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 CODcr 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 shown up a good economic advantage. 关 键 词：高浓度工业废水 湿式催化氧化法 废水处理 化学需氧量 氮
