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∶〖KG-*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。

Abstract: 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∶〖KG-*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%.
