| 中文摘要 |
| 为了解大辽河主要污染源包括上游浑河、 太子河及其支流海城河和沿程排污口等对大辽河营养盐输入特征,通过国标测定方法,于2013年7月对13个采样点各形态N、 P质量浓度的变化和百分含量进行研究. 结果表明,大辽河上游来水中浑河DON、 太子河NO3--N、 海城河NH4+-N、 PO43--P、 DOP质量浓度较高,与地表水环境质量标准(GB 3838-2002)相比,除太子河TP表现为Ⅳ类水质外,其余TN、 TP均表现为劣Ⅴ类水质,浑河水体中N形态以DON为主,而太子河和海城河以NO3--N为主,除海城河水体P形态以DOP为主外,其余均以TPP为主. 主要排污口中TN均表现为劣Ⅴ类水质,TP则为Ⅳ至劣Ⅴ类不等,其中纱厂潮沟、 港监潮沟这2个排污口NH4+-N、 TN和TP质量浓度均最高,但主要排污口水体N形态均以DIN为主,水体P形态则表现不一. 而大辽河TN、 TP质量浓度较高,超过地表水环境质量标准的Ⅴ类限值,且NO3--N和TPP分别是其主要形态. 总体上,通过对大辽河上游来水、 排污口与大辽河干流营养盐分析表明,大辽河营养盐受其沿岸主要排污口的影响较为显著,主要排污口污水排放对大辽河水质的影响不容忽视. |
| 英文摘要 |
| A total of 13 surface water samples were collected from sewage outfalls and 3 main tributaries (Hunhe River, Taizi River and Haicheng River) of the Daliao River to clarify the pollution characteristics of various species of nitrogen and phosphorus in July 2013, respectively. The results showed that the concentrations of DON in the Hunhe River, NO3--N in the Taizi River, NH4+-N, PO43--P and DOP in the Haicheng River were higher than others. In water samples from the 3 main tributaries of the Daliao River, the TN and TP contents were above the national environmental quality standards for surface water (GB 3838-2002, grade Ⅴ) except for the TP that was classified as grade Ⅳ in the Taizi River. The percentages of various N species showed that NO3--N was the major N species in the Taizi River and Haicheng River, meanwhile DON was the major N species in the Hunhe River. The percentages of various P species showed that TPP was the major P species in the Hunhe River and Taizi River, and DOP was the major P species in the Haicheng River. TN content was above the national environmental quality standards for surface water (GB 3838-2002, grade Ⅴ) in sewage outfalls. But TP content was classified as grade Ⅳ to above grade Ⅴ. And the concentrations of NH4+-N, TN and TP in sewage outfalls of Shachang and Gangjian were higher than those in other sewage outfalls. The percentages of various N species in sewage outfalls showed that DIN was the major N species in sewage outfalls. There were higher level of TN and TP content in the Daliao River than those of tribtaries, and NO3--N and TPP were the major N and P species, respectively. In general, the nutrients analysis of tributaries, sewage outfalls and the Daliao River showed that nutrients of the Daliao River were affected by sewage outfalls. And the effect was significant and non-ignorable. |
