Abstract:

In recent years, the water pollution problem has increasingly attached the attention of people. Application of ecological environment engineering inspecting and repairing the water quality was widely used. Periphyton was widespread in the water environment and extremely sensitive to the change of water quality, so it could be used more comprehensively to monitor water quality change and detect both physicochemical property of the water and the change of periphyton community. This monitoring method has been widely used in our country. Meanwhile, because periphyton was able to bear or endure corrupt sex or sensitivity differently, and was also particularly sensitive to some special chemical composition change, it could exert the indicative functions. In addition, periphyton has good adsorption and effectively removed water pollutants such as the nitrogen, phosphorus and some heavy metal ions, suggesting that periphyton also has a high potential in water purification. This paper reviewed the role of periphyton in water quality monitoring.
