Paper Title:
The Technological Research and Application of the Adsorption and Purification of Heavy Metal Chromium in Mining Waste Water Using Microbial Immobilization Technology
  Abstract

The Leptospirillum ferrooxidans which had been selected and cultivated from mine area was applied in treatment of Cr(VI) -containing waste water in the laboratory and real Cr(VI) -containing waste water. The principle of its adsorption process was probed. The results show that the main factors which affect the lead uptake are pH value、ways of pretreatment、contacting time、co-existing ions、Leptospirillum ferrooxidans concentration insolutions,etc.It was able to adsorb Cr(VI) efficiently.After adsorption steps of the treatment, the concentration of heavy metal Cr(VI) in solution met the standard for treating waste water. After adsorption treatment of containing chromium mine wastewater, the concentration of chromium ions reaches the first class of irrigation water quality standards.
