摘　　要：结合污染源的火甩直和污染源的毒理作用，对普通过磷酸钙生产系统中的氟化物进行了Yong态学研究，计算了各种氟化物的潜在危害系数，得出了环境负效应ENE。结果表明：各种工艺水平下总氟化物的ENE几乎是一样的，且产品熟化过程中逸散氟的ENE占到系统排放氟化物的ENE的83％～92％。Exergoecologic evaluation of fluoride in calcium superphosphate process system was studied by the combination of exergy and poisonous effect of fluoride. Potential harm coefficients of fluoride and environmental negative effect (ENE) were calculated. Results showed that total ENE of fluoride was almost the same value at various process level, and the ENE of fluoride dissipated into the atmospheric environment in the mature process was 92%～ 96% of the ENE of fluoride emission in environment.
