南沙区蕉门水道水质总磷问题的探究

Study on the problem of total phosphorus in Jiaomen Waterway of Nansha District

从2017年10月起,国家上收监测权,国控断面实施采测分离规定,今年1-8月南沙区(以下简称"我区")蕉门水道蕉门断面水质总磷浓度达到0.17 mg/L,同比上升142.8%,水质从Ⅱ类下降到Ⅲ类。本文对沙区蕉门水道水质总磷问题进行了深入研究,找出了蕉门断面总磷超标的问题根源,确定了重点污染源,以便为改善水环境质量以及管理部门提供相应的数据支撑。

From October 2017,the state has received monitoring rights and the national control section has implemented the separation of production and testing regulations.From January to August this year,the total phosphorus concentration of the water in the Jiaomen section of the Jiaomen waterway in Nansha District (hereinafter referred to as “I District”) reached 0.17 mg/L,up 142.8% year-on-year,and water quality dropped from Class II to Class III.In order to improve the quality of the water environment,find out the root cause of the problem of excessive phosphorus in the banana gate section,identify key pollution sources,and provide corresponding data support for the management department.
