水生植物水质净化作用的研究进展

The Research Progress of Waste Water Treatment by Aquatic Plants

随着城市的发展,污染物排放量不断增加,水生态系统受到不同程度污染。为了解决水污染问题,人们通常采用营养盐控制法、直接除藻法、生物调控法和生态调控法4种方法。各种方法各有优缺点,且均能达到处理污水的效果,其中水生植物处理城市污水法是生态调控法中应用效果最好的。该方法运用水生植物的自我净化功能来达到净化水质的目的,不仅可以实现污水的良性循环,还能提升污水的经济价值。

Pollutant emissions continue to increase with the development of urbanization, and water ecological system were more seriously polluted. To tackle the problem, different methods were used, for instance, nutrient control method, direct remove algae method, biological control method, ecological control method. These methods all can achieve the objective of getting waste water treated though they have their respective advantages and disadvantages. Among them, the method using aquatic plants is the best method. Exploiting the self purification function of aquatic plants, not only can this method realize the virtuous recycling of waste water but lift the economic value of the treated water.
