Research on Debugging Technology of Active Sand Denitrification System
This paper introduces in detail the debugging technology of active sand denitrification system in the third phase of a sewage plant upgrading project in Guang-dong Province.The purpose of the study is to improve the efficiency of sewage treatment,especially in nitrogen and phosphorus removal.Carbon source dosing,coagulation dosing and denitrification type continuous quicksand filter process were adopted to ensure that the effluent water's quality meets the requirements.It not only discusses the assembly and operation debugging of the system,but also emphasizes the key steps in the operation process,such as filter sand sedimentation velocity monitoring and cleaning water flow velocity debugging.The study shows that rea-sonable debugging and operation can effectively improve the treatment capacity of the system and ensure efficient and stable wastewater treatment.
