Abstract
Advanced adsorbents for selective removal of excessive phosphorus in actual surface water bodies and safe disposal of waterworks sludge are essential due to environmental risks and resource wastes. Herein, a strategy of killing two birds with one stone was proposed to design a La(OH)3/iron-based waterworks sludge/polyacrylonitrile (La(OH)3/IS/PAN) membrane for selective removal of phosphate. In this strategy, nano-La(OH)3 was well-dispersed on IS surface to realize functionalization of IS, and PAN electrospun nanofibers prevented powdered La(OH)3/IS from loss. The membrane showed a maximum adsorption capacity of 19.89 mg/L at 25 °C and remained relatively stable phosphate adsorption capacity under various anions interference. More importantly, after adsorption, the total phosphorus (TP) of the actual surface water from Yudai river was reduced to meet the requirement of the surface water standard of China, Ⅱ (GB 3838–2002). The work provides a novel way to overcome the challenges posed by eutrophication and sludge problems for industrial applications.
