海口市海岸线入海排放口污染源调查与分析

Pollution source survey and analysis of Sea outfall Along Coastline in HaiKou City

沿海工农业的发展和海洋开发事业的兴起,给海洋造成了污染。而陆域排污是海洋近海污染的重要原因。为了在实现海洋产业经济可持续发展,对海口市海岸线入海口水质进行调查。本实验采用定点采样的方法,根据排污口的口径大小、年排污水的总量、以及对周边海域的污染程度采集水样。结果表明,海岸线入海口排污废水中的COD、总氮、磷酸盐、氨氮等严重超标。表明近海水域富营养化加剧,由此引发的各种海洋灾害发生的可能性加大。

Industrial and agricultural development of coastal and marine development projects have caused pol-lution to the sea. The sewage from land is an important mason of pollution in coastal water. In order to protect marine environment and realize sustainable development at the same time of achieving rapid development of ma-rine industry, we investigate water quality of sea ouffall along coastline in HaiKou city.We use fixed -point sampling method to collect water samples for laboratory analysis according to the di-ameter size of the outfall, the annual amount of sewage water and pollution degree of surrounding water. The result shows that several conventional monitoring indexes such as COD, total nitrogen, phosphate and ammonia exceed standard seriously in wastewater from sea outfall along coastline. Which will increase the possibility of various marine disasters.
