Bio-chemistry Process of Iron and Manganese Recycling in Water-mineral-microbe System

The bio-process of the iron and manganese recycling in the water-mineral-microbe system is analyzed, and the researching trends on solution of environmental pollution problem by use of this process is prospected. The metals recycling in the water-mineral-microbe system is controlled by the recycling and conversion of the iron and manganese ions and oxides under the microbes catalysing, and is coupled with the recycling process of carbon, nitrogen, phosphate and sulfur. The superficial pollution problem of the water body can be solved by means of strengthening the recycling of the water-mineral-microbe system to degrade the organic pollutes through the bio-process between the superfical water and sediments. The muti-scale pollution of spot, zone, territory and whole earth can be prospected, controlled, perpetualled and remedied by the help of the simulation of the complicated factors and strengthening means.
