The invention relates to a biological floc, a preparation method thereof and application thereof in aquaculture, water purification, industrial water treatment and soil remediation and improvement. The preparation method of the biological floccule comprises the steps of adding a microbial agent into decomposed straw powder, and then sequentially adding nitrobacteria and denitrifying bacteria. The biological floc takes decomposed straw powder as a main body, and main technical indexes of the biological floc reach or are even superior to those of foreign biological flocs of the same type by adding specific microbial agents, nitrobacteria and denitrifying bacteria, and tests prove that the biological floc has a very good purifying effect on river sewage. |
