摘要： The present invention belongs to the technical field of environmental engineering and provides a method for constructing a multistage food chain biofilm system enhanced by electrochemistry and an application in pharmaceutical wastewater. A flow-through electrochemical degradation module is constructed based on P/F—TiO2-n porous membrane electrodes, and a multistage flow-through composite electrochemical-biological submerged fixed film reactor is constructed jointly with the PA-N-rGO fixed fiber carrier and applied to deep purification of high-risk substances in pharmaceutical wastewater. The flow-through electrochemical degradation module can also effectively degrade antibiotics resistance genes and refractory organics in the water, improve the biodegradability of the wastewater and improve the degradation performance and load of shock resistance of the system, so the multistage flow-through composite electrochemical-biological submerged fixed film reactor can realize the high-efficiency low-consumption treatment of pharmaceutical wastewater and effectively reduce the yield of excess activated sludge.
