煤炭生物絮凝絮体分形试验研究.

A large number of chemical product flocculants can cause serious pollution to environment. Bacillus subtilis was used as coal bio-flocculating agent to produce bacteria in this study，which has good flocculation effect to coal. Subsequently，the coal biological flocculation experiment and floc fractal study was carried out. Based on the acquisition and analysis of biological flocculation flocs microscopic image，the floc fractal dimension was calculated using flocculation body projection area and the maximum length of flocculation. The study found that the Bacillus subtilis dosage and floc fractal dimension and the coal slime water light transmittance are significantly correlated.The study results show that if the fractal dimension of flocculation body is as main control index，the Bacillus subtilis quantitative control can be achieved.It also more objectively reflects the flocculation sedimentation process of coal slime water.
