地表水中温度、溶解氧、氨氮的关系研究

随着人们环境保护意识增强,地表水健康程度受到重视,人类聚集性污染对地表水的影响很大,因此选取了城区中心环城河支河入河口处点位,对地表水中温度、溶解氧、氨氮三个主要指标在时间维度上的对应关系展开研究。由此得出:溶解氧和氨氮在不同水温条件下变化趋势一致,在相近温度条件下溶解氧浓度和氨氮浓度变化趋势成反比,我们可以通过曝气让河道水质溶解氧浓度升高,相应氨氮浓度会降低,水质质量就会得到保证,为治理河道污染提供有力依据和方法;治理技术需要发展,以后通过水生态技术让河道更美丽。

With the enhancement of people’s awareness of environmental protection,attention has been paid to the health of surface water,and human aggregation pollution has a great impact on surface water,so the point at the estuary of the branch river around the city center is selected.The corresponding relationship of temperature,dissolved oxygen and ammonia nitrogen in surface water in time dimension was studied.As a result,it is concluded that the change trend of dissolved oxygen and ammonia nitrogen is the same under different water temperature,and the change trend of dissolved oxygen concentration and ammonia nitrogen concentration is inversely proportional to the similar temperature condition,so we can increase the dissolved oxygen concentration of river water through aeration,so that the corresponding ammonia nitrogen concentration will decrease,and the water quality will be guaranteed,thus providing a strong basis of methodology for the treatment of river pollution.The treatment technology needs to beenhanced,and the water ecological technology will be used to make the river more beautiful in the future.
