摘　　要：以某酒精厂的酒精废水处理工程为对象,分析导致UBF反应器酸化的原因,探讨UBF反应器酸化后的恢复措施。工程运行表明,反应器内酸化后表现为pH值下降、COD去除率降低、VFA值升高、产气率减少并有大量污泥上浮,采用好氧出水回流洗出反应器内大量的挥发酸,可使酸化后的UBF反应器较快恢复正常运行。Taking alcohol wastewater treatment project as research object, the reasons leading to the acidification of UBF reactor are analyzed, and the remedy methods are discussed. The project operation indicates that after the acidification of UBF reactor happens, pH is dropped, COD removal rate is reduced, VFA is increased, gas production rate is reduced, and a lot of sludge is floated. Displacing the acidified fermenting liquor with aerobic effluent recycle can solve the acidification problem effectively.
