Title: Design of Upgrading and Retrofitting Process in Xuehang WWTP in Lianshui County
Abstract: The general design capacity of Xuehang WWTP in Lianshui County is 1×104 m3/d.The design capacity of the first-phase project is 2 500 m3/d.The effluent quality of the original process could not reach the first level criteria specified in Jiangsu Provincial Discharge Standard of Main Water Pollutants for Chemical Industry(DB 32/939-2006),so the combined process of air flotation,internal circulation microelectrolysis,Fenton reagent,coagulation sedimentation,A2/O process,activated carbon filter and chlorine dioxide disinfection is adopted now.The general situation,process flow and design parameters of the upgrading and retrofitting project are presented.After the reconstruction,the WWTP operates well,and the effluent quality meets the first level criteria.
