AI Technical Summary
Technical Problem
In traditional microbial degradation technologies, the microbial carriers have a small specific surface area and insufficient contact with sludge, resulting in low sludge treatment efficiency and the risk of secondary pollution.
Method used
Microbial-fly ash porous material is used. Fly ash is mixed with sugars and granules, which are then aged with a composite aerobic microbial culture solution to form a porous structure, increase the specific surface area, and improve sludge contact efficiency.
Benefits of technology
It improves sludge treatment efficiency, effectively removes organic pollutants, nitrogen and phosphorus pollutants and heavy metals, reduces costs, avoids secondary pollution, and is suitable for large-scale application.
