首次采用一种新型吸附材料———活性炭纤维作为吸附剂,以制药厂氯霉素车间排放的硝基废水为对象,系统研究了活性炭纤维对硝基废水的表观平衡吸附量、动态穿透特性、吸附影响因素以及吸附剂的再生性能。研究表明活性炭纤维处理硝基废水吸附容量大,吸附速度快,具有优异的再生性能,可以替代传统的颗粒状活性炭。

A new absorbent, activated carbon fiber, has been used to treat nitro-g roup wastewater discharged f rom the chloramphenicol production in the pharmaceutical facto ry for the first time.The parameters of equilibrium adsorption quanti ty, dy namic breakthrough characterist ics, adso rptio n effect factors and the regeneration character in the process of the t reatment are systematically described.The results indicates that the adsorption capacity is large, the adsorption rate is fast, and the regeneration character is excellent.It is seen that the activated carbon fiber could take the place of granular activated carbon.
