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

Industrial and agricultural development of coastal and marine development projects have caused pollution to the sea.The sewage from land is an important reason of pollution in coastal water.In order to protect marine environment and realize sustainable development at the same time of achieving rapid development of marine industry,we investigate water quality of sea outfall along coastline in HaiKou city. We use fixed-point sampling method to collect water samples for laboratory analysis according to the diameter 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.
