植物法修复污染河道底泥

近年来,污染河道底泥修复越来受到关注。植物法具有其成本低、效果好、不易坏生态环境和不产生二次污染等优点,成为当今污染河道底泥的研究重点和热点。针对不同类型污染底泥,总结和梳理了N、P营养盐污染底泥,有机物污染底泥和重金属污染底泥的修复特点,实际应用中,需因地制宜,兼顾多方面因素,选择合适的植物,并提出今后需要重点研究的方向。

Phytoremediation of Polluted River Sediment

In recent years, the remediation of polluted river sediment is getting more attention. The plant method has the advantages of low cost, good effect, less damage to the ecological environment and no secondary pollution, which becomes the research focus and hotspot for polluted river sediment today. Aiming at the different types of polluted sediment, the remediation characteristics of N and P nutrient contaminated sediment, organic matter contaminated sediment and heavy metal contaminated sediment are summarized and sorted out. In practical applications, it is necessary to adapt to local conditions, take into account multiple factors, select suitable plants and propose the directions required to be studied in the future.
