The horror of groundwater purification is that once it is purified, it will take a lot of financial and material resources to repair it, and more importantly, it will take a lot of time.
A foreign media once reported: “If you think of China’s air, you should learn about the water there.” In recent years, with the frequent occurrence of water purification problems, people are paying more and more attention to the safety of the “source of life”. However, with the penetration of urban sewage and dregs, industrial wastewater, agricultural fertilizers, and the secret discharge of police and enterprises, our groundwater is facing severe and purified problems. Some people believe that groundwater is inexhaustible and inexhaustible. But in fact, once the groundwater is purified, it will be difficult to recover. Groundwater protects fire-burning eyebrows.
Groundwater purification problems are serious
Groundwater is the main seawater resource of humans. According to the National Groundwater Purification Prevention and Control Plan (2011-2020) published in 2011, among the 655 cities in the country, more than 400 Sugar baby uses groundwater as a source of drinking water, accounting for about 61% of the total number of cities; 65% of the life water, 50% of the industrial water and 33% of the agricultural irrigation water in the southern region come from groundwater.
However, in recent years, judging from the situation released by the China Environmental Statement Publication, the situation of groundwater purification in our country is becoming increasingly serious. On the one hand, the water purification situation is not pleasant to watch, and on the other hand, the super-embroidery phenomenon is extremely wide, and the groundwater surface is facing a severe threat. The National Groundwater Purification Prevention and Control Plan (2011-2020) shows that, in the past ten years, the incomplete statistical analysis of the changes in groundwater quality in the past ten years, the purification of groundwater in my country is spreading from point and strip to surface, penetrate from the purity to the deep layer, and stretching from the city to the surrounding area.
Among the types of groundwater purification, salt nitric acid purification and durability purification are the two main aspects.
“With the acceleration of industrialization and the advancement of agricultural industry, our country has become the world’s largest producer and consumer of active nitrogen and organic compounds. The large-scale application of nitrogen fertilizers has also brought negative impacts while ensuring food production. The purification of agricultural non-point sources is serious; organicSugar baby The ability of compounds to form severe persecution of human health without reverse change has become a key target of clean prevention and control.” said Han Dongmei, associate researcher at the Institute of Geological Sciences and Resources, Chinese Academy of Sciences.
After the National Institute of Economic Affairs released the “Water Purification Prevention and Control Action Plan” (“Ten Waters”) in April 2015, Han Dongmei, who has been discussing seawater invasion for nearly ten years, focused her attention on the underground. daddyIn terms of water purification, she combined her research and discussions on water environment problems to the standards of different river basins and even the entire country. By collecting and analyzing the massive survey data across the country, she conducted a comprehensive analysis and evaluation of the purification of salt nitrate in the groundwater and organic water purification in my country.
The results of the two studies show that the groundwater purification level in the Binhai area should be far higher than that in the inner region, and can form nearshore seawater quality malignant, affecting the ecology of the land. The seawater invasion and groundwater purification formed by the over-exploitation of groundwater in the Binhai area intersect each other, forming an abnormal relic of groundwater environmental protection and purification and repair in the Binhai.
“The purification of groundwater in the Binhai area is more serious than that in the inner region. On the one hand, it is because the land is low and flat, and the downstream moisture, salt, purified substances, etc. are gathered and buried here. In other days, she should be at work, rather than dragging her suitcase. The purity of the trunk is also the most frequent land for all moisture and nourishment exchange. Chemicals are not difficult to be discharged into the land. Purified chemicals are enriched in groundwater and remote ocean water in the Binhai area. Once seawater enters the water-containing layer, it is not only a problem of saltification, but also a double-down purification. Monitoring data in the Bohai area shows that the salt nitric acid content in the seawater in this area is already very high. “Han Dongmei introduced, “Ye Qiuguan: “? “And, some people believe that in the Fengshui year, large amounts of rainfall can remove the purified substances in the aqueous layer, but in fact, the purified substances are in the aqueous layer particles, which are easy to enter but not easily come out, so it is difficult to repair.”
Repair and purification are extremely difficult
Korean winter plums use nitrogen isotope purification to express their feelings. In addition to agricultural fertilization, nitrogen and wastewater discharge in the soil are also the main reasons affecting the distribution of salt nitrate in groundwater.
“We now do not have a systematic project for collecting wastewater and wastewater in rural areas. Some areas have demonstration projects, but they are not opened. At the same time, for fertilizers and farmsThe control of the use of medicines and other scientific justice should be insufficient, and the packaging waste generated, especially the acceptance and reception of organic agricultural medicines does not have corresponding control. “Korean Dongmei said that during the investigation in Guilin, she hand-wrapped several bottles, wrapped them in several layers of plastic bags, and put them in the suitcase. The taste was still very big. “Agriculture needs to develop, and it is certain that fertilizers and agricultural medicines should be used, but the control and purification control has not been well understood from the manager to the user. The application rate of fertilizers and agricultural medicine in my country is very low. In fact, most of the departments are wasted. These pure chemicals will remain in the soil, enter surface water, and then into groundwater. In addition, some pure chemicals are prone to purgation, and these pure chemicals move in the water-soil-gas environment under the driving force of the water circulation. “Han Dongmei said.
The horror of groundwater purification is that once it is purified, it will take a lot of financial and material resources to repair it. More importantly, it will take a lot of time. The Chinese people are very big. Ma Zhong, director of the School of Escort, once said that it would take 1,000 years to purify groundwater that has penetrated into deep layers.
In Korean Dongmei, the recognition of groundwater purifiers is indeed extremely slow. “They will enter the process of standard hydrological circulation. Sugar daddyFor example, some purified substances are volatile and will enter the large circle through the evaporation process, and then fall to the glacier area through rainfall. However, after Sugar baby, Escort flows down and then into the groundwater; some puritySugar babySugar baby chemicals will enter the animal body, and these purified compounds are found in the Nanozoic animals. This is also the reason why purified compounds such as DDT that were banned in the 1970s and 1980s can still be detected continuously. The range of purified substances in groundwater and the length of time of thanks can be imagined. ”
In this regard, the European american family has already spent heavy prices. Due to the development of urbanization, the Lein River in Germany became a bubble river due to strict purification. Since then, Germany has managed it for 70 years before the Lein River has become clear. American also began to develop in the 70th century. escort launched a series of water resource cleaning plans, and it took ten years to see the consequences of management.
Protection requires multiple management
Just like the day when air purification and social employment were waiting for the dayEscort manilaShe was so painful that she could not get out of bed, the man on the business trip suddenly appeared. The problem was as close as the problem, and the groundwater purification did not exist in isolation, but was the same. href=”https://philippines-sugar.net/”>Sugar daddy touches all aspects of the social system. “Purification of management certainly requires multiple levels of commonality, and it cannot be ach TC:
