摘要：A treatment system combining the coal-based carbon membrane with electrochemical oxidation process was designed for the enhanced disinfection performance. The effects of various parameters including electric voltage, Vibrio cholerae density, rotate speed, electrical conductivity, and electrode distance on the disinfection performance were carried out. The results showed the disinfection performance of the carbon membrane was significantly improved by coupling with electrochemical oxidation process and 2.0 V electric voltage was recommended. High Vibrio cholerae density usually increased the load of the treatment system, resulting in low permeate flux and disinfection efficiency. High rotate speed prompted the permeation of Vibrio cholerae cells, which inevitably made some of Vibrio cholerae cells penetrate though the carbon membrane quickly without being treated. High conductivity favored the electrochemical disinfection due to the generation of more total residual chlorine (TRC). Reducing electrode distance intensified electrochemical reactions and produced a large amount of gas bubbles, hindering water permeate.
