Conditioning of sewage sludge by Fenton's reagent combined with skeleton builders.

摘要: Abstract Physical conditioners, often known as skeleton builders, are commonly used to improve the dewaterability of sewage sludge. This study evaluated a novel joint usage Fenton’s reagent and referred F–S inorganic composite conditioner, focusing on their efficacies optimization major operational parameters. The results demonstrate that conditioner for conditioning sludge is viable alternative conventional organic polymers, especially when ordinary Portland cement (OPC) lime builders. Experimental investigations confirmed Fenton reaction required sufficient time (80 min in this study) degrade organics optimal condition process was at pH = 5, Fe2+ = 40 mg g−1 (dry solids), H2O2 = 32 mg g−1, OPC = 300 mg g−1 lime = 400 mg g−1, which specific resistance filtration reduction efficiency 95% achieved.
