摘要

摘要: Fe和Mn是氧化还原敏感元素，厌氧与有氧均会造成Fe、Mn及硫化物沉积物释放和形态转化，导致水质恶化，目前鲜有研究将泛黑与Fe、Mn及硫化物迁移规律耦合。选取广西壮族自治区南宁天雹水库为研究对象，于2018年3-12月对水库不同深度进行采样，分析水库水质的季节性变化特征以及对Fe、Mn、硫化物迁移转化规律的影响。结果表明：热分层结构主要受气温变化影响，分层期温跃层形成导致垂向理化性质差异，形成底部低温厌氧环境。独特的红土壤结构使Fe和Mn具有更强的内源释放能力，在降雨冲刷及长期厌氧影响下Fe和Mn底层大量释放，浓度达到0.76，1.47 mg/L，高浓度Fe抑制了硫化物释放（0.005 mg/L）。泛黑期分层破坏引发垂向对流混合，复氧使Fe、Mn及硫化物形态转化，向上迁移同步产生FeS、MnS等致黑物质，触发表层产生泛黑现象，后续开展黑水触发机制与物质甄别研究是解决泛黑问题的关键。

Abstract: Iron and manganese are redox sensitive elements. Anaerobic and aerobic process can cause the release and morphological transformation of iron, manganese and sulfide sediments, resulting in the deterioration of water quality. At present, few studies combined black water of reservoir with migration of iron, manganese and sulfide. In order to explore the frequent blackening phenomenon of reservoirs in the southern water source area, we selected the Tianbao reservoir in Nanning as the research object, and collected samples from different depths of the reservoir from March 2018 to December 2018, to analyze the seasonal variation characteristics of water quality of the reservoir and the influence on the migration and transformation of iron, manganese and sulfide. The results showed that the thermal stratification structure was mainly affected by the temperature change. The formation of thermocline in stratification period led to the vertical physical and chemical properties difference, which formed the low temperature anaerobic environment at the bottom. And the unique red soil structure made iron and manganese have stronger endogenous release capacity. Under the influence of rainfall erosion and long-term anaerobic situation, the iron and manganese layer released in large quantities (0.76 mg/L and 1.47 mg/L), the sulfide release was inhibited by high concentration iron (0.005 mg/L). During the blackening period, the stratification failure caused vertical convective mixing. Reoxygenation transformed the forms of iron, manganese and sulfide, and simultaneously migration upward produced FES, MNS and other blackening substances, which triggered the surface blackening phenomenon. The key to solve the problem of blackening was to carry out researches on triggering mechanism and substance screening of black water.
