| Abstract: | The paper analyzes the influence of lead toxicity by anaerobic granule sludge inhibition and recovering experiments.The result shows that there are different inhibition types at differ ent lead contents.Higher lead content leads to more inhibition granular sludge,and at the same time,the time of gas recovery is different.Lower lead content per microorganism results in sooner sludge recovery.Microorganisms have a good ability to resist lead toxicity. |
| Keywords: | lead granular sludge toxicity inhibition |
