摘要:
改良A2O工艺运行过程中，生物池污泥膨胀及其引起的泡沫一直是该工艺的控制难点。郑州市某污水处理厂二期工程于2019年八九月份出现丝状菌增多、池面泡沫大量聚集等情况。该污水处理厂采用投加复合药剂快速消除泡沫、生物池污泥快速置换、投加次氯酸钠杀灭丝状菌等3种措施轮流进行控制。至11月上旬,生物池污泥指数开始下降并稳定在115 mL/g左右，达到了有效控制污泥膨胀及其伴随泡沫的目的。
Abstract:
The sludge bulking and its foam problem in the biological tank have always been the control difficulties of improved A2O process. In the second phase of a wastewater treatment plant (WWTP) in Zhengzhou, filamentous bacteria increased and a large number of foam appeared and gathered on the surface of the tank in August and September 2019. The WWTP was controlled in turn by adding composite chemicals to rapidly eliminate the foam, rapidly replacing the sludge in the biological tank, and adding sodium hypochlorite to kill filamentous bacteria. The sludge index of the bioreactor began to decrease and stabilized at about 115 mL/g by early November, which effectively achieves the purpose of controlling sludge bulking and its foam.
