摘　　要：采用预处理-水解酸化-生物接触氧化相结合的处理工艺处理含氟代有机化合物废水。研究结果表明,水解酸化可将含氟废水的B/C比由0.258提高到0.396;在一定浓度范围内通过物化预处理及生化处理可以脱除氟代有机化合物中的氟原子,使该有机物成为可供微生物利用的基质。含氟废水经该工艺处理后,出水中BOD5为7.5mg/L,CODcr为75mg/L,氨氮未检出,总磷小于1mg/L,氟离子浓度为8.6mg/L。Study on the treatment of fluorinincluded wastewater with pretreatmenthydrolytic acidificationbiological contact oxidation progress has been conducted. Research result shows that the biodegradability(BOD5/CODcr) of fluorinincluded wastewater can be raised from 0.258 to 0.396 by hydrolytic acidification; the fluorin in the fluorine compounds is removed after physicalchemical pretreatment and biochemical process in certain range, and hence be changed into the substrate that can be used by microorganism. By applying hydrolytic acidificationbiological contact oxidation, the national second outflow standard can be reached in the effluent, result shows that BOD5 is about 7.5mg/L, CODcr is about 75mg/L,ammonium can't be tested out, TP is less than 1mg/L, and the contration of fluorin is about 8.6mg/L.
