Abstract: This research is mainly about the electrochemical oxidation technology for the treatment of waste water from biochemical pool of the acrlic fiber company, using the national standard test method for COD, NH3-N, chroma and chlorion as four indicators for analysis. The results show that chroma, ammonia nitrogen and COD can be effectively removed in the process of electrolysis. Among them, ammonia nitrogen removal rate is up to 100%, while the chroma removal rate is up to 99%,and COD removal rate is up to 89%. After the completion of the reaction, chlorion content also can be reduced to a national level of discharging standard, which indicates that electrochemical catalytic oxidation technology has a rather good application prospect. Through the analysis, we can make a conclusion that chroma and ammonia nitrogen can be completely removed within 10 min and 30 min respectively. The ammonia nitrogen removal rate is a function of electrolytic voltage, and chlorion has response characteristics of the first order reaction, COD removal rate constant and chlorions removal rate constant has a good correlation. This will be instructive for the design of electrochemical oxidation reactor and industrial operation.
