【摘要】 淡水藻类作为水体中的初级生产者,分布广泛,适应性强,在水生生态系统食物链中占据着十分重要的地位,在水质监测中起着关键的作用。通过对藻类生长与水环境之间的相互关系进行简要的概述,探讨了pH值和氮磷对淡水藻类的生长的影响,以及淡水藻类的生长对外界环境的影响。藻类不但应用于水质监测,而且还能去除水体中的氮、磷等营养物质和其它有机物,对自然水域中的污水有良好的净化作用。重点论述淡水藻类在水质监测和污水净化中的作用以及利用淡水藻类来处理污水的方法。并提出了保护水资源的相关建议,为综合监测和治理水环境提供一定的理论依据和支持。更多还原

【Abstract】 As a primary producer in water,freshwater algi are widely distributed and adaptable.They have a very important position in food chain of aquatic ecosystems and water quality monitoring.A brief overview about the relationship between algae growth and water environment was given in this paper.The impacts of the pH,C/N on the growth of freshwater algae and the growth of freshwater algae on the outside environment were discussed.Freshwater algi are applied not only to monitor water quality,but also to remove water of nitrogen,phosphorus and other nutrients and organic matter in wastewater with a good effect for sewage purification.Focuses on the role of the freshwater algae in the water quality monitoring and sewage purification emphasized.The methods of using freshwater algae to treat sewage were introduced.Some recommendations to protect water resources were put forward.更多还原
