硫酸盐还原菌活性污泥对磺胺甲噁唑的吸附和降解初步研究

Sulfamethoxazole is a typical pharmaceuticals and personal care products, it along with human metabolic activity into the environment, it has threatened the aqueous environment system due to their high solubility and degradability. This study evaluated degradability of Sulfamethoxazole by sulfate-reducing bacteria activated sludge and revealed its degradation mechanism using batch experiments. The results showed that sulfate-reducing bacteria sludge achieved the removal of Sulfamethoxazole by adsorption and biodegradation, and adsorption removal was low, only about 7 percent, biodegradation is the main degradation mechanism. For certain concentration Sulfamethoxazole, Sulfamethoxazole can be removed by sulfate-reducing bacteria activated sludge within a certain time.
