处理高浓度DDNP废水的白腐真菌培养基的优化研究

Study on optimization of wastewater with DDNP of high concentration by medium of white rot fungus

优化研究了有效处理高浓度DDNP(二硝基重氮酚)废水的白腐真菌培养基。采用正交设计法对白腐真菌的培养基进行优化。实验表明,白腐真菌的物化条件为:T=37℃,pH=4.5,摇床转速130r/min;白腐真菌的最佳培养基为:葡萄糖10g/L,酒石酸铵0.7g/L,KH2PO41g/L,NaHPO40.2g/L,MgSO40.4g/L,VB1 0.005g/L,FeSO40.1g/L,ZnSO40.03g/L,MnSO40.005g/L。

In order to research the optimization of effective treatment on wastewater with DDNP of high concentration by medium of white rot fungus.Orthogonal design is used to optimize the medium of white rot fungus.Experiments show that physical and chemical conditions of white-rot fungus are：T=37 ℃,pH=4.5,stirring speed=130r/min.The best medium of whiterot fungus：glucose 10g/L,ammonium tartrate 0.7g/L,potassium dihydrogen phosphate 1g/L,sodium hydrogen phosphate 0.2g/L,magnesium sulfate 0.4g/L,VB10.005g/L,ferrous sulfate 0.1g/L,zinc sulfate 0.03g/L,manganese sulfate 0.005g/L.
