A bacterial strain LM1 which can aerobically degrade sorghum liquor wastewater was isolated from the sewage water sample of a sorghum liquor manufacturer with dilution plate method.This strain was identified as Rhodococcus sp.based on its morphological observation and 16S rDNA sequence analysis.The characteristic of its liquor wastewater degradation was studied.The optimal conditions for degrading sorghum liquor wastewater were pH 7.0,temperature 30 ℃ with 5% inoculation amount.Under these conditions,(81.0 ± 2.4)% reduction in chemical oxygen demand (COD),(81.2 ± 4.1)% reduction in total organic carbon (TOC) and (66.6±0.1)% reduction in total nitrogen (TN),and (72.7±0.2)% reduction in total phosphorus (TP) of the spent wash could be achieved within 72 h by Rhodococcus sp.LM1.The value of COD and TN in effluent was (475.3±60.0) mg/L and (16.6±0.1) mg/L,which were under the highest concentration of the second discharge standard(COD≤400 mg/L) and the first discharge standard (TN≤25 mg/L) of water pollutants for fermentation alcohol and distilled spirits industry (GB 27631-2011),respectively.The effluent was further treated by Fenton oxidation as the advanced treatment,and the concentrations of COD,TOC,TN,TP and de-colorization ratio were (120.0±7.0) mg/L,(36.0±3.5) mg/L,0.1 mg/L,(13.3±0.5) mg/L and 99.8%,respectively,fitting with the standard of discharging wastewater.
