摘　　要：用甲烷气体的产气速率来衡量厌氧颗粒污泥的产甲烷活性 ,以厌氧颗粒污泥处理含不同浓度氯化钠和铬鞣剂的废水 ,研究氯化钠和铬鞣剂对厌氧颗粒污泥的毒性。研究结果可为制革废水的厌氧处理提供参考依据。Using the rate of methane yield as an activity standard of anaerobic granular sludge, the effects of some toxicants on anaerobic reaction of granular sludge were studied by experiments that wastewater was treated at different concentrations of sodium chloride and chrome tanning agent individually. The conclusions drew according to experiments may be important reference to tannery wastewater treatment.
