| 中文摘要 |
| 用厌氧-缺氧-好氧中试反应器系统对城市废水进行处理.结果表明,此系统可去除90%总COD、89%TSS、93%VSS,氮和磷的去除率分别为80%和40%.在此系统的缺氧相污泥中,脱氮硫杆菌的最高含量(MPN)、最高脱氮作用率、氧化Na2S的最高浓度、S2-的最高污泥负荷率分别为1.1×108/g VSS、3.6mg NO3-/g VSS·h、1750mg/L和25mg S2-/g VSS·d. |
| 英文摘要 |
| A pilot reactor of anaerobic-anoxic-aerobic process was operated to treat municipal wastewater.The results indicated that the process was able to remove 90% total COD, 89% TSS, 93% VSS, and the removal rates of nitrogen and phosphorus were 80% and 40%, respectively.In anoxic phase, the maximum number ( MPN ) of Thiobacillus denitrificans, the maximum denitrification rate, the maximum concentration of oxidizing Na2S, and sludge loading rate of S2- were 1.1×108/g VSS, 3.6mg NO3-/g VSS·h, 1750mg/L and 25mg S2-/ gVSS·d,respectively. |
