| 摘 要： | 对某浮选厂浮选废水进行混凝沉淀+活性碳吸附预处理,然后进入生化系统,厌氧池、好氧池停留时间为10h.结果证明:进水COD为400～700mg/L,出水74～145 mg/L,去除率达75.8%以上,首次成功地将生物法应用到铅锌选矿废水的处理,若对该工艺进行适当调整,完全可以使出水达到排放或回用标准.

| Abstract: | Flotation wastewater was treated by the combined processes of physicochemical pretreatment-hydrolysis acidification-biological contact oxidation.The HRT of Anaerobic reactor and Aerobic reactor was 10 hours.The results demonstrated that the concentration of COD decreased from 400～700 mg/L to 74～145 mg/L through the combined processes,the average removal rate was 75.8%.The biological method first successfully apply to the lead-zinc flotation wastewater,if the appropriate adjustment was made for the processes,their effluent could meet the discharge or reuse standard. |
