摘要
海洋中有机质、重金属、氮、磷、硫化物等含量的增加加重了沉积环境的污染。本文分析了海水养殖沉积环境中硫化物、有机质、重金属的污染状况并提出相应修复的方法。去除硫化物是修复海水养殖沉积环境的重要途径,详述了去除硫化物的方法———生物修复法和沉淀法,并提出含铁的氧化物、氢氧化物、高铁酸盐等辅以絮凝剂的沉降法是养殖沉积环境修复的理想方法。
The contents of organic matters, heavy metals, nitrogen, phosphorus, sulfide, et al. in marine areas are becoming higher, which enhance the pollution of sediment environment. In this article, the pollution conditions of sulfide, organic matters, and heavy metals in sediment environment of marine aquaculture and the responding removal methods are described. The sulfide pollution is very important and the concentration of AVS determines the benthos toxicity of heavy metals. So removing sulfide is an important way of remedying the sediment environment of marine aquaculture. The methods of bioremediation and deposition are deseribed in detail. Depositing iron compounds are considered as an ideal method.
