Industry Overview: China's economy has maintained rapid growth, has become the center of world manufacturing and processing industry, electroplating technology plays an important role not only in the traditional industries; play on the high-tech industries, such as modern electronics, microelectronics, communications products manufacturing increasingly large role. Has become an integral part of China's manufacturing industry. China has tens of thousands of electroplating enterprises, mainly concentrated in the Pearl River Delta region base, Wenzhou, Jinhua, Zhejiang Jiaxing area, Kunshan, Suzhou, Wuxi, Shandong coast and northeast coast, Chongqing and surrounding areas. With the growth of the market, our plating technology from different levels have been great strides, but the industry is the existence of small businesses and more, technology updates slow, low management level, pollution and other problems, serious problems with the development of this industry, Many cities electroplating factory forced environmental pressures, have closed, transferred to rural and remote areas of poverty, but this is not a fundamental solution. Electroplating industry itself is not an independent industry, it is inseparable with the local industry, electroplating industry therefore needs to get long-term development in the country, before going to solve the problem of development and environment friendly approach to sustainable development is also plating of people have been looking for a. Water reuse and recycling of resources: 1, the senior electrochemical plating wastewater treatment effluent treatment after one machine to reach the new national standard, can be used in the rinsing process section, and then after a simple concentration treatment can be used in the production of any technology segment, truly zero emissions. At the same time save a lot of municipal tap water fees and charges. 2, do not add chemicals to produce less sludge, most precious metals can reuse, reduce pollution, resulting in benefits. Plating process, wastewater and water sources: the metal plating process is plated onto the surface of the process by electrolysis products, commonly used in plating of nickel, copper, chrome, zinc plating, cadmium plating, lead, silver, tin , gold-plated. Second, the main source of water: 1, plating rinse water. Accounted for about 80%. 2, plating rinse water filtration and waste bath. 3, electroplating workshops "run, run, drip, leak" waste emissions. Third, the hazards of electroplating wastewater: electroplating wastewater on its total volume, such as water, paper, printing and dyeing, chemical, and other industries in the small, narrow surface contamination, but because of extensive electroplating factory point distribution, highly toxic substances contained in waste water species more, the danger is great. Untreated electroplating wastewater discharged into compliance rivers, ponds, into the ground, not only will harm the environment, but also contaminate drinking water and industrial water. Chromium electroplating wastewater containing zinc, copper, cadmium, lead, nickel and other heavy metals and acid, alkali cyanide and other toxic debris great. Some are carcinogenic and toxic substances also cause distortion. Therefore must be dealt with seriously. So as not to cause harm to people. Cracking Searle Introduction: National Plating pollutant emission standards from August 1, 2008 implementation, our company also based on the new standards and existing electroplating wastewater treatment, the independent research of three new processes. 1. Worry discharge process: apply to existing or new chemical precipitation process transformation, electroplating wastewater reuse rate of about 35%. 2. easy to block membrane water reuse process: suitable for chemical precipitation process, have to meet emission standards, further recycling and reuse wastewater, reuse rate can reach 65%. 3. shunt treatment of heavy metal recovery process: for electroplating wastewater diversion collect more standardized, there are more precious metal plating and electroplating wastewater reuse enterprises have higher requirements. Electroplating wastewater reuse rate above 85%.
