Aerobic biological treatment of landfill leachate
There is an ongoing need to treat leachates from landfills using approaches that avoid expensive installation and operating costs. Faced with such a problem, Powys County Council (Wales, UK) developed a treatment system based on practical experience. Leachate was re-circulated through aeration towers containing a biofilm supported on plastic media before being polished in reed/filter beds. Inve...
متن کاملTreatment of mature landfill leachate by chemical precipitation and Fenton advanced oxidation process
Background: Mature landfill leachate is a complicated mixture which is resistant to biological treatment processes. The treatment of mature landfill leachate by struvite precipitation and Fenton oxidation was the main objective of the current research. Methods: Struvite with the phosphate/ammonia/magnesium molar ratio of 1/1/1.05 was considered during all experiments. Five initial pHs of 3, 4,...
متن کاملAdvanced landfill leachate treatment using a two-stage UASB-SBR system at low temperature.
A two-stage upflow anaerobic sludge blanket (UASB) and sequencing batch reactor (SBR) system was introduced to treat landfill leachate for advanced removal of COD and nitrogen at low temperature. In order to improve the total nitrogen (TN) removal efficiency and to reduce the COD requirement for denitrification, the raw leachate with recycled SBR nitrification supernatant was pumped into the fi...
متن کاملTreatment of old landfill leachate with high ammonium content using aerobic granular sludge
Background Aerobic granular sludge has become an attractive alternative to the conventional activated sludge due to its high settling velocity, compact structure, and higher tolerance to toxic substances and adverse conditions. Aerobic granular sludge process has been studied intensively in the treatment of municipal and industrial wastewater. However, information on leachate treatment using ae...
متن کاملStudy on Sludge Start-up of SH-A Process for Mature Landfill Leachate Treatment
The research was on the sludge start-up of SH-A process for mature landfill leachate treatment, SH-A is the combined SHARON (Single Reactor High Activity Ammonia Removal Over Nitrite) ANAMMOX(Anaerobic Ammonium Oxidation). The seed sludge was from Yangeryu Landfill of Anshan, Liaoning province of China. The landfill leachate was used to cultivate the sludge. The results showed that the start-up...
