The process of Nitrogen Stripping-Coagulation Air Floatation-UASB-Contact Oxidation has been designed and is used to treat Landfill Leachate somewhere in Nanjing, and all the effluent can fully meet the National Integral Discharge Standard after steady operation of half a year. After introducing the process of wastewater treatment system,a technical summary is given to the debugging and operating process of the system. The technics is a very efficient method of treating Landfill Leachate which is filled with high ammonia nitrogen and high turbidity.
