摘　　要：针对为地沟油等废弃油脂研发而成的新型高效浮选药剂BFA（bioflotation agent），进行了实验室和工业现场浮选试验，通过调控药剂配方和药剂用量，确定实验室浮选效果和工业现场效果，分析对比后确定了最佳浮选药剂及用量。浮选试验结果表明，使用BFA浮选药剂精煤灰分范围分布在4．74％～8．62％，浮选完善指标最高达64．00％，可燃体回收率高达92．08％。工业现场试验结果显示，BFA药剂浮选效果优于传统浮选药剂，药剂耗量减少24％，精煤灰分保持在11级，尾矿灰分提高了9．32%。To solve the problems of food safety caused by waste cooking oils and fats （WCOF）, WCOF-to-BFA （bio-flotation agent） application as an innovative process for WCOF is proposed to alleviate energy shortage. BFA was carried out in the scene of the laboratory and industrial flotation experiment. The flotation effect of BFA in the laboratory and industrial process were investigated by regulating formulation and dosage of the series BFAs. The optimal reagent and dosage of BFAs were ascertained. Results indicate that the ash content of concentrate is 4.74% to 8.62%, the optimal ash content of concentrate, combustible material recovery and flotation perfect index are 7. 78%, 64.00% and 92. 08%, respectively. Besides, the BFA dosage is 24% less than the regular diesel and octanol dosage in industrial scale test. The ash content of concentrate keeps up the 11th level, and the tailing ash content is higher by 9.32% than those obtained with the regular flotation agent.
