结合航煤的实际情况,在实验条件下观察温度、pH值、Fe2+和Cl-4个因素的综合作用对微生物生长的影响.采用了正交试验设计,并对实验结果进行科学的统计分析.通过极差和方差分析法分析实验结果得出最优生长条件是温度为35℃、pH值为7、Fe2+的浓度为150 mg/L和Cl-的浓度为1.5 g/L.Fe2+浓度对航煤中微生物的影响比pH值的影响要大,具有一定代表性,为进一步研究微生物的防治提供技术指导.
Combined with the actual situation of jetty, the effects of temperature, pH value, Fe2 + and Cl-4 factors on the growth of microorganism were observed under the experimental conditions.The orthogonal experiment design was adopted and the experimental results were statistically analyzed. The results of range and variance analysis showed that the optimal growth conditions were 35 ℃, pH 7, Fe2 + concentration of 150 mg / L and Cl- concentration of 1.5 g / L. Fe2 + The influence of microorganisms in coal is greater than the influence of pH, and it has some representativeness, which provides technical guidance for further research on the prevention and treatment of microorganisms.
