Activated sludge process is in common use for the treatment of wastewater;which also generates a large quantity of excess sludge daily as a byproduct that requires additional treatment and disposal.Adding metabolic uncouplers is an effective method to reduce sludge production.Five metabolic uncouplers,2-aminophenol(AP),2,4-dinitrophenol(DNP),2,4,6-trichlorophenol(TCP),3,3',4,5-tetrachlorosalicylanilide(TCS),malonic acid were invested and found that AP of 20 mg/L,DNP of 15 mg/L,TCP of 8 mg/L,TCS of 1.2 mg/L and...

Activated sludge process is in common use for the treatment of wastewater;which also generates a large quantity of excess sludge daily as a byproduct that requires additional treatment and disposal.Adding metabolic uncouplers is an effective method to reduce sludge production.Five metabolic uncouplers,2-aminophenol(AP),2,4-dinitrophenol(DNP),2,4,6-trichlorophenol(TCP),3,3',4,5-tetrachlorosalicylanilide(TCS),malonic acid were invested and found that AP of 20 mg/L,DNP of 15 mg/L,TCP of 8 mg/L,TCS of 1.2 mg/L and malonic acid of 15 mg/L could reduce observed growth yield(Yobs) of the sludge by 62.39%,63.75%,59.40%,34.58% and 53.75% simultaneously with lower reduction of COD removal efficiency,respectively.The effects of malonic acid and TCP on sludge characteristics in SBR were studied in detail and found that both of TCP and malonic acid could reduce the production of sludge obviously without affecting COD removal efficiency generally.However,SVI values of sludge with malonic acid increased greatly after 6 days of adding malonic acid,but the values with TCP were increased slightly and the settlability of sludge was not affected.

活性污泥法是最常用的污水处理技术,但它同时会产生大量的剩余污泥,需要进行额外的处理和处置。活性污泥的解偶联代谢能有效地减少剩余污泥的产量。比较了5种代谢解偶联剂,即2,4-二硝基苯酚(DNP)、邻氨基苯酚(AP)、2,4,6-三氯苯酚(TCP)、3,3’,4,5-四氯水杨酰苯胺(TCS)、丙二酸的污泥减量效果和对COD去除能力的影响。结果表明,当它们在各自的最佳质量浓度20、15、4、1.2、15 mg/L时,污泥的表观增长系数分别降低了62.39%、63.75%、59.40%、34.58%和53.75%,而COD去除率仅有轻微下降。重点研究了15 mg/L的丙二酸和4 mg/L的TCP对SBR系统运行效能和污泥沉降性能的影响。发现在长期运行过程中,两者都能有效降低系统的污泥产量,而对COD去除率的影响较低,但使用丙二酸6 d后极大地影响了污泥的沉降性能,而TCP对污泥的沉降性能影响很小。
