摘要
Abstract
Sludge pyrolysis residue,a byproduct of sludge treatment,possesses significant potential as a recyclable resource owing to its abundant silicon,aluminum,iron and other compounds.Porous zeolite and polyaluminum ferric chloride(PAFC)were prepared from sludge pyrolysis residue by the combination of physical and chemical methods,and their treatment properties were investigated.The results showed that the zeolite synthesized by hydrothermal method showed a typical porous structure,and the maximum adsorption of methylene blue could reach 31 mg/g at room temperature.Meanwhile,the PAFC was synthesized via acid leaching and polymerization techniques.As expected,the prepared PAFC showed an excellent removal effect for phosphorus from wastewater treatment plant.Furthermore,the total phosphorus of the effluent could well meet the standards of Integrated Wastewater Discharge Standard of Yellow River Basin in Shaanxi Province.It is expected that the strategy can provide a sustainable path for the resource utilization of sludge residue.关键词
