A waste of water resources data

However, in our daily life, water is wasted everywhere. In the Yellow River basin, which is seriously short of water, traditional flood irrigation is widely used in agricultural irrigation.

The average water consumption per mu in the upstream Ningmeng irrigation area is more than 1 cubic meters, which is several times to ten times higher than that in the water-saving irrigation area. Even the Yellow River Diversion Irrigation Areas in Henan and Shandong provinces, which are suffering from cut-off, are flooded when there is water, and sighing when there is no water. At present, the utilization rate of agricultural water in China is generally .3 to .4, and the water consumption per unit of production is 2 to 2.5 times that of developed countries.

there is also a serious waste of industrial water. According to statistics, at present, the reuse rate of industrial water in China is only about .3, which is far lower than .75 in developed countries. The water consumption per unit GDP is 15 to 1 times that of developed countries, and the water consumption per unit of some important products is several times or even dozens of times higher than the advanced level abroad.

not only that, but also the water environment in China has been deteriorating in recent years. The discharge of wastewater and sewage in China is increasing at a rate of 1.8 billion tons per year, and the daily discharge of industrial wastewater and domestic sewage is nearly 164 million tons.

Extended information:

In recent years, the water conservancy department has tested the water quality of nearly 1, kilometers of about 7 large and medium-sized rivers in China. As a result, nearly 1/2 of the rivers have been polluted and 1/1 of them have been seriously polluted, and the river has lost its use value.

The seven major rivers in China from south to north have been polluted to varying degrees. At present, more than 9% of urban waters in China are seriously polluted. There are 7 million people drinking water with excessive Escherichia coli content, 17 million people drinking water polluted by organic matter, and 3 million urban residents are facing the worldwide problem of water pollution.
