污染水体底泥土地利用影响和风险控制

The Influences and Impacts of Polluted Sediment Utilization

受污染底泥的资源化利用,是解决环境问题的有效途径,但其利用过程中的风险和影响不容忽视。其风险和影响主要在于重金属、有毒有害物质及营养盐的扩散对水体、土壤及动植物等的影响。在进行有效的评估和预处理后,底泥的资源化利用基本不受影响。

The polluted sediment utilization is one of the most environmental friendly strategies. Given the risks of leakage and transfer of pollutants in the sediment to the surrounding environment, there were some negative influences of the polluted sediments utilization. In this review, these influences were thoroughly discussed based on the mechanism of the reactions in the sediment. And the control strategieswere addressed on these reactions and impacts.
