Abstract
The simulant wastewater containing high concentration ammonia-nitrogen was treated by electro-chemical oxidation process in intermittent experiment. The influences of different factors including plate distance,current density, chloride ion concentration and initial pH on ammonia-nitrogen and total nitrogen removal were studied.According to the results of the test, the optimal reaction condition was determined as follows: plate distance was 40mm，current density was 90mA/cm²，chloride ion concentration was 8000mg/L, initial pH was 10。Under the above condition,the total nitrogen concentration reduced from 2000 mg/Lto 280mg/L when the reaction time was 8h, and the removal rate reached 86%. As we can see, the effect of the treatment is quite positive.
