摘　　要：结合国内外的研究,对温度、pH值、溶解氧等环境因素影响污染物释放的机制进行了综述。其中,温度的升高会促进底泥中氮磷的释放;随着溶解氧含量的增多,污染物越发不易释放;但pH值对底泥中的氮磷以及重金属的释放影响规律则各有不同。此外,结合国内外工程案例及试验研究,对污染底泥的治理技术进行了总结,分析了物理、化学和生物处理方法的利弊。联合处理方法则综合了多种方法的优点,具有良好的应用前景。Combined with research at home and abroad, this paper summarized that how environmental factors like temperature,pH and dissolved oxygen,influenced the release of sediment pollutants. In brief,the rise of temperature will accelerate the release of nitrogen and phosphorus in the sediment; and along with the increase in dissolved oxygen content,however,the pollutants become more difficult to release; while pH had different effect on release of nitrogen,phosphorus and heavy metals in the sediment. Besides,combined with the engineering cases and experimental research in China and oversea,the paper concluded contaminated sediment disposal technologies and analyzed the advantages and disadvantages about physical,chemical and biological technologies. The combined treatment synthesized characteristics of these three technologies,it would have more application prospects in the future.
