This work deals with the natural degradation of leachate from an old reclaimed landfill by means of a biological pond. Hamra is a municipal waste landfill with a limited formation of leachate, which has already been reclaimed. Leachate in this location is disposed of using natural biogeochemical method, and it is subsequently discharged into a surface stream. The main issue dealt with here is t...

Landfill leachate has the characteristics of high ammonia nitrogen content, concentration organic matter and low carbon ratio. Traditional biological treatment technology is difficult to meet increasingly stringent emission standards. Ammonia main pollutant in landfill leachate. The ammonia-nitrogen-rich not only poses a threat surrounding environment, but also adverse effects on subsequent Ana...

aims: municipal landfill leachate contains high concentrations of heavy metals, organics, ammonia . t he efficeincy of electrochemically removal of heavy metals from landfill leachate was studied. materials & methods: the leachate was obtained from kahrizak landfill in south of tehran. the experiments were carried out by batch process. the 2liter batch reactor was made of glass. there were eigh...

Advanced oxidation processes like Fenton and photo-Fenton have been effectively applied to oxidize the persistent organic compounds in solid waste leachate and convert them to unharmful materials and products. However, there are limited data about application of Fenton-like process in leachate treatment. Therefore, this study was designed with the objective of treating municipal landfill leacha...

Landfill leachate, especially when produced in old municipal solid waste landfills, is a challenging type of wastewater which contains variety toxic substances. The existence pollutants the landfill leachate primarily due to inadequate separation at source. Pretreatment on site must for be safely released into environment. One-step treatment insufficient since has complex composition that spati...
