沉淀—吸附处理双氯灭痛高浓度有机废水的工艺研究

Treatment of high concentration organic wastewater from diclofenac sodium production process with precipitation-adsorption technology

介绍了用沉淀—吸附法处理双氯灭痛高浓度有机废水的工艺。先用废盐酸将废水的 p H调节到 4,沉淀、过滤 ,然后将滤液依次经过炉渣、活性炭串级吸附 ,处理后的废水 CODcr、 p H、 SS均达到 GB8978-

s:The high concentration organic wastewater from diclofenac sodium production process was treated by precipitationadsorption technology.At first,the wastewater was regulated to pH=4 with waste hydrochloric acid,some pollutants were precipitated and filtered.Then the filtered wastewater was adsorbed by slag and activated carbon in order.Finally,CODcr,pH and SS of the effluent could reach the discharge standard of China.
