摘要
采用 2 0 0 L/ d CWO小型工业试验装置对高浓度焦化废水进行处理试验研究 ,结果表明 CWO技术装置对处理高浓度焦化废水 (CODCr,10 0 0 0～ 130 0 0 mg/ L、NH3- N12 0 0～ 2 10 0 mg/ L)具有良好的技术可行性 ,废水经处理后 (催化反应时间 30～ 4 5 min) ,废水中 CODCr、NH3- N的去除率即可达到 99%以上 ,处理水中的 CODCr、NH3- N浓度均可达到国家排放标准 (CODCr<10 0 mg/ L、NH3- N<15 mg/ L ) ,且废水的脱色、除臭效果明显。对于不同浓度焦化废水的处理 ,CWO技术及装置表现出了很好的适应性。国产化 2 0 m3/ d CWO工业装置对焦化废水的连续处理运行表明 ,CWO技术在国内已达到工业化应用水平 ,并具有较好的经济性。
By using the 200L/d CWO tester,the high concentrated wastewater of cokes making was treated in this test research.In the research the CWO technology displayed its good technique applicability for treating the wastewater(CODcr 10000～13000mg/L,NH 3-N 1200～2100mg/L).After the treatment by using the CWO test plant (catalytic reaction time 30～45min),more than 99% of CODcr and NH 3-N could be removed from the wastewater.The treated wastewater could meet the emission standard (CODcr<100mg/L,NH 3-N<15mg/L).And the wastewater could be decolored and deodorized effectively in the CWO treatment process.The CWO technology has a good adaptability for treating the wastewater of cokes making with different concentrations.The 20m 3/d CWO industrial installation was run continuously and stably for treating the wastewater of cokes making with lower cost in this research.The research result indicated that the application research of CWO technologh had reached at the level of industrialization use in China.
