Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a multi-series rapid mud filling method. Background Art

[0002] Multi-series rapid sludge replenishment refers to the rapid replenishment of sludge through multiple series of biological pools in the sewage treatment system. The sludge in the biological pool is mainly responsible for the degradation of organic matter in the sewage. The appropriate sludge concentration can ensure the activity and treatment capacity of microorganisms. Through rapid sludge replenishment, the sludge concentration can be adjusted in time to ensure that the sludge in each biological pool is in the best state, thereby improving the overall sewage treatment efficiency; the multi-series biological pool may have insufficient sludge concentration or fluctuations in treatment effect during the treatment process. Rapid sludge replenishment technology can quickly respond to these changes and stabilize the treatment effect by adjusting the amount of sludge replenishment to prevent the decline in treatment capacity; traditional sludge replenishment methods require a long time to complete the addition and uniform distribution of sludge, and multi-series rapid sludge replenishment technology reduces the time of sludge replenishment through efficient sludge replenishment system and pipeline design, and improves the overall treatment cycle of sewage treatment. Therefore, multi-series rapid sludge replenishment is of great significance.
