摘要
2011年7月~2012年4月对典型入河河流——太滆运河干流10个断面及33个支浜总氮含量共进行了3次监测,并提出了太滆运河水环境综合整治措施。监测结果表明,太滆运河干流和支浜所有监测点总氮均超过了《地面水环境质量标准》(GB3838-2002)V类水质标准。单因素分析表明,春、夏、冬季太滆运河支浜和干流单因子污染指数Ij值都达到了2左右,干流Ij最大值位于分水大桥,为5.15,支浜Ij最大值位于小桥浜,为4.24。3次调查总氮的超标率都高达100%,太滆运河及周围河网支浜总氮污染严重,主要是由于受太滆运河两岸陆源污染及客水影响较大。
The water quality levels of 10 sections of Taige Canal and 33 tributaries were surveyed for 3 times during July 2011 to April 2012,the comprehensive control countermeasures for water environment in Taige Canal were put forward.The monitoring results showed that,TN of canal and tributaries all beyond Surface Water Environment Quality Standard(GB3838-2002) V for standard of water.The single factor analysis showed that,the Ij value is up to 2,the maximum Ij value is located in Fenshui Bridge in mainstream water,reached 5.15,and the maximum Ij value,to 4.24 in tributary by single factor analysis.Three times survey of total nitrogen all were up to 100%.The TN pollution situation of Taige Canal and tributaries is rather serious,mainly affected by land-source pollution and vip water.
