为了解决兰炭废水生化处理效果不理想的难题,借鉴医药废水生化处理工艺,从医药废水生化处理系统的污泥中筛选了对多酚类具有抗性的特效菌群.将驯化后的特效菌群用于处理兰炭废水,通过静态试验验证了特效菌群对兰炭废水具有较好的解毒效果,并通过动态试验模拟兰炭废水生化处理工况.静态和动态试验研究了特效菌群对降低兰炭废水毒性、COD、有机氮和总氮的效果,结果表明,特效菌群能够有效降低兰炭废水的毒性,最小抑菌浓度从 3%提升至30%以上,生物毒性下降10 倍,COD去除率达到 62.19%,有机氮去除率达到 56.9%,废水的B/C值从 0.12 提升至 0.43,处理出水的可生化性显著提升.该特效菌群可以用于兰炭废水的解毒预处理,通过解毒预处理能够提升兰炭废水的生化处理效果.
Experimental study on specific bacterial community construction and its effect on semi-coke wastewater treatment
As semi-coke wastewater is difficult to be biodegraded,pharmaceutical wastewater biochemical treatment process was adopted,specific bacterial community which is resistant to polyphenols was screened from sludge in pharmaceutical wastewater biochemical treatment system.The acclimated specific bacterial community was used to treat semi-coke wastewater,and its good detoxification performance was verified through static test,besides,the biochemical treatment situation of semi-coke wastewater was simulated using dynamic test.The ef-fect of the specific bacterial community on toxicity decrease and removal of COD,organic nitrogen and total ni-trogen in semi-coke wastewater,were studied through static test and dynamic test.The results showed that,spe-cific bacteria community could effectively reduce the toxicity of the semi-coke wastewater,the minimum inhibito-ry concentration(MIC)increased from 3%to above 30%,the biological toxicity decreased by 10 times,the re-moval rates of COD and organic nitrogen reached 62.19%and 56.9%respectively,the B/C value of the wastewa-ter was increased from 0.12 to 0.43,the biodegradability of the effluent water was significantly promoted,The said specific bacterial community can be used for detoxification pretreatment of semi-coke wastewater,and the biochemical treatment effect of semi-coke wastewater can be improved by detoxification pretreatment.
