Shandong is convinced that working with Xi'an Jiaotong University to break through the technical bottleneck and fill the gaps at home and abroad-successfully developed the resource treatment technology of low-concentration heavy metal ion wastewater

Industries such as electroplating, iron and steel, non-ferrous metal smelting, and chemical companies generate a large amount of heavy metal wastewater every year. Since heavy metals cannot be biodegraded, they can only enter the organic matrix through transfer and diffusion, and they are continuously enriched in the organism. When heavy metal pollutants accumulate to a certain limit, they will cause serious harm to water bodies, aquatic plants, aquatic animals and other ecosystems, and may affect human health through the food chain. Therefore, deep purification of such pollutants in water bodies is increasing. People pay more attention.

At present, there are many methods to treat heavy metal wastewater, mainly chemical precipitation method, adsorption method, ion exchange resin method, evaporation concentration method, electrodeposition method, microfiltration, ultrafiltration, nanofiltration, reverse osmosis, electrodialysis, and electrodeionization Technology and other membrane separation technology. Although these processes are effective in treating high-concentration heavy metal wastewater, they are not effective in treating medium and low-concentration heavy metal wastewater. They have problems such as high treatment costs, poor effluent quality, and secondary pollution.

In order to solve this technical problem, the company has joined hands with experts and professors of Xi'an Jiaotong University to conduct research and research, after more than a year of continuous demonstration and experiment. Developed a resource disposal method for low-concentration heavy metal ion wastewater, enriched the low-concentration heavy metal ion wastewater, and then used the electrodeposition process to separate heavy metal ions from the water into solids.

The successful research and development of this technology has been highly recognized by all sectors of society. The National Intellectual Property Office of the State Intellectual Property Office for the invention of this technology has passed the demonstration and entered the substantive examination. The relevant utility model patent has been authorized and issued. At the same time, the technology has been incorporated into Shandong by the Shandong Provincial Department of Industry and Information Technology. The first batch of technological innovation projects in the province, related products have entered the pilot stage, and will soon be put into society to benefit mankind.

In recent years, the company has always listed energy-saving and environmental protection technology research as its top priority for development, adhering to\"Starting from solving customer problems, taking energy saving and environmental protection as our own responsibility\"To make full use of the engineering technology center, key laboratories, and enterprise technology centers, and actively cooperate with experts and professors of Xi’an Jiaotong University to tackle key problems, long-term commitment to cement, electric power, petrochemical, coal chemical, mineral chemical, pharmaceutical chemical, and non-ferrous metal smelting And other industries provide tailor-made energy-saving and environmental protection solutions. I believe that in the future, Shandong is convinced that it can become a positive pioneer in my country's energy conservation and environmental protection, and protect my country's ecological environment.
