| Abstract: | In this study,stripping technology is used to pretreat the semi-coke wastewater for reducing its ammonia and COD content,so as to achieve the conditions of subsequent biological treatment.The results show that：when the temperature is controlled at 50 ℃,the pH value of semi-coke wastewater isadjusted to 9.6,the reaction time is 1.5 hours,and the ammonia nitrogen and COD removal rates reach 75% and 26%,which meet the requirements of subsequent biological treatment. |
