中文摘要:

根据2012年11月至2013年9月的9次监测数据,分析了淮南潘集开放型和封闭型采煤沉陷区地表水中氮、磷时空分布特征及污染源;通过相关性分析揭示了同类水体内氮、磷之间的响应关系和运移特征;通过各形态氮、磷比率分析了两类水体中氮、磷组成.结果表明,NH3-N(氨氮)年内时间差异性较小,整体呈KB(开放型地表水)〉FB(封闭型地表水),最大值分别为0.621 mg·L-1(6月)和0.813 mg·L-1(6月);NO-2-N(亚硝酸氮)时空差异性均较小,NO-3-N(硝酸盐氮)和TN(总氮)年内时间差异性较大,空间差异性较小,整体上均呈FB〉KB.KB与FB内NO-2-N最大值分别为0.0485 mg·L-1(6月)和0.0532 mg·L-1(6月),NO-3-N(硝酸盐氮)最大值分别为0.635 mg·L-1(11月)和0.623 mg·L-1(4月),TN最大值分别为2.295 mg·L-1(11月)和2.261 mg·L-1(1月).PO3-4和DTP(溶解性总磷)含量基本呈KB〉FB,两形态磷在KB内的最大值分别为0.174 mg·L-1(11月)和0.055 mg·L-1(11月),FB内最大值分别为0.0298 mg·L-1(6月)和0.0391 mg·L-1(5月);TP(总磷)基本呈KB〈FB,最大值分别为0.1141 mg·L-1(8月)和0.197 mg·L-1(5月).氮、磷主要污染源为降雨地表径流、底泥内源释放及人为活动等;同类沉陷区地表水内各形态氮、磷之间存在不同程度的相关性;两类水体内氮、磷组成存在一定差异性,开放型采煤沉陷区地表水更易发生富营养化现象.

英文摘要:

Based on nine sets of monitoring data from November 2012 to September 2013,this paper analyzed the temporal and spatial distribution characteristics and pollution source in surface water of open and closed coal mine subsidence area in Panji of Huainan. Correlation analysis revealed the various response relationship and migration characteristics between nitrogen and phosphorus in the same water body. Compositions of nitrogen and phosphorus in the two types of water bodies were analyzed based on its ratio between various forms. Results showed that the temporal difference of NH3-N is small. As a whole,KB( open surface water) was larger than FB( closed surface water),with the maxima respectively 0. 621 mg·L-1( June) and 0. 813 mg·L-1( June). The temporal and spatial differences of NO-2-N were smaller on average. The temporal differences of NO-3-N and TN were bigger in the whole year,while the spatial were smaller and the whole presentation was FBKB. Between KB and FB,the maxima of NO-2-N were 0. 0485 mg·L-1( June),0. 0523 mg·L-1( June),the maxima of NO-3-N were 0. 635 mg·L-1( November),0. 623 mg·L-1( April) and themaxima of TN were 2. 295 mg·L-1( November),2.261 mg·L-1( January). KB was larger than FB in terms of the content of PO3-4and DTP,the maxima of two phosphorus forms above in KB were0. 1738 mg·L-1( November),0.055 mg·L-1( November) and the maxima in FB were 0.0298 mg·L-1( June),0.0391 mg·L-1( May). The basic presentation of TP was KB〈FB and the maxima were0. 1141 mg·L-1( August),0. 197 mg·L-1( May). The primary pollution sources of nitrogen and phosphorus were rainfall surface runoff, sediment endogenous release, human activities, etc.Correlation of different degrees was found between nitrogen and phosphorus in the similar subsidence surface water. And certain differences existed as to the compositions of nitrogen and phosphorus in the two water bodies. Open coal mine subsidence surface water was prone to eutrophication phenomenon
