| titleOfInvention | Biological reduction treatment technology for expanded sludge |
| abstract | The invention belongs to the field of environmental pollution treatment, and particularly relates to a biological reduction treatment technology for expanded sludge. The specific technical scheme is as follows: a complex microbial flora comprising at least in combination: autotrophic microorganisms are leptospira, mixotrophic microorganisms are sulfobacillus and heterotrophic acidophilic microorganisms. Mixing the complex microbial flora with FeSO 4 Inoculating the sludge and the expanded sludge to be treated together, and carrying out aeration treatment until the pH value of the sludge liquid is 2-3, thus finishing the treatment. According to the invention, a specific culture medium is not required to be prepared for each microorganism independently, so that the culture cost is low; acid is not needed to be added before the reaction to adjust the pH value; no additional sulfur powder is needed. The microorganisms in the composite microbial flora provided by the invention can cooperatively grow, and the composite microbial flora has strong adaptability to sludge and fast growth; the operation is simple and convenient, and the dewatering and decrement effects on the expanded sludge are obvious. |
