The invention belongs to the field of solid waste recycling, and particularly relates to a magnetic reinforced fly ash imprinted photocatalyst for degrading phenol-containing wastewater, which solves the problems of poor selectivity and difficult separation and recovery of common photocatalysts, and mainly comprises the following components: firstly, pretreating and activating the fly ash, then magnetizing the activated fly ash, then loading titanium dioxide on the magnetic fly ash, and finally preparing the molecularly imprinted titanium dioxide/fly ash phenol catalyst by a molecular imprinting technology. The invention utilizes the excellent adsorbability and stable chemical property of the cheap fly ash to prepare the photocatalytic material with good photodegradability, easy recovery and excellent selectivity, and can quickly treat the phenolic wastewater, thereby realizing the purpose of treating wastes by wastes. |
