Biological treatment of electroplating wastewater

Electric galvanized pollution composition and complex, the main sewage before from galvanized products processing, clean up the surface of galvanized layer after the sewage, and electricity galvanized waste liquid produced in the process of produce, because these are the produced liquid chromium, copper, nickel, zinc and other heavy metals pollution, therefore, if you don't have strict processing will emissions, it  It will have a terrible impact on the environment.

Galvanized sewage treatment, due to people's reform and innovation, has derived a variety of treatment forms of galvanized wastewater commonly used treatment process: grid + regulating pool + chromium reduction pool + coagulation reaction pool + sedimentation pool + filtration + clear water pool.

In addition, let's look at the treatment of heavy metals in wastewater

Heavy metal wastewater treatment method can be divided into two categories, one is in dissolved state of heavy metal in the waste water into insoluble compounds or elements of heavy metals by precipitation and floatation removal from waste water, can be used neutralization precipitation, sulfide precipitation, floatation separation method, electrodeposition, ion flotation or electrolytic float, diaphragm electrolysis, etc;  Second, the heavy metals in the wastewater can be concentrated and separated without changing their chemical morphology. Reverse osmosis, electrodialysis, evaporation and ion exchange can be applied.
