摘　　要：某制药厂排放废水中的有机物以难降解大分子有机物为主,可生化性差,并且氨氮和总氮浓度较高,针对此,设计了3种组合工艺对其进行中试研究。结果表明,以多级耦合生物处理系统为核心,辅以两级臭氧氧化/生物炭吸附的组合工艺对该类废水具有较好的处理效果,出水水质可稳定达到国家一级A排放标准;臭氧后置投加能有效发挥其氧化作用,臭氧利用率高;采用两级臭氧氧化/生物炭吸附组合工艺,能有效提高臭氧利用率,延长生物炭的使用寿命。The effluent from cule organics with low biodegradab a pharmaceutical plant is mainly composed of persistent macromole- ility, high ammonia and total nitrogen concentration. Therefore, the study on the effect of three combined processes was conducted at pilot scale. The results showed that the combined process, which contained the multi-level biological treatment system as a core and the two-stage ozone/biological activated carbon adsorption as a secondary, had better treatment efficiency, and the ef- fluent quality could reach the level A criteria of the national discharge standards. Post-dosing of ozone could pre-oxidize effectively and achieve a high utilization rate. The two-stage ozone/biological activated carbon adsorption process made a contribution to ozone utilization and activated carbon life cycle.
