Improvement of Wastewater Treatment Efficiency and deodorization by Side-stream Humus Soil Activated Sludge process
Abstract: In humus soil activated sludge process the natural soil growing conditions were simulated. The soil microorganism culture system was appended to the traditional activated sludge system and the soil microorganisms with special functions were returned to the different positions of activated sludge process after they were enriched and activated. The project results showed that in the process nitrogen and phosphorus removal effects were enhanced, the sludge dehydration property was improved greatly, and the elimination of malodor was more important.
