to the technical field of sewage treatment devices, and in particular relates to a treatment device for rapidly absorbing sewage.

Background technique

With the increasing industrial activities, a series of outstanding problems such as environmental pollution and ecological damage have been caused. The root cause of these problems is that the pollutants discharged into the environment exceed the self-purification capacity of the environment, the most prominent of which is heavy metal pollution in water. Heavy metals are widely found in industrial wastewater such as electroplating, metal surface treatment, tanning, chemical industry, manufacturing, mining, and battery manufacturing. The continuous accumulation in the body will eventually affect human health, so the removal of heavy metals in the environment has attracted much attention. At present, common methods for removing heavy metals in wastewater, such as adsorption, extraction, ion exchange, electrodialysis, chemical precipitation, etc., have obvious effects, but they are expensive and difficult to use on a large scale.
