The Ministry of Environmental Protection recently issued the “Guidelines for the Best Available Techniques for Electroplating Pollution Prevention and Control (Trial)”, which provides technical basis and guidance for the industry to improve its technological level, carry out pollution control and related environmental supervision. The technical guide first analyzes the treatment technology of process pollution prevention, wastewater treatment, spray tower electroplating waste gas, dust removal, wastewater sludge treatment and disposal, and points out the advantages and disadvantages of various main treatment technologies and their scope of application. On this basis, various best available technology combinations were put forward, and its process parameters, pollutant reduction and emission, economic applicability, etc. were clarified around the technology, and as many as 44 technical application considerations were also proposed, which has strong Guidance. The pollution produced by the electroplating process includes water pollution, air pollution, solid waste pollution and noise pollution, including water pollution (mainly Read more

As one of the four basic manufacturing processes, electroplating is widely used in various industries, such as high-end electronics, aviation, aerospace, energy, nuclear industry, low-end daily hardware, auto parts, stationery products, etc. Replaced service industries. According to incomplete statistics, in 2009, the number of electroplating enterprises (enterprises above designated size) in my country totaled 15,000, with more than 5,000 production lines and a production capacity of 250 to 300 million square meters of electroplating area. In recent years, with the remediation of heavily polluting enterprises by local governments, the number of electroplating enterprises has been on a decreasing trend. In 2008, the Ministry of Environmental Protection promulgated the “Emission Standards for Electroplating Pollutants” (GB21900-2008). The promulgation of the standards provides a basis for the management of key industries and key pollution sources. What problems does the new emission standard encounter? Need to find a balance between compliance with investment and Read more

In terms of the total amount of electroplating wastewater, such as papermaking, printing and dyeing, chemicals, pesticides, etc., the amount of water is small, and the pollution surface is narrow. However, due to the wide distribution of electroplating plants, there are many types of highly toxic substances in the wastewater, which is very harmful. Untreated electroplating wastewater discharges 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, and nickel, as well as highly toxic impurities such as acid and alkali cyanide. Some are also highly toxic substances that cause cancer and distortion. Therefore, they must be dealt with carefully to avoid harm to people. (1) Typical process flow (2) Principle of heavy metal removal Generally, heavy metal ion removers can be used Read more

In recent years, the sales of smart terminals have achieved rapid growth, but experts suggest that this growth rate will gradually slow down. The glorious thing is that the electronic accessories market, which is dominated by smart terminals, has gradually gained momentum, continuing the prosperous scene of the electronic market. Brands and channels, as the two legs of market sales, have always been the focus of electronic product manufacturers. Offline channels are not without opportunities. Entering large shopping malls and offline stores that emphasize experience will become the main battlefield for high-end brand electronic products. Electronic product brand Ten-year cycle of domestic brands, innovation and upgrading. The market share of electronic products in my country has increased this year, especially in the smart terminal market. At present, domestic brands have entered the high-end smartphone market. Relevant data shows that in the first half of 2013, domestic brand smartphone sales reached Read more
