The degradation of chlorinated organic pollutants is an important subject of water pollution control. Currently, there are three major degradation methods of chlorinated organic pollutants: physical method, chemical method and biodegradation method. Referring to the relative research literature in recent years, the pa-per reviews the reaction mechanism of varied degradation techniques and the progress of their current research. Meanwhile, the paper sorts out the problems and defects in the practical application of diversified degradation techniques and ultimately puts forward the outlook of the research trend in the future.%有机氯污染物的降解是水污染控制的一项重要课题。目前，有机氯污染废水降解方法主要有物理降解法、生物降解法以及化学降解法等。综述各种降解方法的原理以及目前国内外研究者对该技术的研究进展，同时指出各个降解技术研究在实际应用中所存在的问题和不足，并对未来有机氯污染废水降解技术的研究提出了相应的展望。
