摘要:
以2013年1月和6月实测数据为参考,分析赣江水体氨态氮( NH4+-N)、硝态氮( NO3--N)和总磷( TP)分布特征和污染来源。结果表明:赣江水体枯水期的NH4+-N和NO3--N平均质量浓度高于丰水期,但不具有统计学意义;枯水期的TP平均质量浓度显著高于丰水期。 NH4+-N在赣州和南昌市区下游出现极大值;枯水期干流NO3--N质量浓度在赣州和南昌市区下游较高,丰水期干流浓度相差不大,支流中桃江和袁水NO3--N质量浓度明显偏高;枯水期赣江TP质量浓度在赣州市和南昌市下游出现高值区,丰水期只在赣州市下游出现高值区。通过赣江氮磷营养盐的时空分布特征以及与Cl-质量浓度的相关性得出,赣江NH4+-N污染主要来源于城市污水排放;NO3--N在枯水期主要来源于城市污水排放,丰水期则来自农业污水和城市污水的共同作用;TP主要来源于城市污水排放,其次为农业污水影响。
Abstract:
Based on the measured concentration of ammoniacal nitrogen( NH4+-N ),nitrate nitrogen( NO3--N )and total phosphorus(TP)in Ganjiang River in January and June 2013,the distribution characters and pollution sources of NH4+-N,NO3--N,TP and their influencing factors are analyzed. The results show that the mean concentration of NH4+-N and NO3--N were higher in the dry season than that in the wet season without statistical significance,while the mean concentration of TP was significantly higher in the dry season than that in the wet season. The concentra-tion of NH4+-N had higher value in the downstream of Ganzhou City and Nanchang City. The concentration of NO3--N in mainstream had higher value in the downstream of Ganzhou City and Nanchang City in the dry season,but in the wet season,the difference of NO3--N concentration in mainstream was small. As for the tributary,Taojiang River and Yuan River had higher concentration of NO3--N. The concentration of TP had a series of high value in the downstream of Ganzhou City and Nanchang City in the dry season,while in the wet season,this only appeared in the downstream of Ganzhou City. By studying the temporal and spatial distributions of nitrogen and phosphorus nutri-ents,together with the correlation test between NH4+-N,NO3--N,TP and Cl-,it was found out that the main pollu-tion source of NH4+-N was urban sewage,and the main pollution source of NO3--N was urban sewage in the dry sea-son,however,both urban sewage and agricultural drainage played an important role in the wet season. As for the pol-lution source of TP,urban sewage came first,followed by agricultural drainage.
