Distribution of phosphorus fractions and bio-available phosphorus forms and their relationship in the sediments from different regions of Lake Taihu

Wang Qi; Jiang Xia; Jin Xiangcan; Xu Yuhui

Concentrations of total phosphorus (TP) , their fractions and the bio-available phosphorus (BAP) in the surface sediments from three different regions of Lake Taihu are investigated. In addition, the potential release capacity of P from the surface sediment and their sources were discussed. The concentrations of TP, P fractions and BAP are coincided very well with their trophic states. The concentrations of organic P in the sediments have a good relationship with organic matter and moisture content. BAP is mainly from Fe bound P (Fe-P) and Ca bound P (Ca-P) , which show the highest potential risk of release.

采用三维荧光光谱-平行因子法(EEMs-PARAFAC)分析太湖五里湖水体悬浮物中水溶性有机质(WSOM)的荧光光谱特征,研究其组分类型、分布规律以及来源,进一步探讨悬浮物中水溶性有机氮和无机氮含量与WSOM荧光组分之间的关系.结果表明,悬浮物中WSOM荧光组分主要由2个类腐殖质(C1、C2)和1个类色氨酸类蛋白质(C3)组成.总荧光强度在57.56~200.01 R.U./g之间,平均为115.42 R.U./g,其中C1、C2、C3的相对比例分别为35.55%、34.05%和30.40%;空间上由西向东逐渐增强,东五里湖高于西五里湖,沿岸区高于湖心区.荧光指数和生物源指数变化范围分别在1.48~2.34和0.65~0.87之间,反映了悬浮物中WSOM主要来源于微生物、藻类的自生生物源.多元回归统计分析结果表明,悬浮物WSOM与氮元素的迁移转化密切相关,且有机氮与WSOM荧光组分的相关系数大于无机氮.

污染底泥环保疏浚工程的理念·应用条件·关键问题

姜霞; Jiang Xia; 王书航; Wang Shuhang; 张晴波; Zhang Qingbo; 王雯雯; Wang Wenwen

污染底泥是水体最主要的内源,存在污染物二次释放的风险,而环保疏浚可以有效地清除污染底泥、降低内源污染负荷及其释放风险,因此近年来该技术在水环境治理中得到广泛的应用.环保疏浚的主要目的是有效清除河流、湖泊(水库)水体污染底泥中累积的污染物,并对浚后污泥进行安全处理处置,为污染河流、湖泊(水库)水质改善与生态修复发挥工程作用.作为湖泊、河流水污染综合治理技术体系的重要组成部分,环保疏浚是生态环境工程技术之一,也是湖泊河流水污染治理的重要手段;但底泥疏浚同时也存在疏浚效果不理想、可能造成原位扰动与异地污染、改变水生态系统的结构与功能等生态风险.研究显示,未来环保疏浚的主要发展方向应包括:① 基于调查评估基础上的污染底泥分区、分类环保疏浚及处理处置研究;② 污染底泥环保疏浚与区域生态修复一体化设计研究;③ 污染底泥环保疏浚-浚后干化-处理处置-资源化集成技术研究;④ 污染底泥环保疏浚、处理和资源化全过程监管评估技术研究.
