my country's economy has continued to grow rapidly and has become the center of the world's manufacturing and processing industries. Electroplating technology not only plays an important role in traditional industries; big effect. It has become an indispensable part of my country's manufacturing industry.

    There are tens of thousands of electroplating enterprises in my country, and the bases are mainly concentrated in the Pearl River Delta region, Wenzhou, Jinhua, Jiaxing in Zhejiang, Kunshan, Suzhou, Wuxi in Jiangsu, Shandong coastal and northeastern coastal areas, Chongqing and surrounding areas.

    With the growth of the market, my country's electroplating technology has made great progress at different levels. However, there are many problems in this industry, such as small and many enterprises, slow technology update, low management level, and large pollution, which seriously plague the development of this industry. Due to environmental pressure, many electroplating plants in big cities have been closed and moved to rural and poor marginal areas, but this is not a fundamental solution. The electroplating industry itself is not an independent industry. It is inseparable from the local industry. Therefore, the electroplating industry needs to develop for a long time in China. The premise of development must be solved in a way that is friendly to the environment. Sustainable development is also what electroplating people have been seeking. of.

 

In terms of the total amount of electroplating wastewater, such as papermaking, printing and dyeing, chemical industry, and other industries, the amount of water is small, and the pollution area is narrow. However, due to the wide distribution of electroplating plants, the wastewater contains many types of highly toxic substances, and its harmfulness is very high. big. Electroplating wastewater that has not been treated up to the standard is discharged into rivers and ponds and seeps into the ground, which will not only harm the environment, but also pollute drinking water and industrial water. Electroplating wastewater contains heavy metal ions such as chromium zinc, copper, cadmium, lead, nickel and other highly toxic impurities such as acid and alkali cyanide. Some are also carcinogenic and teratogenic highly toxic substances. Therefore, it must be dealt with seriously. so as not to cause harm to people.
