宝鸡市城市污水中主要污染物数理统计分析

Analysis on Mathematical Statistics of Main Pollutants in Urban Sewage of Baoji City

本文运用数理统计,对宝鸡市金信安污水处理厂两年监测数据中主要污染物COD、BOD5、总氮(TN)、氨氮、总磷(TP)、悬浮物(SS)相关性分析和显著性检验。相关性分析显示COD和BOD5,总氮和氨氮存在正相关关系;显著性检验显示BOD在季节之间存在显著性差异,其余五个监测因子在季节之间不存在显著性差异。

Using mathematical statistics, in the two years of monitoring data of Baoji Kingsum sewage treatment plant main pollutant COD, BODs, total nitrogen （TN）, ammonia nitrogen, total phosphorus （TP）, suspended solids （SS） correlation analysis and significance test. Correlation analysis showed that COD and BOD5, total nitrogen and ammonia nitrogen exist positive correlation; Significance test showed that BOD in the season that there was a significant difference between the remaining five monitoring factor, there is no significant difference between the seasons.
