摘要
根据小东江2017年至2021年的监测数据平均值,对小东江石碧、山阁、镇盛3个重点断面的监测数据进行分析和水质变化趋势探究。结果表明茂名市小东江水体中的氮磷是最主要的污染物,下游石碧断面在三个断面中水质污染最为严重,波动最大。城区及沿线镇、村生活污水是造成水体污染最主要的原因。建议政府要加强城镇和农村污水治理,强化对养殖废水的防治,同时监督工业废水的排放,从源头上解决污水的问题。
Based on the means of data monitored in Xiaodong River from 2017 to 2021,the data from three key sites of Xiaodong River,namely Shibi,Shange and Zhensheng,were analyzed and the variation tendency of water quality was also explored.The results showed that nitrogen and phosphorus are the main pollutants in Xiaodong River,and Shibi section is the most polluted and fluctuated among the three sections.Domestic sewage is the main cause of water pollution in urban areas,towns and villages along the drainage system.It is recommended that the government can strengthen sewage treatment in urban and rural areas,strengthen the prevention and treatment of aquaculture wastewater,and supervise the discharge of industrial wastewater,so as to solve the problem of sewage from the source.
