Study on pretreatment of landfill leachate by magnetic flocculation
|
Abstract:
Landfill leachate is a kind of high concentration organic wastewater.In this study,the technology of magnetic flocculation was used to pretreat the landfill leachate,the testing factors included optimum dosage of magnetic carriers,agglomerants and flocculants,the influence of pH and dosing sequence.And the results were compared with chemical flocculation and magnetic flocculation.The results reveals that 42% of COD removal efficiency,92% of turbidity reduction,88% of chroma removal,79% of ammonia nitrogen r...
