Impacts and hazards after the discharge of nuclear wastewater from Fukushima, Japan

  Recently, some news on the Internet about the discharge of Fukushima nuclear wastewater into the sea has aroused everyone’s attention. Today, the cooling tower manufacturer Trlon Air Conditioner will take you to understand the impact and harm caused by Fukushima nuclear wastewater and the contribution of closed cooling towers to water resources. .n0zCooling tower noise reduction treatment manufacturer

  Eight years ago, a leak occurred at the Fukushima nuclear power plant in Japan, the nuclear reactor was destroyed, and the 1 million tons of waste water produced had nowhere to go. The waste water contains radioactive elements, and Japan had to temporarily store the waste water in surrounding water storage tanks. Since these waste water needs to be continuously injected into cooling water, the water storage tank can no longer fit. Since the 1990s, various countries have formed an agreement not to dump nuclear waste water into the ocean. However, in order to digest the waste water, Japan proposed to dump it all into the Pacific Ocean in 2019, while claiming that the impact on the Pacific Ocean would be minimal. I am afraid that the Japanese will not believe these words, and of course experts from various countries will not be deceived. According to experts, if Japan dumps these waste water into the Pacific Ocean, neighboring countries such as China will be polluted first, and the waste water will soon flow to the United States and Australia. Under the influence of ocean currents, the entire Pacific Ocean will be fatally polluted, rendering the surrounding areas of the Pacific Ocean uninhabitable. On April 9, the Japanese government basically decided to discharge the Fukushima nuclear wastewater into the sea, which means that 10 years after the Fukushima incident, more than one million tons of nuclear wastewater will enter the global water cycle.n0zCooling tower noise reduction treatment manufacturer

  The current impact of Fukushima nuclear wastewater

  The first and most obvious thing is that the incidence of thyroid cancer in Fukushima local adolescents has increased by 118 times. Of course, the incidence of thyroid cancer itself is very low, the base number is small, and the sampling situation has a great influence on the final statistical results. Thyroid cancer is very easy to be affected. The absolute amount of the overall incidence caused by nuclear radiation is not particularly alarming, but such a number seems intuitive enough to make people feel scared. There is indeed a direct correlation between nuclear radiation and the incidence of cancer. This also leads ton0zCooling tower noise reduction treatment manufacturer

  The sales of agricultural products produced in Fukushima have plummeted, and the same products on the market may not be able to reach half the price of those produced in other regions.n0zCooling tower noise reduction treatment manufacturer

  The other is the proliferation of radioactive materials in the ocean. The picture above shows the spread of radioactive materials one year after the Fukushima Incident. It can be seen that pollutants have swept through a small part of the Pacific Ocean. As we all know, the half-life of radioactive materials is very long. For as long as tens of millions of years, radioactive substances in many organisms in the ocean have been detected to exceed the standard, and these substances will eventually reach the human body along the food chain. The specific impact is still unknown, but it must be long-term. And far-reaching.n0zCooling tower noise reduction treatment manufacturer

  my country will be affected after the discharge of Fukushima nuclear wastewater

  my country and Japan face each other across the sea, not far away, and they seem to be very susceptible to nuclear pollution. However, if emissions are true, at least our mainland will not be the first to bear the brunt. Let's take a look at the flow of nuclear waste water after it is discharged.n0zCooling tower noise reduction treatment manufacturer

  Fukushima is located at the intersection of the Japanese warm current and the Kuril cold current. The direction of the ocean current is from the southwest to the northeast, and then merges into the North Pacific warm current. At this time, it will reach the west coast of the United States and follow the California cold current. It will merge with the northern equatorial warm current and reach Southeast Asia. , It will flow north to reach the vicinity of the South China Sea. In addition, as can be seen from the figure below, there is an obvious step in the sea area of ​​southeastern my country, where the altitude rises sharply, and ocean currents cannot cross over a large area. Most of the seawater will return to eastern Japan with the Japanese warm current (for Taiwan Province The impact is relatively large).n0zCooling tower noise reduction treatment manufacturer

  Another point is that my country’s Pearl River, Yangtze River, Yellow River, etc. have large runoffs, forming offshore circulations, especially during the high water period in summer, which has a certain blocking effect on the external seawater. In winter, my country’s coastal waters The ocean current is from the Bohai Sea all the way to the south, which can also block part of the nuclear waste water from far away.n0zCooling tower noise reduction treatment manufacturer

  Therefore, theoretically speaking, with the North Pacific surrounding the nuclear waste water, only a small part of it can reach the coast of my country, and Taiwan will be relatively dangerous. However, some German research institutions pointed out that nuclear waste water will pollute half of the Pacific Ocean in 57 days. The pollution of these radioactive substances, even if it does not come to us with seawater, will appear with the food chain and global trade. Products that can be marketed may meet Standards, but long-term accumulation can also easily cause health risks. We must always pay attention to the latest situation and adjust our purchasing and diet plans in a timely manner.n0zCooling tower noise reduction treatment manufacturer

  In addition to the water cycle, pollutants will also be added to the atmospheric cycle. The impact of this part is currently unknown. To use a heavier analogy, the nest is covered, and there are no eggs. Mankind is a community with a shared future. We still hope that tomorrow's cabinet meeting in Japan will cancel this decision.n0zCooling tower noise reduction treatment manufacturer

  Nuclear sewage can pollute most of the Pacific Ocean in 57 days. It is difficult for our country to be alone. When nuclear waste water travels to the world along ocean currents, the world's fisheries will be affected. Although many people think that the ocean currents will have little impact on China’s waters, it is important to know that the Pacific Rim is the main fishing ground visited by my country’s ocean-going fishing vessels. In the past five or six years, my country’s total ocean-going fish catches have remained at about 2 million tons. Two of them are caught in the Pacific Rim. It can be seen that the safety of the entire Pacific Ocean is closely related to my country's fisheries.n0zCooling tower noise reduction treatment manufacturer

  The closed cooling tower operated by the cooling tower manufacturer Guangdong Trlon Air Conditioning also has its own contribution to saving water resources. The closed cooling tower (also called evaporative air cooler or closed cooling tower) is a tube heat exchanger placed in the tower. Inside, the cooling effect is ensured through the heat exchange of circulating air, spray water and circulating water. Because it is a closed cycle, it can ensure that the water quality is not polluted, well protect the efficient operation of the main equipment, and increase the service life. When the outside temperature is low, the sprinkler system can be stopped to save water. With the implementation of national energy conservation and emission reduction policies and the increasing scarcity of water resources, closed cooling towers have been widely used in industries such as steel metallurgy, power electronics, mechanical processing, and air conditioning systems in recent years.n0zCooling tower noise reduction treatment manufacturer

  Operation principle of closed cooling tower:

  1. Internal circulation: The circulating water enters the surface cooler after heat exchange and heating by the heat source, and sends the heat to the outside through the surface cooler, and then the cooled circulating water is sent to the heat source by the water pump.n0zCooling tower noise reduction treatment manufacturer

  2. External circulation: The spray water is sent from the water tank to the spray system. The spray water first exchanges heat with the filler to cool the spray water, and then contacts the surface cooler for heat exchange. Part of the hot steam is discharged through the fan, and the cooled The spray water will circulate again after it falls into the sink.n0zCooling tower noise reduction treatment manufacturer
