基于生物膜技术的城市污水脱氮技术
|
摘要
城市发展过程中会产生很多污水,污水的来源比较广泛,主要包括居民的生活污水以及工业废水,还有就是部分降水。城市污水中含有大量的氮、磷等污染物,这些氮、磷污染物如果不得到有效的处理或者是处理效果没有达到预期就容易导致水体富营养化,水质发生变化进而导致水体生态环境遭到了破坏,加剧了水资源短缺、水污染等情况。所以,必须加强城市污水处理工作,通过采取有效措施对城市污水进行净化。主要针对城市污水脱氮技术展开论述,以生物膜技术为基础进行详细探讨。
There will be a lot of sewage in the process of urban development.The sources of sewage are mainly including the domestic sewage and industrial wastewater of residents,and some precipitation.Urban sewage contains a large amount of pollutants such as nitrogen and phosphorus.If these nitrogen and phosphorus pollutants are not effectively treated or the treatment effect is not as expected,it will easily lead to eutrophication of water bodies,and the water quality will change and the ecological environment of the water body will be affected.Destruction has aggravated water shortages and water pollution.Therefore,it is necessary to strengthen urban sewage treatment work and take effective measures to purify urban sewage.The article discusses the denitrification technology of urban sewage and discusses it in detail based on biofilm technology.
