摘要
针对广西水库周围大量种植速生桉后,水库水质恶化现象,通过速生桉导致水体黑臭的室内模拟实验验证致黑臭物质之间的相互作用及其影响因素。通过设置桉树叶和非桉树叶在不同条件下的室内模拟实验,测定桉树叶和非桉树叶腐解过程中水体pH值,DO,Fe,Mn,硫化物,单宁酸以及DOC随时间的变化规律,结果表明桉树叶腐解过程中释放单宁酸,溶解性有机碳(DOC),Fe,Mn含量明显高于非桉树叶。水环境中硫化物主要来源于底泥,单宁酸、Fe、硫化物、Mn之间的相互作用导致水体黑臭。
Aiming at the deterioration of water quality after a large number eucalyptus planted around the Guangxi Reservoir, verified the interaction between black odorous substances and its influencing factors through the indoor simulation experiment.The indoor simulation experiment of Eucalyptus leaves and non eucalyptus leaves under different conditions was carried out, the changes of pH, DO, Fe, Mn, sulfide, tannic acid and DOC in the decomposition process of Eucalyptus and non-eucalyptus leaves were measured. The results showed that the contents of tannic acid, DOC, Fe and Mn in the decomposition process of Eucalyptus leaves were significantly higher than those in non-eucalyptus leaves.Sulfides in the aquatic environment mainly come from the sediment, tannic acid, sulfide, iron and manganese, which leads to the black smell of the water.
