厌氧-A/O接触氧化工艺应用于丝厂高浓度有机废水的处理。采用不同废水分质处理的原则，节省了污水处理投资和运行费用，实现了厌氧过程三阶段的分离，提高了厌氧处理效果，减少了剩余污泥，降低了处理费用，增强了工艺可应用性。经过两年多的运行实践表明，该工艺具有运行稳定，处理效果好，能完全实现达标排放，且剩余污泥量少的特点，值得在其他同类型废水处理中借鉴。

Anaerobic contacted oxidation process is applied to treat silk mill wastewater containing lots of organic mat ter.the results through more than two years running, indicate that this process has such properties as high running stability, excellent treat ment effect, and the leastresidual sludge occurence.
