摘要
Abstract
Coal chemical industry wastewater is a kind of refractory industry wastewater with high salt content. In order to improve biodegradation efficiency of coal chemical industry wastewater,a halotolerant bacteria CCZU-R6 was isolated from the sewage of a coal chemical enterprise. It was identified asBacillus sp. by its morphological properties and 16S rDNA sequence analysis. Using the method of single factor experiment,the effects of degradation conditions were studied. The optimum treatment conditions for simulated saline wastewater were pH 7.0,temperature 35℃,inoculum concentration 500mg/L,and the maximum salinity tolerance was about 11%. Substrate spectral analysis showed that CCZU-R6 could degrade phenol,benzyl alcohol,and methanol. The COD removal rate was up to 93% when the coal chemical industry saline wastewater was treated by CCZU-R6 for 24 hours under the optimal conditions. The results showed that CCZU-R6 could effectively degrade saline wastewater in coal chemical industry,with good commercial application potential.关键词
