| 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，最高脱氮作用率，氧化Ｎａ２Ｓ的最高浓度，Ｓ＾２－的最高污泥负荷率分别为１．１×１０＾８／ｇＶＳＳ，３．６ｍｇＮＯ３＾－／ｇＶＳＳ·ｈ，１７５０ｍｇ／Ｌ和２５ｍｇＳ＾２／ｇＶＳＳ·ｄ。

| Abstract: | 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. |
