摘　　要：研究利用嗜酸氧化亚铁硫杆菌(At.f菌)和嗜酸氧化硫硫杆菌(At.t菌)的协同作用从鄂西鲕状高磷赤铁矿中脱磷的主要影响因素。研究结果表明,At.t菌与At.f菌按照接种量为2∶1混合后,其脱磷率达到了88.7%,同时在不同矿浆初始pH值和矿浆浓度的试验条件下发现,在pH=1.8～2.5条件下,细菌脱磷能力较强,而矿浆浓度超过5%时对细菌脱磷具有明显抑制作用。The main factors of affecting the removal of phosphorus for high phosphorus oolitic hematite ore by the synergistic effect of Acidithiobacillus thiooxidans（At.t） and Acidithiobacillus ferrooxidans（At.f） were studied.The results showed that when At.t was mixed with At.f at a ratio of 2∶1,the dephosphorization rate can reach 88.7%.Experimental study on the influence of the initial pH and pulp concentration indicated that in the pH range of 1.8～2.5,the bacterial dephosphorization level was high,whereas,the effect of bio-dephosphorization is depressed with the pulp concentration of above 5%.
