| 摘 要： | 采用中和-膜过滤法处理酸性含氟废水时,当中和池的pH在6～9范围时,处理后废水中的氟离子和金属离子不能稳定控制在上海市污水综合排放标准以内.经研究分析发现,提高中和池的pH在10.5时,可提高废水中氟离子及金属离子的去除率.在排放前回调pH,可使废水水质稳定达标排放.

| Abstract: | A neutralization-membrane filtration process has been used to treat the fluoride-bearing acidic wastewater.The result shows that when the pH of the fluid in the neutralizing tank is ranging from 6 to 9,the concentration of the discharged fluoride ions and the metallic ions in the wastewater can not steadily meet the discharge standard of Shanghai.The tests shows that the removal rates of fluoride ions and metallic ions in the wastewater are raised when the pH reaches 10.5 or above in the neutralization tank.Before discharging the wastewater the pH should be readjusted to 7 to assure each pollutant factors to steadily meet the discharge standard. |
