| 中文摘要: |
| 以深圳市前海片区代表性河道黑臭底泥为研究对象，对其pH值、含水率、有机质、氮磷含量、重金属含量及粒径进行分析。结果表明，黑臭底泥主要为呈碱性的无机砂质成分，有机质含量低，重金属含量虽高但分布稳定。根据其特性，最终确定其主要处置方式为疏浚后机械脱水。 |
| 英文摘要: |
| In this paper, taking the representative sediments from black odor river in Qianhai district of Shenzhen as the research objects, pH value, moisture content, organic matter content, mass fraction of nitrogen and phosphorus, concentrations of heavy metals and particle size distribution of the sediments were determined. The results indicated that the black odor sediments were mainly composed of alkaline inorganic sand containing a few amount of organic matters and lots of heavy metals which were in stable distribution. According to the properties of the sediment, the final treatment way was mechanical dewatering after dredging. |
