Abstract
The research cooperation project on a technology to treat well waste water by utilizing biomass has used as the object the well waste water from the north mine in the Wu Shan mine in Jiangxi Province. The research included surveys on properties of the well waste water from the subject mine by means of the site survey, discussions on treatment conditions based on studies in Japan, and discussions on factors for designing a full size facility as a result of pilot plant operation research. The Japanese side has transported to Beijing the bench-scale testing equipment used for the studies in Japan (an oxidation and neutralization testing equipment and a copper recovery testing equipment). In the present follow-up project, supports were provided to the research and development activities performed voluntarily by the Chinese side by using the above bench-scale testing equipment through guiding the tests at the site and supplying consumables. Certain bacteria have capability to oxidize ferrous ions in the mine well waste water into ferric ions. Utilizing these bacteria results in sedimentation of iron oxides in lower pH zones than in the conventional method, making removal of heavy metals from the well waste water possible. As a result, such
