【摘要】 对位于九龙江下游的龙海市东园排污口进行环境因子质量调查,结果表明:排污口的污水影响了该海域的环境质量,导致海水中的无机氮、磷酸盐分别超过四类、三类海水水质标准,局部海域已达到富营养化水平,有部分化学物质还存在不同程度的污染.又根据污染物排海总量控制的实际需求,探讨了龙海市东园排污口与邻近海域环境影响的因素,特别是当今普遍关注的海水水质恶化、赤潮频发、生态系统失衡等海洋生态环境问题.更多还原

【Abstract】 An investigation was conducted on the quality of environment factor of Dongyuan sewage outfall in Longhai City which is located at the lower reach of Jiulong River.The results showed that the environment quality of the sea area was affected by the sewage outfall and the contents of inorganic nitrogen and phosphate in sea water exceeded the fourth and third degree of the water quality standard,while some waters were cutrophicated.There was pollution at different degrees caused by some chemicals.According to the actual demand of controlling total mass of pollutants discharge,this paper studied the environment factors of Dongyuan sewage outfall in Longhai City and the adjacent sea area,especially the problems of marine ecological environment,such as water quality deterioration,red tide occurrence and ecosystem unbalance,which are generally concerned today.更多还原
