The operation of hot-dip galvanizing in China is very good, and the safety protection of processing and processing has been significantly improved. Electroplating is an important technology in many product processing. However, it is inevitable that it will not be in place during processing. The generated wastewater should be safely disposed of to avoid environmental damage. So how do galvanizing plants and other wastewater treatment? What are the requirements?

What are the methods commonly used in galvanizing plants to treat wastewater?

Galvanizing plants  have a lot of attention in wastewater treatment. In order to ensure the efficiency of wastewater treatment, there are flexible requirements in terms of methods. From the more common methods nowadays, the first method is to use chemical methods, including precipitation method, oxidation method, reduction method and medium law. Different processing methods are considered according to different processing conditions. So what is the effect of these methods?

Precipitation method is a common form of treatment in galvanizing plants . It can effectively separate the substance, neutralize it in the wastewater of heavy metal through chemical form, and separate the precipitation treatment with special chemical substances, so that the heavy metal can be separated by precipitation. , the operation is relatively easy and simple;

The oxidation method is treated in the form of an oxidant, which can isolate and isolate toxic and non-toxic substances, and the safety is also very good. The chemical reduction method is for wastewater treatment, adding special sediment materials, effectively distinguishing, and reducing secondary pollution. .

There are many ways in whichgalvanizing plants can be used in the treatment of wastewater, and there are different considerations for different wastewater conditions. In the actual processing, we must first understand, combined with the needs of different treatments, to ensure the safety effect, to avoid environmental pollution.
