Typically, for a well-designed landfill has avoided groundwater and surface runoff into the landfill, leachate mainly from atmospheric precipitation, surface irrigation, solid waste aqueous gold-plated high recycling and landfill waste decomposition process water, where rainfall is an important factor affecting the amount of leachate generated. For the bottom level and slope no water seepage laying landfill liner, or in the water table below ground construction type landfill or valley-type landfill, groundwater intrusion is an important source of leachate; for not set of high-quality surface water control system landfills, surface runoff may lead to excessive leachate, landfill so as to achieve high results. Electronics Recycling professionals revealed: In today's society, cell phones, computers, air conditioners, refrigerators, copiers, fax machines and other electronic products and appliances, to people's lives has brought great convenience. With the development of technology, replacement of electronic products faster and faster, at the same time, the number of e-waste scrap is also growing. These scrapped electronic waste containing heavy metals and other harmful substances, if not handled properly, it will cause harm to the environment. After years of research, found a make e-waste "back to life" approach. In this way, not only to avoid contamination, but also extract useful components of electronic waste, electronic waste resources, to achieve "turning waste into treasure." The new technology allows electronic waste into resources, "mine" one ton of used computer can be extracted from 660 grams of gold, 1 kg silver, 150 g of copper, nearly two kilograms of precious metals and other resources; 1 ton of old mobile phones can be extracted from 400 grams of gold, 2.3 kg of silver and 172 g of copper and the like. Today, the method for processing electronic waste: waste is fed into the circuit board level crusher, crushed into 1-2 cm of particles; these particles in the secondary crusher again "downsizing" of less than 0.8 mm into a fine powder. Then, they all enter a high-voltage electrostatic separator "Accept assessment", gold recovered by high-voltage electrostatic effects, non-metallic powder is a roller shaft firmly suck, and metal powder were "dumped" from the big forces. Finally, the metal powder was isolated by vacuum distillation of various components of gold, copper, iron and other non-metallic powder can be made into renewable extruded sheet - this way, all of the waste can be "active aging" of the. How effective is treatment? Often gilded recycling companies, mining 1 ton Jinsha can refine gold gilt prices recovered about five grams, according to estimates, powder per ton of scrap computer after the destruction, the gold content is 660 g. Moreover, from one ton of scrap computer can also extract 1 kg of silver, 150 g of copper, nearly two kilograms of rare metals and other resources. From one ton of old mobile phones can be extracted from 400 grams of gold, 2.3 kilograms of silver, 172 g copper.
