摘　　要：应用连续流搅拌槽式反应器（CSTR）对安普霉素废水进行产酸发酵和去毒处理，在进水COD质量浓度为5000-8000mg／L，HRT为8h的条件下，对安普霉素生产废水的COD去除率平均为21．53％，而HRT为12h时平均为17．62％．HRT为8h和12h对悬浮物（SS）的平均去除率分别为56．78％和53．05％；对氩氮的平均去除率分别为11．05％和6．39％．经产酸发酵处理过的安普霉亲生产废水，其毒性被去除，BOD5／COD（B／C）从处理前的0．35：分别提高到0．42以上，去除单位重量COD的甲烷产量达到164mL／g以上，可采用产甲烷相进行更进一步的有效处理．A continuous stirred-tank reactor （CSTR） was used to pretreat apramycin process wastewater by acidogenic fermentation. At hydraulic retention time （HRT） of 8 h, with a influent concentration of 5 000-8 000mg/L, the average removal rates of COD, suspended solid （SS） and ammoniacal nitrogen were 21.53%, 56. 78% and ll. 05%, respectively. When the HRT increased to 12 h, the average removal rates of COD, SS and ammoniacal nitrogen decreased to 17. 62%, 53.05% and 6. 39%, respectively. The ratio of BOD5/COD for the treated wastewater increased from the original 0. 35 to above 0. 42, while the specific formation rate of methane by COD removal reached 164 mL/g, indicating that the biodegradability of the wastewater had been enhanced observably and the toxicity to the anaerobic microorganism had been eliminated successfully.
