摘　　要：分析水-矿-微生物系统中铁锰循环的生化过程,提出利用该过程解决环境污染问题的研究方向。微生物催化铁锰离子及其氧化物的循环转化主导着水-矿-微生物系统中的金属循环,还与碳、氮、磷、硫循环过程耦合。强化水-矿-微生物系统中的循环通量,利用表层水体和沉积物界面的生化过程降解有机污染物,固定重金属,解决大规模面源污染。模拟自然水体多因素耦合过程及强化途径,达到对对场地规模、区域规模、流域规模乃至全球规模水环境的预测、控制、干预和治理。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 bioprocess 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.
