英文摘要： At present,the biological flocculation technology in the emerging interdiscipline field of mining biological of great concern. Microbial flocculants research and development of efficient and environmentally friendly, has important practical significance and good application prospect. This project through the bacteria and fungi to class of flocculation effect with the microorganism strains breeding and selection, optimized for microorganism strains with higher flocculating activity and more adaptable. In different types of single-strain flocculation conditions optimization based on experiment,focus on bacteria and bacteria,fungi and fungi,and bacteria and fungi strains collaborative research to strengthen the flocculation effect of coal and flocculation mechanism, access to the best test results, and its key technical parameters of the biological flocculation of coal and so on.The study used homogenization of the experimental design and nonlinear simulation optimization method, to build multi-strains collaborative to flocculation multi-variable mathematical model.Using modern testing techniques such as ultraviolet, infrared spectroscopy and scanning electron microscopy of strains and flocculation structure of matter, the nature of the test analysis.Based on fractal theory, to carry out the biological flocculation
