| 摘 要： | 在近海集约化养殖过程中,水动力条件的改变、大量饵料的投放以及强烈的生物沉降导致底质生境有机污染严重,形成大面积缺氧区。在此环境中,含硫蛋白质降解和硫酸盐异化还原导致硫化物大量产生并扩散,成为海水养殖生态系统中危害程度仅次于氨氮的污染物,应该引起人们的足够重视。本文分析了近海养殖环境中硫化物产生的驱动力、硫化物在沉积物-水界面的扩散、硫化物污染控制技术及其优缺点,指出以铁氧化物为基础的化学控制技术和以硫氧化菌为基础的生物控制技术在硫化物污染控制持久性、可靠性等方面具有明显优势,在实际工程中具有应用潜力。

| Abstract: | In the process of intensive aquaculture in the coastal area,the change of hydrodynamic conditions,the feeding of a large number of bait and the strong biological sedimentation lead to the serious organic pollution of the bottom habitat,forming a large area of anoxic area.In this environment,sulfur-containing protein degradation and sulfate dissimilation reduction result in a large sulfide production and diffusion,and sulfide becomes the second most harmful pollutant in mariculture ecosystem,which should be paid enough attention to.In this paper,the driving force of sulfide production,the diffusion of sulfide at the sediment water interface,the control technology of sulfide pollution and their advantages and disadvantages were reviewed.Considering the durability and reliability,this paper pointed out that the chemical control technologies based on granular iron oxide and the biological control technologies based on sulfur oxidizing bacteria showed obvious advantages in controlling the pollution. |
