Supporting technology for green treatment of metal hazardous waste/solid waste

On August 15, the Institute of Process Engineering of the Chinese Academy of Sciences announced that the institute cooperated with Shandong Hengyuan Recycling Technology C.

This technology realizes the simultaneous and stable solidification of multiple heavy metals in hazardous waste/solid waste by developing a new type of glass-ceramic, with low dissolution rate of heavy metals and strong compatibilit.

According to reports, the annual output of China's industrial hazardous waste exceeds 100 million tons, of which heavy metal hazardous waste accounts for about 1/3, which is very harmful to soil, water, plants and human bod.

In response to the above problems, the R&D team follows the innovative idea of ​​"deep harmless disposal and high-quality utilization of heavy metal hazardous waste/solid waste", and has developed a new vitrification system for heavy metal hazardous waste/solid waste and a new glass-forming technolog.

The leaching concentration of typical heavy metals (chromium, lead, manganese, nickel, et.

The implementation of this new technology is important for promoting the transformation of heavy metal hazardous waste/solid waste from "harmless disposal" to "harmless in-depth disposal, collaborative resource recycling and high-quality recycling", as well as new energy, non-ferrous metallurgy, waste incineration and other industrie.
