Improvement of Wastewater Treatment Efficiency and Deodorization by Side-Stream Humus Soil Activated Sludge Process
In wastewater treatment system, the humus soil activated sludge process is to culture microorganisms by setting the natural humus soil composite mineral filter to simulate natural soil growing conditions. After enriched and activated in the cultivation tank, the microorganisms with specific functions return to different position of activated sludge process and achieve enhanced operational performance. The project results showed the process could enhance the removal of nitrogen and phosphorus, reduce sludge production, improve sludge dewatering property and achieve odor elimination.
