为了使焦化废水 NH3-N 能够达标排放，采用气浮法＋改良式序列间歇反应器(DAF＋MSBR)联合法处理榆林某焦化厂焦化废水。结果表明，进水 CODcr 平均质量浓度为1490 mg / L，NH3-N 平均质量浓度为200 mg / L，挥发酚平均质量浓度为176 mg / L，CN 平均质量浓度为17 mg / L，SS 平均质量浓度为580 mg / L，DAF 处理时间3 h，MSBR 处理时间9 h。经 DAF＋MSBR 法处理后，出水 CODcr浓度为74.3 mg / L，NH3-N 为10 mg / L，挥发酚为0.25 mg / L，CN 为0.09 mg / L，SS 为30 mg / L，去除率分别为93.8％、95％、99.8％、99.4％、95％，达到?炼焦化学工业污染物排放标准?排放标准。
為瞭使焦化廢水 NH3-N 能夠達標排放，採用氣浮法＋改良式序列間歇反應器(DAF＋MSBR)聯閤法處理榆林某焦化廠焦化廢水。結果錶明，進水 CODcr 平均質量濃度為1490 mg / L，NH3-N 平均質量濃度為200 mg / L，揮髮酚平均質量濃度為176 mg / L，CN 平均質量濃度為17 mg / L，SS 平均質量濃度為580 mg / L，DAF 處理時間3 h，MSBR 處理時間9 h。經 DAF＋MSBR 法處理後，齣水 CODcr濃度為74.3 mg / L，NH3-N 為10 mg / L，揮髮酚為0.25 mg / L，CN 為0.09 mg / L，SS 為30 mg / L，去除率分彆為93.8％、95％、99.8％、99.4％、95％，達到?煉焦化學工業汙染物排放標準?排放標準。

In order to make the NH3 -N content in coking waste water meet the discharge standards,taking the waste water in a coking plant in Yulin as research object,the author studied the treatment effects of DAF(dissolved air flotation) + MSBR(modified sequencing batch reactor) combined process.The results showed that the average concentration of influent CODcr,NH3 -N,volatile phenol,CN,SS were 1490 mg/ L,200 mg/ L,176 mg/ L,CN average concentration of 17 mg/ L,580 mg/ L.The processing time of the DAF and MSBR was 3 and 9 hours.After treated by the DAF + MSBR process,the average concentration of influent CODcr,NH3 -N,volatile phenol,CN,SS were 74.3 mg/ L,10 mg/ L,0.25 mg/ L,0.09 mg/ L,30 mg/ L,so the removal rate was 93.8%,95%,99.8%,99.4% and 94.8%.The pollu-tant in waste water met the Coking Chemical Industry Emission Standards.
