AI Technical Summary
The problem of floating sludge in the secondary sedimentation tank caused by DCM control agents in sulfate pulping cannot be effectively solved by existing technologies, resulting in reduced biochemical treatment efficiency and increased environmental pollution risks.
By precisely raising dissolved oxygen, controlling high temperature, regulating pH within a narrow range, and through the synergistic effect of fusion proteins, the pathogenic chain between DCM control agents and filamentous bacteria is broken, the microbial community structure is reshaped, and the fusion protein is used to disrupt the foam skeleton and reduce floating sludge.
It has achieved long-term and stable elimination of floating sludge in the secondary sedimentation tank, restored the efficiency of the biochemical system, reduced operating costs, avoided the side effects of chemical agents, and verified significant results.
