| 摘 要： | 采用3,3′,4′,5四氯水杨酰苯胺(TCS)作为代谢解偶联剂添加到活性污泥工艺中,连续曝气分批培养实验结果表明,TCS以固体方式投加的效果好于液态投加,每天投加12mg,相当于液态浓度1mg/L,可使污泥产量49%。在30d的运行期间,每天分别在4个反应器中添加TCS5.0、8、10和12mg,出水氨氮及总氮浓度均未受影响,但污泥的COD去除能力有所下降,当投加12mg时,COD去除率比对照下降了8.9%。污泥的SVI值有所上升,但沉降性能未见有明显影响。污泥微生物的种群结构发生了改变。

| Abstract: | Uncoupled metabolism refers to the use of 3. 3' , 4'. 5-tetrrachlorosalicylanilide (TCS) as a metabolic uncoupler added to activated sludge to reduce residual sludge yield. The experimental result indicates that when TCS dosing reaches 12 mg/L. it is possible to reduce sludge by 20%. Meanwhile, there is no evidence of removals of NH3 - N and TN; however COD removal decreases a little with increase of SVI. |
