【摘要】：2013年3月至2014年1月对海口湾5条河流(五源河、鸭尾溪、海甸溪、横沟河、南渡江)和5个人工排水沟渠(观海台泄洪沟、秀英工业排污口、丘海大道泄洪沟、万绿园西沟、龙昆沟排污口)等10处主要陆源入海口的污染物种类、浓度及其时空分布特征进行分析。结果表明,海口湾主要陆源入海口水质均较差。五源河、秀英工业排污口、丘海大道泄洪沟、龙昆沟排污口、观海台泄洪沟和鸭尾溪的污染物浓度远超过《地表水环境质量标准》(GB 3838—2002)Ⅱ类标准,万绿园西沟、南渡江、海甸溪和横沟河的超标情况相对较轻。主要污染物为TN、TP、COD和氨氮。五源河和万绿园西沟的主要污染物浓度表现为枯水期丰水期,其余陆源入海口的主要污染物浓度随季节发生变化。
[Abstract]:From March 2013 to January 2014, five rivers in Haikou Bay (Wuyuan River, Ya Wei River, Haidian River, Henggou River, Nandu River) and 5 artificial drainage ditches (Guanhai platform flood discharge ditch, Xiuying industrial sewage outlet, Qiu Hai Road flood discharge ditch, Wan Luyuan Xi ditch), The species, concentration and spatial and temporal distribution of pollutants in the main land-based estuaries were analyzed. The results show that the water quality of the main land-based estuaries in Haikou Bay is poor. The pollutant concentrations of Wuyuan River, Xiuying Industrial sewage outlet, Qiu Hai Avenue Flood discharge ditch, Longkungou sewage outlet, Guanhai platform Flood discharge ditch and Ya Wei River are far higher than those of the Class 鈪，
