Chapter 538 Binary structure graphene film

The scientific researcher applied with a bit of excitement, and explained to Wu Siyuan, "Wu Dong, this graphene film with a binary structure is really amazing."

"As you can see, the transparent liquid passing through this [two-dimensional structure graphene film] is 100% water molecules, which is the so-called pure water, which is more [pure] than the C'estbon pure water circulating in 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 the water body, the water molecules pass through at a faster rate."

Wu Siyuan nodded, he had already known this result, so he was not surprised at all.

But Huang Yuping, the president of the group who accompanied him, was very excited. He said to Wu Siyuan, "Wu Dong, this graphene film technology treats sewage, [Dianjinsang] treats the metal components of sludge, and super-decomposing bacteria treats petroleum derivatives. In this way Firstly, our group's environmental protection treatment process will reach a new level, not only with higher efficiency, but also with lower cost. We can deal with all kinds of garbage in three dimensions! Garbage, for our group, is the real treasures!"

"Oil can be squeezed out of the stone!"

"Our group's environmental protection business can also be promoted to the whole country and to the international market. Due to cost or other reasons, the domestic markets that were not settled in the past can also be fully implemented."

Huang Yuping continued, "Similarly, this graphene film technology can also be used in seawater desalination."

"my country is actually a country with severe drought and water shortage. The total fresh water resources are 28000 trillion cubic meters, accounting for 6% of global water resources, ranking fourth in the world after Brazil, Russia and the Maple Leaf Country, but the per capita is only 2200. cubic meters, only one-fourth of the world average and one-fifth of the beautiful country, ranking very low in the world, ranking 121st, and being one of the 13 countries with the poorest per capita water resources in the world."

"After deducting the difficult-to-use flood streams and groundwater resources scattered in remote areas, the actual amount of fresh water resources available in my country is even less, only about 11000 trillion cubic meters, and the per capita usable water resources are about 900 cubic meters. , and its distribution is extremely uneven.”

"By the end of the 20th century, more than 600 of the more than 400 cities across the country had insufficient water supply, of which 110 were severely water-scarce, and the total water shortage in cities across the country had reached 60 billion cubic meters. "

"Especially in the Loess Plateau, there is a serious water shortage. In the North China Plain, groundwater has been pumped out extensively, and there has been obvious ground deposition."

"Although our group 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, introduced our group's garbage and sewage treatment technology, and maximized the recycling of various waste water, but it is a drop in the bucket. , This is treating the symptoms rather than the root cause, and water shortage will restrict the further development of the Loess Plateau and other water-scarce regions across the country."

"In addition, according to monitoring, groundwater in most cities in my country is currently subject to a certain degree of point and surface pollution, and there is a trend of increasing year by year. The increasingly serious water pollution not only reduces the use of water bodies, but also further exacerbates the contradiction of water shortages. , has had a serious impact on the sustainable development strategy being implemented in our country, and also seriously threatens the drinking water safety of urban residents and the health of the people."

"The technology newly developed by our group can not only effectively deal with pollution in water bodies, but also produce a large amount of pure water through seawater desalination, which can not only effectively supplement groundwater, but also meet my country's water resource needs."

"The south of our country is relatively rich in water resources, while the north is short of 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 problem of water shortage in northern China, especially in the Huang-Huai-Hai Basin. The planned population is 4.38 million."

"In the past, people in many places needed to live by drinking high-fluorine water and brackish water. For example, the hardness of tap water in the capital was two-thirds higher than it is now. But it is different now. The center line of the [South-to-North Water Diversion] With the East Route Project, the accumulated water diversion has exceeded [-] billion cubic meters, and more than [-] cities in the north have used [South Water], and the water from the South-to-North Water Diversion has become their main source of water."

"However, the cost of water transferred from the south for thousands of miles is not low."

“在2014年的时候，南水北调中线水源工程综合水价为每立方米0.13元(含税)，干线工程禹省南阳段、禹南省黄河南段(除南阳外)、禹省黄河北段、翼省、津门市、首都市各口门综合水价分别为每立方米0.18元、0.34元、0.58元、0.97元、2.16元、2.33元。需要注意的是，该水价并非居民用水价格，只是根据调水成本测算出来的【成本价】。”

"It doesn't seem that high. Compared with the cost of seawater desalination technology, the best seawater desalination technology now costs at least 3 yuan per cubic meter of water. This is because the fossil fuels in some countries are cheap. cost price."

"However, this remote water diversion project currently does not take into account the project investment and the indirect economic losses of the diverted area. If the project investment, operation, purification treatment, management costs and losses such as evaporation, leakage, interception, and pollution are included Including land occupation and other factors, the cost of water diversion projects will rise in a straight line. In some places, the cost of a 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 per ton. .”

Huang Yuping talked endlessly, he seemed to have a well-thought-out plan, and all kinds of data came out of his mouth.

"Wu Dong, in the past, the country chose the South-to-North Water Diversion Project because the technology was not mature. But now, our group has the most outstanding seawater desalination technology in the world. As long as the electricity price is stable, our seawater desalination cost will be 0.5 yuan/ton about."

"This cost makes us unrivaled in the market. Our water supply cost is much lower than the water transfer cost. Moreover, we don't need to consider the impact of the water transfer project on the economy and environment of the water transfer area, because we The raw materials come from the vast and boundless sea.”

"We can build seawater desalination plants one after another along the long coastline of our country, and transport the desalinated seawater to the nearby land in the north where water is scarce."
