摘要
利用引进的CWO处理技术及其 2 0 0L/d小型工业试验装置 ,对我国焦化、造纸、生物制药等十多种行业的高浓度工业有机废水进行处理试验研究 ,结果表明CWO技术及装置对处理我国高浓度工业有机废水具有良好的适用性。在昆明自主设计、制造、集成建设和运行了一套 2 0m3/d工业应用装置 ,完成了对该技术的国产化研究与示范工程。该工业化应用装置对造纸黑液、焦化废水等两种高浓度生化难降解工业有机废水具有良好的净化处理性能 ,废水中的CODCr,NH3-N等的去除率均达 99%以上 ,可以使废水经处理后连续稳定地达标排放 。
By using the introduced CWO technology and its 200 L/d plant, more than 10 kinds of industrial wastewaters with high concentration in China, such as the waste liquor of coking, the black liquor of paper making, the waste mother liquor of bio-pharmacy and so on, were treated in this research. The results showed that the CWO technology and its equipment had a good applicability for treating the industrial wastewaters with high concentration in China. One set of CWO-20 m 3/d industrial plant, as a demonstration engineering installation of CWO technology, was independently designed, made and operated in Kunming city. During the running test, the CWO-20 m 3/d plant displayed a favorable treatment capability for the bio-degradedly difficult industrial wastewaters with high concentration. For the treatment of the waste liquor from coking and the black liquor of paper making, more than 99 % of COD Cr and NH 3-N in the wastewater could be removed. The CWO-20 m 3/d plant could be run continuously and stably. The treated wastewater could meet the discharge standard and the treatment process with CWO technology showed up a good economic advantage.
