硫酸钠和硫化钠对厌氧反应微生物的毒性研究

Study on the toxicity of sodium sulfate and sodium sulfide on anaerobic microorganism

以厌氧活性污泥处理含不同浓度的硫酸钠和硫化钠的废水,研究了Na2SO4和Na2S对厌氧污泥的毒性。以甲烷气体的体积产量来衡量活性污泥中产甲烷菌的活性,为制革废水的厌氧处理提供依据。

The effects of some toxicants on anaerobic reaction were studied by experiments that wastewater was treated at dif-ferent concentrations of sodium sulfate and sodium sulfide individually. The conclusions drew according to experiments may be important reference to tannery wastewater treatment.
