摘要
在晋江入海口(鲟浦)断面设置3个水质监测点位,通过手工采样监测法,考察丰水期和枯水期晋江入海口溶解氧、pH值、COD、氨氮、总磷、高锰酸盐等指标的变化情况,充分了解晋江入海口的水环境状况。调查结果表明:入海口水质的主要超标因子是氨氮和总磷,其中氨氮超标最为严重,溶解氧也出现过超标的情况;枯水期的溶解氧浓度、总磷浓度明显高于丰水期,氨氮浓度则表现为丰水期大于枯水期的特点。
Three water quality monitoring points were set up at the section of the Jinjiang estuary(Xunpu).Through manual sampling monitoring method,changes in dissolved oxygen、pH value、COD、ammonia nitrogen、total phosphorus、permanganate and other indicators at the Jinjiang estuary during high and low water periods were investigated to fully understand the water environment conditions at the estuary.The survey results show that the main exceeding factors of water quality at the sea inlet are ammonia nitrogen and total phosphorus,with ammonia nitrogen exceeding the standard the most severely,and dissolved oxygen also exceeding the standard;the concentration of dissolved oxygen and total phosphorus in the dry season is significantly higher than that in the wet season,while the concentration of ammonia nitrogen shows a characteristic of being higher in the wet season than in the dry season.
