What can we do to protect water resources? Tell me.

How to protect water resources? In the final analysis, human protection of the environment is based on the protection of the increasingly depleted resources on the earth, and the protection of water resources, the most basic condition for human survival and development, bears the brunt. Below, the author talks about some superficial understanding on how to protect water resources in modern production and life. First of all, we should establish the consciousness of cherishing water and carry out water resources warning education. For a long time, most people generally think that water is an inexhaustible "cornucopia", which is wasted in use. I wonder if I consciously cherish it. In fact, the water resources on the earth are not inexhaustible. Especially in China, the per capita water resources are not rich, the regional distribution is uneven, and the year is unpredictable, with great inter-annual differences. Coupled with serious pollution, water resources are even more scarce, which is vividly reflected in the repeated water cuts of the Yellow River. National water resources utilization projects such as "Yellow River Diversion Project" and "South-to-North Water Transfer Project" are aimed at solving the water shortage problem in some areas, but we should think deeply: Where can we "divert water from the Yellow River" when the water in the Yellow River is exhausted? The water in the south is polluted. How to "transfer water to the north"? Therefore, people must establish the consciousness of water crisis, take saving water resources as our conscious code of conduct, and carry out water resources warning education in various forms. Secondly, we must develop water resources rationally to avoid the destruction of water resources. Water resources development includes surface water resources development and groundwater resources development. Water resources are used by the state. Therefore, the development of production and domestic water must comply with the relevant provisions of the Water Law of People's Republic of China (PRC) and make overall plans. When exploiting groundwater, because the water quality of each aquifer is quite different, it should be exploited by layers; Contaminated diving and confined water shall not be mixed; For exploration projects that expose and penetrate the water layer, layered water sealing and hole sealing must be carried out in strict accordance with relevant regulations to effectively prevent water pollution and ensure the sustainable development of water bodies. Modern water conservancy projects, such as flood control, power generation, shipping, irrigation, aquaculture water supply, etc. , while exerting one or more economic benefits, it will have a certain negative impact on the natural environment and social environment of the project location, upstream and downstream, estuary and even the whole basin, and may also cause water resources destruction in a certain range. Therefore, since 1970s, many countries have carried out environmental assessment on water conservancy projects. In China, environmental assessment is needed in the feasibility study stage of water conservancy projects. Large and medium-sized projects should prepare environmental impact reports, and small and medium-sized projects with little impact on the environment should prepare environmental impact assessment tables. In addition, the destruction of water resources by some mining industries can not be ignored. For example, coal mining discharges 0.88 cubic meters of water for every ton of coal mined. According to the annual coal mining of 300 million tons in our province, the loss of groundwater resources is as high as 250 million cubic meters, which has caused great damage to the geological structure of groundwater. For another example, unrestricted deforestation will cause serious damage to vegetation, and it will also have a certain impact on soil and water conservation and surface burial of water resources. Third, improve the utilization rate of water resources and reduce water waste. The key to effective water saving is to reuse water resources by using "reclaimed water". If reclaimed water can be used in the whole society, it will not only bring considerable economic and environmental benefits, but also form a good atmosphere for cherishing water resources in society. At present, many large and medium-sized enterprises have developed and utilized reclaimed water. For example, all mines in Huozhou Coal and Electricity Group use reclaimed water to sprinkle water underground and flush toilets on the ground, which has achieved good economic and social benefits. In addition, the effective utilization of water resources is regulated by economic leverage. Because water control is not in place, many places have flowing water, and some places will "hold bowls and pray". Therefore, it is necessary to install an effective water metering device and implement the principle of using more water and charging more, so as to achieve the purpose of saving water. Urban water quota management is an internationally accepted method. On the premise of scientific verification of water consumption, adhere to the principle of classified treatment. Different water prices shall be imposed on citizens' domestic water, industrial and commercial enterprises' water and government institutions' water, and the excess shall be appropriately raised to cultivate citizens' habit of saving water. While saving water resources, we should avoid ineffective waste. In winter in the north, water pipes are prone to frost crack and serious water leakage, so special attention should be paid to prevention and inspection; With the development of social economy and the acceleration of urbanization, in order to alleviate the shortage of water resources, in addition to vigorously saving and protecting water resources, inter-basin water transfer has become an inevitable choice for cities in northern China, which will inevitably bring about changes in the relationship between supply and demand of water resources, so water rights trading must be implemented; Since China implemented the "welfare water" system, water has not been treated as an economic commodity. Therefore, in the preparation of water resources, the market mechanism is usually replaced by the control method. At present, we should change our ideas, recognize the natural and commodity attributes of water resources, follow the laws of nature and value, truly treat water as a commodity, rationally allocate water resources by using market mechanisms, and reduce resource waste. Fourth, carry out water pollution prevention and control to realize comprehensive utilization of water resources. Water pollution includes surface water pollution and groundwater pollution. Industrial wastewater, industrial garbage, industrial waste gas, domestic sewage and domestic garbage produced in the production process can all cause water pollution through different infiltration methods. For a long time, environmental incidents caused by direct discharge of industrial production sewage are common, which have brought extremely bad effects on human production and life. Therefore, effective prevention and control of production and domestic sewage should be carried out. Cities can adopt centralized sewage treatment; Industrial enterprises must implement the "three simultaneities" system of environmental protection; According to the different properties of production sewage, corresponding sewage treatment measures are taken. In short, we must resolutely implement the supervision and management system of water pollution prevention and control, adhere to the principle that whoever pollutes will control it, strictly implement the one-vote veto system for environmental protection, promote the sewage treatment work of enterprises, and finally realize the comprehensive utilization of water resources. Water is the material basis for the existence of life on earth, and water resources are the primary condition for maintaining the sustainable development of the earth's ecological environment. Therefore, protecting water resources is the greatest and most sacred duty of mankind.
