The statement that “hydropower is a renewable, environmentally friendly and non-polluting resource” is false.
On the surface, hydropower is a green, low-carbon way to produce energy, but building hydropower often changes a region's environment , it therefore has a negative impact on water. The environment and biological environment of a region, etc. will have certain impacts, and there is some probability that hydroelectric plants will cause earthquakes. Therefore, hydropower is not a completely environmentally friendly renewable resource and it also has some harmful effects.
Hydroelectric power generation is usually accompanied by long-term water storage, and retaining a large amount of water in the reservoir can change the river bed by downstream, affecting ainif certain living environments of local animals, and some even. will be a serious blow to the survival of certain animals.
Water storage in hydropower plants will not only affect the downstream river bed environment, but may also affect the area around the hydropower plant. Long-term water storage can and is likely to alter the local natural ecology. change the ecology of a region.
Operating principles of hydroelectric power plants
The operating principle is to fully ensure safety and satisfaction on the basis of economical and reasonable water resources and ensuring electricity. quality, development, economics and multiple supply requirements. Hydroelectric power plants perform tasks such as frequency regulation, peak regulation, phase regulation andbackup of the electrical system.
Generally, during floods, the water volume should be fully utilized to put all units into operation to achieve full power generation and multiple supplies, and support the load of basis of the electrical system when operating during tank water; During the supply period, the water load should be used as much as possible to support the base load and peak load of the power system, making full use of the adjustable output force to play the role of frequency regulation, peak regulation and emergency backup. system.
When a hydroelectric power station is in operation, it will be affected by the adjustment of compensation between different rivers; the impact of adjusting runoff when the same river is cascaded and the impact of power compensation between power plantsthermal; and hydroelectric plants in the electricity system. The operation of a hydroelectric power station includes normal operation, special operation, abnormal operation and economic operation. For the hydroelectric power station to operate normally, attention must be paid to the maintenance of the power station.
Can water used in power plants be used for bathing?
Cooling water is not harmful because it is mainly used to flow thanks to its fluidity and heat absorption. Heat from the equipment generally only comes into contact with the exterior surface of the equipment. Unlike dust removal water used in power plants, which is used to remove fly ash present in smoke, smoke contains harmful substances like sulfur, which are harmful to nature. Cooling water is not very harmful.
Itdepends on the type of water you use. There are many types of water in power plants. There are raw water, primary treated water, refined treated water, etc. If it is recycled water, it is not recommended for swimming. It can be used whether it is raw water or refined water. Regarding the steam used by power plants for electricity generation, it can in principle be used, but I personally think it should be distinguished according to the actual situation of the power plant. Some power plant boiler waters have been spiked with chemicals. Specific situation, specific analysis.
