摘　　要：介绍了两级接触氧化法、接触氧化+活性污泥法、兼氧-好氧生物接触法以及高浓度活性污泥法等几种工艺组合处理某染料废水的处理效果。着重考查了各工艺组合在各自适宜条件下对染料废水CODCr的去除率及其稳定性。结果表明,CODCr为2000mg/L左右的染料废水经高浓度活性污泥法处理后,去除率可以稳定保持在85%以上且污泥持续保持良好状态。Effects of several technics conbinations,including two-stage contact oxidation process, contact oxidationactivated sludge process,facuhative-aerobic bio-contact process and high concentration activated slude process,for dye-wastewater treatment were introduced. It was stressed to study the CODCr removal rate of the dye-wastewater by each technics con-bination in its condign condition and its stability. The results showed that while the CODCr of influent was about 2000mg/L,the removal rate of CODCr kept above 85% after the dye-wastewater was treated by high concentration activated sludge , activated sludge also went on well.
