Electroplating enterprises in the wastewater treatment process will produce a gilded electroplating sludge recycling, due to the plating process, plating types, different wastewater treatment processes vary, sludge composition is more complex. Electroplating sludge handled properly, it will seriously pollute the environment. Meanwhile electroplating sludge containing metals can be recycled, such as copper, nickel, chromium, iron, and zinc. The content of heavy metals in the sludge is much higher than those of some heavy metal content in the ore, with a high value in use. Even less electroplating sludge metal content can also be enriched. Recycling at home and abroad using different methods zinc, chromium, copper and nickel and other metals. According to different ways of electroplating wastewater treatment, electroplating sludge can be divided into sub-quality sludge and mixed sludge into two categories: the former is the different kinds of electroplating wastewater were treated electroplating sludge formed in Hong Kong gilded recovery, such as those containing chromium sludge, copper sludge, sludge containing nickel and zinc sludge, quality of sludge in electroplating wastewater treatment process can extract metals, reduce sludge production; latter is mixing different types of electroplating wastewater processed together to form the electroplating sludge. Depending on electroplating wastewater treatment process or condition, chromium electroplating sludge is divided into non-chromium sludge and sludge two kinds: the former things, in addition to chromium iron, zinc hydroxide, nickel and copper and other metals. From environmental hazards see Guangzhou gilded recycling, waste composition reported computer, only monitors and circuit boards, recycling disposal requires high technology, improper recycling will cause environmental pollution. However, because 90% of copper, aluminum, steel, plastic or the like representing the computer. The recovery of these materials, and if the sorting is to manually disassemble, does not involve a chemical process, not only does not cause environmental pollution, and high recovery rate. Referring to the practice in developed countries, the best option is to scrap computer to computer recycling center. Follow the principle of "first use Macau gilded recycling, reuse dismantling", that is the first to maintain the basic functions of an old computer, you can by inspection, cleaning, maintenance, etc. simply put it into a secondary consumption, that can not be directly used, you can dismantling recycling of value in a variety of electronic components, and finally take the mechanical, physical, chemical raw materials recycling methods. That is recovered first level is reused whole or parts; second level is not split, plastic, metal, glass categorized by parts; finally melting.
