摘　　要：以生物炭为载体负载壳聚糖、磁性纳米Fe_(3)O_(4)制备了一种生物炭负载纳米Fe_(3)O_(4)新型吸附剂,考察了其吸附性能及可再生性能。结果表明,在pH为7、温度为30℃、吸附剂投加质量为0.4 g时反应120 min,COD、油、浊度的去除率分别为83.34%、92.21%和97.82%,达到回注水标准。吸附剂经过5次再生后对废水仍有较好的去除效率。新型生物炭复合吸附剂对含油废水有很好的吸附效果,且其优越的再生性可以有效地节约成本。Biochar-loaded nano-Fe_(3)O_(4)adsorbent,a novel composite adsorbent,is prepared by using biochar as the carrier to load chitosan and magnetic nano-Fe_(3)O_(4),and its adsorption performance and regenerative performance are evaluated.Test results show that the removal rates of COD,oil and turbidity reach 83.34%,92.21%and 97.82%,respectively when pH=7,the temperature remains at 30℃,adsorbent dosage is 0.4 g and the reaction lasts for 120 min.The water after treatment reaches the standard for re-injection water.After five times of regeneration test,the adsorbent still exhibits high and good removal efficiency for wastewater.This novel biochar composite adsorbent presents good adsorption effect on the oil-containing wastewater,and its superior regeneration performance effectively saves the economic cost.
