Electro -plating, steel, non -ferrous metal smelting and chemical companies produce a large amount of heavy metal wastewater every year. Because heavy metals cannot be degraded by biology, they can only enter the organic substrate through the form of transfers and diffusion, and are constantly enriching in organic bodies. When heavy metal pollutants accumulate a certain limit, it will cause serious harm to ecosystems such as water bodies, aquatic plants, aquatic animals, and may affect human health through the food chain. Therefore The more people pay attention to people.
At present, there are many ways to deal with heavy metal wastewater, mainly including chemical precipitation, adsorption method, ion exchange resin method, evaporation concentration method, electrical sinking method, and micro filter, nathe filtration, reverse osmosis, electrodiacrete, electrocomputer ion ion Technology and other membrane separation technology. Although these processes are better to deal with high -concentration heavy metal wastewater, the effect of low -concentration heavy metal wastewater is not effective in treating low -concentration heavy metal wastewater. There are problems such as high treatment costs, poor water outlets, and prone to secondary pollution.
In order to solve this technical problem, the company joined hands with the experts and professors of Xi'an Jiaotong University to conduct research and research, and after more than a year of continuous demonstration experiments. A resource disposal method for low -concentration heavy metal ion wastewater is developed to enrich the low -concentration heavy metal ion wastewater, and then uses the electrical deposition process to precipitate heavy metal ions from the water as solid.
The successful research and development of this technology has been highly recognized by all sectors of the society. The National Intellectual Property Office of this technology invention has demonstrated and passed to enter the substantial review. The relevant practical new patent has authorized to issue a certificate. At the same time The first batch of technological innovation projects in the province, related products have entered the middle of the trial, and will soon be put into the society to benefit humans.
In recent years, the company has always listed energy conservation and environmental protection technology as the primary task of development, adhering to"The starting point is to solve the customer's problem, and the energy conservation and environmental protection is its own responsibility"The concept, make full use of the engineering technology center, key laboratory and enterprise technology center, actively jointly assault with experts from Xi'an Jiaotong University, and have long been committed to the smelting Wuling in the industry to provide a tactical and energy -saving and environmental protection solution. I believe that in the future, Shandong is convinced that it can become the pioneer of energy conservation and environmental protection in China and escort my country's ecological environment.
