采用树脂吸附与生物强化技术相结合的方法,对高盐废硝基苯废水进行降解处理。试验确定的最佳工艺条件:(1)通过树脂的选择性吸附去除废水中的硝基苯,流速在10BV/h,处理水量320BV;(2)采用生物强化的方法对树脂所吸附的硝基苯进行生物降解,经过160h专效菌种的降解,树脂所吸附的硝基苯被彻底降解,同时树脂的吸附能力得到恢复;(3)经过两个月的连续试验,发现树脂的吸附能力在起始阶段有所下降,随后保持稳定。
Through combining the merits of resin adsorption and bio-intensifying processes,the nitrobenzene wastewater containing high salinity has been treated. The optimum situations are: (1)removing nitrobenzene from wastewater by the selective adsorption of resin at the flux density of 10 BV/h, the treated volume is 320 BV; (2)the adsorbed nitrobenzene is biodegraded by bio-intensifying. After 160 h degradation of specific fungus,the nitrobenzene adsorbed in resin is thoroughly metabolized and the adsorption capacity of resin is recovered; (3) after a two-month continual experiment, the result shows that the adsoption capcity of resin decreases firstly and then remains stable.
