| Abstract: | The effects of 3 external carbon resources,such as glucose,starch and sodium acetate,on the biodegradation of flotation reagents in simulated ore milling wastewater by SBR process were studied.The experimental results show that: When the residence time is 2 h,the initial concentrations of aniline aerofloat(dianilino dithiophosphoric acid),xanthate(sodium n-butyl-xanthate),diethyldithiocarbamate(Sodium diethyldithiocarbamate trihydrate) are 120,6,3 mg/L respectively,and starch is used as the external carbon ... |
