摘要
根据2010～2011年清水江流域6个断面不同季节氟化物含量的监测数据分析,结果表明:氟化物含量最大值出现在重安江断面,为8.61mg/L,常年总体变化趋势为枯水期>平水期>丰水期。利用SPSS19.0统计分析软件中Pearson检验法对各监测数据进行分析,各监测断面间具有显著正相关,充分说明了各监测点的实际联系,同时重安江断面显著相关值最大,可以初步断定重安江断面上游为污染源。为更好地防治氟化物对清水江流域的影响,通过对清水江流域跟踪监测及氟化物含量变化分析,结合实际情况制定清水江流域氟化物污染防治对策,为环保部门监管排污企业提供参考和借鉴。
Fluoride concentrations in 6 sections of Qingshui River Basin in different seasons were traced and monitored from 2010 to 2011, and the result revealed that, 1 ） The maximum was observed at the section of Chongan River as 8.61 mg/L, and seasonal trends with the variation in the range of （ 1.97 ± 1.73 ） mg/L, was ranked as ： Cdry 〉 Cavatage 〉 Cwei ,2 ） Monitoring data were analyzed by SPSS 19.0 and showed that there was a sisnificant positive correlation between each monitoring.section except U - 1. In these related sections, Chongan River had the largest correlation coefficie6t that indicated it is the main pollution source of fluoride. Finally this paper brought out the countermeasures for fluoride pollution based on the above interpretation and provided valuable reference for environmental inspection sectors in managing poUution emission industries.
