摘 要：
采用三维电化学法预处理富马酸废水,重点考察废水的NH_4~+-N去除率。基于BBD响应曲面法,探究了电压、反应时间和初始pH的单独及相互作用,并建立氨氮去除率的数学模型。结果表明,影响因子显著性顺序为电压>反应时间>初始pH,三者之间有一定的交互作用,但并不显著;数学模型回归性较好,预测氨氮最大去除率为88.7%,最佳运行条件组合为电压28.41 V、反应时间87.27 min、pH 4.55,验证试验结果为87.6%,与预测值的偏差仅为1.2%。

摘 要：
The three-dimensional electrochemical method was used to pretreat fumaric acid wastewater,and the removal rate of ammonia nitrogen was mainly studied. Based on the BBD response surface method,the individual and interaction of voltage,reaction time and initial pH were explored,and a mathematical model of ammonia nitrogen removal rate was established. The results show that the significant order of influence factors is voltage>reaction time>initial pH,and there is a certain interaction among the three,but it is not significant. A satisfactory prediction quadratic polynomial equation was derived by response surface methodology. The maximum removal rate of ammonia nitrogen is predicted to be 88.7%. The optimum operating conditions are:The voltage is 28.41 V,the reaction time is 87.27 min,and the pH is 4.55. Using the above best conditions,the ammonia nitrogen removal rate of 87.6% was obtained,which is consistent with the predicted value of 1.2%.
