Analysis on the Operation Capacity of Over-designed Water Volume in Flood Season of Southern Urban Sewage Treatment Plant
Taking a sewage treatment plant in Zengcheng District of Guangzhou as an example,this paper analyzes the operation capacity of over-designed water volume in flood season,including the operation analysis of primary treatment unit,biochemical tank,secondary sedimentation tank,advanced treatment unit and sludge treatment system,as well as the analysis of effluent effect of treatment.The research shows that the maximum treatment capacity in flood season is about 1.5 times of the designed treatment scale without engineering expansion or upgrading;the key links restricting the upper limit of the over-designed water volume treatment capacity of the sewage treatment plant are the primary treatment unit and the secondary sedimentation tank;by adjusting the operation means such as dosing and aeration to adjust the biochemical tank and advanced treatment process,the sewage treatment capacity is strong.
