| 摘要: |
| 为探讨腐殖活性污泥的生物化学特征及其作用机理,对腐殖生物填料进行扫描电镜和能谱(SEM-EDAX)测定,表明填料中主要组成元素为C、O、Si,同时含有少量Al、S、Fe. 腐殖活性污泥与普通活性污泥中若干特征菌群的对比分析表明,腐殖活性污泥中的一般细菌总量、硝酸菌、亚硝酸菌、脱氮菌及放线菌含量明显高于普通活性污泥;腐殖活性污泥中有机质的质量分数比普通活性污泥低,但腐殖酸及富里酸和胡敏酸质量分数明显高于普通活性污泥;腐殖活性污泥法运行的SBR反应器对CODCr、TP和TN的去除效果优于普通SBR反应器,分别高出4％、14％和10％． |

| Abstract: |
| To thoroughly investigate biochemical characteristics of the humic activated sludge and action mechanism, the humic biological pellets were tested by means of SEM-EDAX. The results show that the main composition elements in humic biological pellets are C, O, Si, and there are small amounts of Al, S, Fe. Compared to conventional activated sludge, the number of typical bacteria, nitrifying bacteria, nitrosobacteria, denitrifier and actinomycetes in humic activated sludge were significantly higher. Organic matter content in humic activated sludge is less than that in conventional activated sludge, but the humic acids content is higher. The humification degree of humic activated sludge is considerably higher than that of conventional activated sludge. The SBR reactor operated under humic activated sludge process performed excellent pollutant removal efficiency than conventional SBR reactor, the removal efficiency of CODCr, TN and TP is 4％, 10％ and 14％ higher respectively. |
