The scientific researcher applied with a bit of excitement and explained to Wu Siyuan, "Dr. Wu, this binary structure graphene film is really amazing."
"As you can see, the transparent liquid passing through this [binary structure graphene film] is 100% water molecules, which is the so-called pure water. It is more [purer] than the Cippo purified water circulating on the market. !”
"Other objects that are not water molecules will be completely trapped here."
"With this technology, our sewage treatment efficiency will be significantly improved."
"And, through experiments, we also found that if more pressure is applied to a body of water, water molecules move through it at a faster rate."
Wu Siyuan nodded. He had already known about this result, so he was not surprised at all.
Huang Yuping, the group president who accompanied him, was very excited. He said to Wu Siyuan, "Dr. Wu, this graphene film technology treats sewage, [Dianjin Mulberry] treats the metal components of sludge, and super decomposing bacteria treat petroleum derivatives. This way As a result, our group's environmental protection treatment process will reach a new level. Not only will the efficiency be higher, but the cost will also be lower. We can process all kinds of garbage three-dimensionally! Garbage, for our group, is a real A treasure!"
"Oil can be squeezed out of the stones!"
"Our group's environmental protection business can also be promoted nationwide and internationally. Domestic markets that have not been established in the past due to cost or other reasons can also be fully implemented."
Huang Yuping continued, "Similarly, this graphene film technology can also be used in seawater dewatering."
“Our country is actually a country suffering from severe drought and water shortage. The total amount of water resources is 2.8 trillion cubic meters, accounting for 6% of global water resources. It ranks fourth in the world after Brazil, Russia and Maple Leaf Country, but the per capita water resources are only 2,200 cubic meters, which is only one-quarter of the world average and one-fifth of the United States. It ranks very low in the world, ranking 121st. It is one of the 13 countries with the poorest per capita water resources in the world. "
“After deducting the difficult-to-use flood runoff and groundwater resources scattered in remote areas, the amount of usable water resources in my country is even less, only about 1.1 trillion cubic meters, and the per capita available water resources is about 900 cubic meters. meters, and its distribution is extremely uneven.”
"At the end of the 20th century, more than 400 of the country's more than 600 cities had water shortage problems, of which 110 were severely water-short, and the total urban water shortage across the country had reached 6 billion cubic meters. "
"Especially in the Loess Plateau, there is a serious water shortage. In the North China Plain, groundwater has been extracted intensively, and there has been obvious ground sedimentation."
“Although our group has invested a lot of money in the Loess Plateau before, and signed environmental protection treatment contracts with various provinces and cities on the Loess Plateau, and introduced our group’s garbage and sewage treatment processes to maximize the recycling of various wastewaters, it is still a drop in the bucket. , this is treating the symptoms but not the root cause, and water shortage will restrict the further development of water-scarce areas across the country such as the Loess Plateau."
"In addition, according to monitoring, groundwater in most cities in my country is currently subject to a certain degree of point and area pollution, and the trend is getting worse year by year. The increasingly serious water pollution not only reduces the use function of water bodies, but also further aggravates the contradiction of water shortage. , It has had a serious impact on the sustainable development strategy being implemented in our country, and it also seriously threatens the drinking water safety of urban residents and the health of the people."
"This newly developed technology by our group can not only effectively deal with pollution in water bodies, but also produce a large amount of pure water through seawater decontamination, which can not only effectively replenish groundwater, but also meet my country's water resources needs."
"The south of my country is relatively rich in water resources, while the north is lacking in water resources, so the country has implemented the strategic project of [South-to-North Water Diversion]."
“The South-to-North Water Diversion Project mainly solves the problems in northern my country.
Especially the water shortage problem in the Huang-Huai-Hai basin, the planned area has a population of 438 million people. "
"In the past, people in many places had to rely on drinking water with high fluoride and brackish water. The hardness of tap water in the capital was two-thirds higher than it is now. But it is different now. The middle line of the [South-to-North Water Diversion Project] and the Eastern Line Project, the cumulative water diversion volume has exceeded 40 billion cubic meters, and more than 40 cities in the north have used [South Water], and the water from the South-to-North Water Diversion has become their main water source."
"However, the cost of transferring water all the way from the south is not low."
“In 2014, the comprehensive water price of the middle route water source project of the South-to-North Water Diversion Project was 0.13 yuan per cubic meter (tax included). The main line project included the Nanyang section of Yu Province, the southern section of the Yellow River in Yunan Province (except Nanyang), the northern section of the Yellow River in Yu Province, and The comprehensive water prices at the gates of the province, Jinmen City, and Capital City are 0.18 yuan, 0.34 yuan, 0.58 yuan, 0.97 yuan, 2.16 yuan, and 2.33 yuan per cubic meter respectively. uu read books
It should be noted that the water price is not the price of residential water, but the [cost price] calculated based on the cost of water transfer. "
"It doesn't seem high. Compared with the cost of seawater dehydration technology, the best seawater dehydration technology now costs at least 3 yuan per cubic meter of water. This is because fossil fuels in some countries are cheap. Low cost price.”
"However, this remote water diversion project currently does not include project investment and indirect economic losses in the areas where water is diverted. If the costs of project investment, operation, purification treatment, management, etc. and losses such as evaporation, leakage, interception, and pollution are included, Taking into account land occupation and other factors, the cost of water diversion projects will rise sharply. In some places, the cost of one ton of [South Water] may be as high as 10 yuan, and the cost of water diversion in some remote areas may even reach 18 yuan/ton. .”
Huang Yuping talked non-stop. He seemed to be confident, and all kinds of data came out of his mouth.
"Dr. Wu, in the past, the technology was immature, so the country chose the South-to-North Water Diversion Project. But now, our group has what can be said to be the world's most outstanding seawater dewatering technology. As long as the electricity price is stable, our seawater dewatering cost is 0.5 yuan. /ton or so.”
"This cost gives us unrivaled competitiveness in the market. Our water supply cost is much lower than the cost of water transfer. Moreover, we do not need to consider the impact of water transfer projects on the economy and environment of the water transfer area, because we The raw materials come from the vast and boundless sea.”
"We can definitely build seawater dewatering plants one after another along our country's long coastline, and continuously transport the decontaminated seawater to the water-scarce northern land."
