Two types of reagent were selected, one was inhibitor, and the other was uncoupler. Inhibitor Cu/Zn- and uncoupler 2, 4-dinitrophenol (dNP) -containing short-term batch experiments showed that they both can reduce the sludge yield effectively.

• 间歇性试验结果表明,在适当的投加量下,抑制剂Cu、Zn和解偶联剂dNP(2,4-二硝基酚)都能够有效地降低污泥的产率,但抑制剂对污水处理效果的影响要远远大于解偶联剂。
