The impact of hydropower on water quality is multifaceted. The construction and operation of hydroelectric power plants will have both positive and negative impacts on water quality. Positive impacts include regulating river flow, improving water quality, and promoting the rational utilization of water resources; Negative impacts include eutrophication of reservoir water bodies and reduced self purification capacity of water bodies.
The positive impact of hydropower on water quality
Hydroelectric power has unique advantages in environmental protection. Compared to traditional fossil fuel power generation, hydroelectric power generation does not emit harmful gases and particulate matter, and has no pollution to the atmospheric environment. At the same time, the construction and operation of hydropower stations have a relatively small impact on water resources and will not cause damage to the aquatic ecosystem. In addition, hydropower can effectively regulate river flow, improve water quality, and promote the rational utilization of water resources.
The negative impact of hydropower on water quality
Although hydropower has advantages in environmental protection, its construction and operation can also have negative impacts on water quality. Building dams to intercept and store water can cause flowing water to become stagnant water, reducing the self purification capacity of the water body. Overgrowth of algae can lead to eutrophication of the reservoir water and a decrease in water quality. In addition, the construction of reservoirs may increase the probability of floods, block or alter stream basins, damage the original underwater ecological environment, reduce the survival rate of some underwater species, and lead to species extinction.
How to reduce the negative impact of hydropower on water quality
To reduce the negative impact of hydropower on water quality, some measures can be taken. For example, diverting a portion of the water source from the dam into a designated area to ensure ecological integrity, regulate the pollution behavior of factories along the river and the bad habits of residents. In addition, scientifically reasonable planning and construction measures are also key to reducing negative impacts.
