通过实验室内海水浸放疏浚沉积物的静态和动态模拟实验,探讨了锦州港沉积底泥中重金属的解吸和吸附.用葫芦岛市五里河沉积物中的金属做了对比实验,进一步研究了海洋沉积物-海水间重金属交换作用,在海流的运动下,重金属对上覆水释放和构成对海洋环境的影响.港区疏浚物溶出过程中水体的极限释放浓度和平衡后浓度均未超过一类海水标准,没有造成对海水的污染问题,而五里河沉积物已形成对海水的二次污染,因此已污染的疏浚物在海洋倾倒时会造成新的环境污染问题.
The desorption and adsorption of heavy metals in Sediment sediments of Jinzhou Port are discussed by static and dynamic simulation experiments of dredged sediments immersed in seawater by laboratory.Compared with the metals in the sediments of Wuli River in Huludao City, Under the action of ocean currents, heavy metal exchange between sea sediments and seawater affected the release of heavy metals and the effect of heavy metals on the marine environment. The limit release concentration and post-equilibrium concentration of dredged materials in the port area did not exceed one Seawater standards have not caused the problem of seawater pollution, whereas the Wuli River sediments have formed secondary pollution to the seawater, so that the contaminated dredged materials will cause new environmental pollution problems when the ocean is dumped.
