摘要:
为提高镀镍废水中次/亚磷酸盐到正磷酸盐的氧化率，利用响应面法对Fenton反应条件进行优化，再加入CaO进行化学除磷。结果表明，响应面法建立了非正磷酸盐氧化率与初始pH、Fe2+投加量、n（H2O2）∶n（Fe2+）的二次多项式模型，具有高度显著性。最佳反应条件为初始pH为3.7，Fe2+投加量为16.2 mmol/L，n（H2O2）∶n（Fe2+）为4时，预测氧化率为99.72%，与实际实验结果偏差仅为0.6%。利用CaO进行化学除磷，当废水的pH为中性时，出水总磷能够达到《污水综合排放标准》（GB8978—1996）的一级排放标准。
Abstract:
In order to improve the oxidation rate of hypophosphite and phosphite to orthophosphate in nickel plating wastewater, response surface methodology was used to optimize the Fenton reaction conditions, and then CaO was added for chemical phosphorus removal. The results show that the quadratic polynomial model of oxidation rate of non-orthophosphate with the initial pH, Fe2+ dosage, n（H2O2）∶n（Fe2+） is established by response surface method, which is highly significant. The optimum reaction conditions are 3.7 for the initial pH, 16.2 mmol/L for the Fe2+ dosage, and 4 for n（H2O2）∶n（Fe2+）. Under this condition, the predicted oxidation rate is 99.72%, and the deviation is only 0.6% from the actual experimental results. Using CaO for chemical phosphorus removal, when the pH in the wastewater is neutral, the total phosphorus in effluent can meet the first class discharge standard of Integrated Sewage Discharge Standard （GB8978—1996）.
