珠三角河道底泥资源化利用探讨
|
摘要
污染底泥的处理处置是河道治理的重要内容,然而传统填埋处置方式不利于生态保护和可持续发展。文章详细总结了珠三角地区河涌底泥的营养成分、矿物组分、污染情况等方面的研究成果,分析了各因素对底泥处理处置方案的影响,研究发现底泥污染程度及污染物毒性限制了其作为土地利用的途径;对污染程度较重的底泥,需采用严格的修复技术措施处理后,方能进行工程化应用;矿物组分决定了底泥是否适用于建材生产。结合实际案例,分析了常见底泥处理处置技术的优缺点及其在珠三角区域的适用性与市场前景,并对珠三角底泥资源化应用途径和方式提出了建议。
The treatment and disposal of contaminated sediment is an important part of river regulation, however, the tradi-tional landfill disposal methods are not conducive to ecological protection and sustainable development. In this paper, the re-search results of the nutrient composition, mineral composition and pollution of the sediment in the Pearl River Delta are sum-marized in detail, and the influence of various factors on the treatment and disposal scheme of sediment is analyzed. It indi-cates that the degree of sediment pollution and the toxicity of the pollutants limit the way of land use, the heavy polluted sed-iment can be used as projects materials only after strict remediation technologies were carried out to deal with pollutants, and mineral composition determines whether the sediment is suitable for building materials. Based on the practical cases, the ad-vantages and disadvantages of common technologies, its applicability and market prospect in the Pearl River Delta region are analyzed, and the proposals were made on the resourced utilization of treated sediment in the Pearl River Delta.
