1. Nuclear wastewater generally refers to the wastewater discharged from nuclear power plants. According to TEPCO, 63 types of radioactive materials are found in the nuclear wastewater.
On April 13, Japan officially decided to discharge nuclear wastewater from the Fukushima Daiichi Nuclear Power Plant into the ocean, which is harmful to the marine environment.
On April 13, Japan** officially decided to discharge millions of tons of nuclear-contaminated water from the Fukushima Daiichi Nuclear Power Plant into the sea, and many countries questioned and opposed this. With regard to this important matter, which has a bearing on the vital interests of its own people and the people of neighboring countries, and the international public health and security, it is extremely irresponsible for the Japanese side to insist on going its own way without full consultation with its neighboring countries and the international community.
On April 15, Wu Jianghao, assistant minister of China, summoned the Japanese ambassador to China, Hideo Taru, to make solemn representations on Japan's decision to dispose of the wastewater from the Fukushima nuclear power plant accident by marine discharge.
On April 15, the Korean Central News Agency (KCNA) published a commentary saying that on the 13th, Japan, despite the strong opposition of the international community, decided to discharge a large amount of nuclear sewage from the Fukushima nuclear power plant accident into the sea. This is a serious threat to human health and safety and the ecological environment.

The methods for treating nuclear wastewater are as follows:
1. If the amount is not large, as long as the emission is controlled, tritium and water can be directly evaporated.
2. Landfill the remaining solid waste, but tritium may pollute the air.
3. Suck out the solid waste first through adsorption, and after sucking it out, the solid waste is still taken to landfill, and then the remaining wastewater is directly discharged into the sea, or stored in a tank for a while.
4. The purpose of the wastewater treatment is to separate the pollutants in the wastewater in a certain way, or decompose them into harmless and stable substances, so as to purify the sewage.
5. Generally, it is necessary to prevent the infection of poisons and germs, and avoid visible objects with peculiar smell and bad feelings, so as to meet the requirements of different uses.
6. Wastewater treatment is quite complex, and the selection of treatment methods must be considered according to the quality and quantity of wastewater, and the use of the receiving water body or water discharged to it.
Application of tritium: 1. Tritium and its labeled compounds play an important role in military, industrial, hydrological, geology, concealment and various scientific research fields. In many research efforts in the life sciences, tritium-labeled compounds are an indispensable research tool.
2. For example, the mechanism of action and analysis of enzymes, cytology, molecular biology, receptor binding research, radioimmunoassay, pharmacokinetics, and cancer diagnosis and **, etc., are inseparable from tritium-labeled compounds. When using tritium-labeled compounds for tracer experiments, it is important to pay attention to the isotopic effects of hydrogen, self-radiation, and the stability of tritium-labeled compounds under experimental conditions in order to obtain correct experimental results. <>

Summary. Hello, after inquiry, the difference between nuclear wastewater and nuclear sewage is: nuclear wastewater mainly comes from the cooling water circulation system of the nuclear reactor itself. 2.Nuclear wastewater** is used in other maintenance and treatment systems of nuclear power plants, such as filtration systems, cleaning systems, etc.
Hello, after querying the key Kailu, the difference between nuclear wastewater and nuclear sewage is: nuclear wastewater mainly comes from the cooling water circulation system of the nuclear reactor itself. 2.Nuclear wastewater** is used in other maintenance and treatment systems of nuclear power plants, such as filter tape systems, cleaning systems, etc.
Hazards of nuclear wastewater hail:1Nuclear wastewater contains a large number of harmful substances such as radioactive materials, heavy metals and organic compounds, which can cause damage to the raw arubber system, affect biodiversity, and may lead to the extinction of some species.
2.Harmful substances in nuclear wastewater may contaminate surface water and groundwater, resulting in a decline in water quality and affecting the safety of drinking water.

Let's first understand what is nuclear wastewater: nuclear sewage is mainly sewage with harmful substances generated during the use of nuclear power plants. Among them, there are more than 60 kinds of radioactive elements, these radioactive substances are usually the highest content of tritium, which can be ingested by the human body by the food chain, respiratory tract **, etc., and stay in the human body for a long time to have a negative effect on the human body and heredity, in addition to carbon-14, cesium-137 and other harmful substances.
If the nuclear sewage is discharged into the sea, the fish and shrimp and other organisms in the ocean may cause genetic mutations or death by absorbing and accumulating these radioactive substances, if we eat seafood, it is equivalent to indirectly eating these harmful substances, which may produce chronic diseases, and even damage human DNA, affecting our orthogenetics, my classmates told me that we may be the last normal people in the world, and we may see Godzilla in the future, although we are just talking and laughing, But to dump nuclear sewage into the ocean, all of these things are possible.
To sum up, can you still eat fish and shrimp in the sea? In addition, seawater can also evaporate into water vapor and rise into clouds, which will cause rainfall, which will have an immeasurable impact on the entire ecosystem.
The ocean is so big, can it absorb these harmful substances? In fact, nuclear sewage is completely different from ordinary industrial wastewater, and the harmful substances in it are still decayed for decades even if they are diffused and released in the ocean! Hundreds of years! Or even thousands of years!
We want to protect the ecological environment! We want a warm "home"!

Nuclear wastewater contains a large amount of radioactive substances, mainly including tritium, carbon-14, cobalt-60 and strontium canopy-90, in addition to manganese, glaze, plutonium, cesium and other toxic and harmful substances. The purification of the latter three takes longer. Nuclear wastewater can be diluted, but special wastewater treatment equipment is needed, and the active adsorption device of Eco wastewater treatment equipment can be used to separate the glaze, iodine, plutonium and other reflective substances in nuclear wastewater from water, so as to have a good effect on the degradation of nuclear wastewater to the environment and water sources.
Hazards of Nuclear Industry Wastewater:
1) Oncological diseases.
The incidence of tumors and the residual mortality rate of dead chains are increased by nuclear radiation.
2) Thyroid cancer.
Iodine-131 was the most prominent radionuclide in the early stages of both accidents. It enters the human body mainly through polluted air and food, and accumulates in the thyroid gland through the blood system to participate in normal metabolism. The accumulation of large doses of radioactive iodine in the thyroid gland can induce the development of thyroid cancer.
Children are the most vulnerable group. In two major nuclear leaks, the incidence of thyroid cancer in children increased significantly.
3) Bone cancer, leukemia, circulatory diseases.
The radioactive element cesium-137 can be deposited in bones and can exist for 29 years, eventually inducing the occurrence of bone and surrounding tissue cancer, leukemia and circulatory diseases. Cataracts can also be triggered by exposure to low doses of radiation in children and emergency responders.
