What is the extent of water pollution in China?

In today's China, there is absolutely no need to spend so much effort. More and more people are already abandoning tap water and buying mineral water and purified water. There are even column articles saying: Tap water in some cities only has the function of flushing toilets.

The outbreak of water pollution accidents in Lanzhou in April this year shocked the country. The general causes and local government response methods were similar to those of similar accidents in some cities. According to reports, a box of water in Lanzhou rose to over a hundred dollars.

Such an event will not be the last and it will never be the worst. Experts have long predicted that water pollution in China is more serious than air pollution. There will be extreme water pollution accidents.

First, the big rivers are all stained

Since 1993, the author has interviewed the pollution of Dianchi Lake and Taihu Lake for three times along the Chongqing-Wuhan section of the Yangtze River, once from the source of the Yellow River to the mouth of the sea, and once along the Huaihe River from Anhui to Henan. There is some understanding of the facts about water pollution in China. Here are some areas to illustrate:

Is China's water pollution serious?

The first is the Huaihe River.

In 1995, the Chinese government promulgated the "Interim Regulations on the Prevention and Control of Water Pollution in the Huaihe River Basin" in the form of a State Council decree, which explicitly requires that the water quality of major river sections, lakes, and reservoirs in the Huaihe River Basin meet the requirements of the Huai River Basin water pollution control plan in 2000. Huai River water body to achieve clear. Has the Huai River become clear today?

Let me say Shanghai.

Shanghai is China's most modern city with the highest level of management. However, from 2003 to 2013, the author spent a decade in prime locations in Shanghai, fearing Shanghai's strong smell of running water. From Shanghai to the bustling and beautiful Yangtze River Delta, from the ditches in the fields, to the tourist resorts in Zhouzhuang and Shaoxing, and to look at the black water that smells bad, what detection data are needed to explain the general and serious pollution levels? ?

Talk about the Yangtze River.

Travel by boat along the Yangtze River, and then in Chongqing, Yichang, Wuhan and Other cities around the week, look beyond the shock. Numerous sewage outlets are like dragons. They sneeze venom on the Yangtze River all day long. Numerous piles of rubbish are piled along the river and piled up. They will naturally slide into the Yangtze River. The river will rise and it will naturally bring rubbish into the river. The pollution control experience of the mega-corporations is: Extending the sewage outlet to the heart of the Yangtze River, they said: This is called making full use of the river's self-purification capability. For people living along the river, the unfortunate part is that the Yangtze River is the main source of wastewater for the towns along the river, and it is also the main source of drinking water for people.

Talk about the Yellow River.

One of the benefits of the large sediment content of the Yellow River is its great ability to cleanse. The Yellow River, which was heavily polluted in Qinghai, purifies itself in the course of flowing into the Liujiaxia hydropower station reservoir area. After precipitation, a type of water quality flows out of Liujiaxia. However, after just a hundred kilometers, when it entered Lanzhou, it became three types of water. When it flowed out of Lanzhou City, it became four types of water, and after flowing through Baiyin City, it fell into five types of water. A large number of industrial and domestic wastewater are continuously discharged into the Yellow River.

The Ministry of Water Resources has evaluated the quality of water resources in more than 700 rivers and about 100,000 kilometers of rivers across the country. The result is that 46.5% of rivers are polluted and the water quality only reaches the fourth and fifth categories; 10.6% of rivers are seriously polluted. The water quality is super five and the water body has lost its use value; more than 90% of urban waters are seriously polluted. Water pollution is developing from the east to the west, extending from the tributaries to the main stream, spreading from the city to the countryside, infiltrating from the surface to the ground, and spreading from the area to the basin.

The former State Environmental Protection Agency has issued a press release: Among the seven major river basins in China, the major problems faced are water pollution and water shortages. The main rivers have widespread organic pollution, and the major lakes are seriously eutrophic.

The order of pollution of the seven major river systems from heavy to light is: Liaohe River, Haihe River, Huaihe River, Yellow River, Songhua River, Pearl River, and Yangtze River. Among them, more than 70% of the river sections in the Liaohe, Huaihe, Yellow and Haihe rivers have been polluted.

Second, a serious cause of water pollution

Speaking of the causes of serious water pollution, Qu Geping said: "It is mainly affected by three factors:

Is China's water pollution severe enough?

The first is industrial pollution, which is very serious. In the future, even if all industries have a reasonable layout, all the sewage will meet the discharge standards, and the treated sewage will also be of the super five category.

Second, urban domestic sewage, it will take a long time for China to completely discharge after treatment.

Third, non-point source pollution, that is, nitrogen, phosphorus and other pollution caused by chemical fertilizers, pesticides and soil erosion in farmland. This problem is more troublesome. China is the country with the highest chemical fertilizer use in the world. Compound pollution caused by various factors will make the deterioration of water pollution in China more and more serious. ”

Is China's water pollution severe enough?

Experts believe that there are several other reasons for the following reasons: First, the overall level of economic and social development is low, and the level of social management is low. Second, some so-called entrepreneurs have low moral standards.

Why do you say that? In developed countries, the reuse rate of industrial water reaches over 80%. And the sewage must be treated to meet the standard discharge. The reuse rate of water in China is much lower than this. Most enterprises do not meet the discharge standard after the sewage is completely treated.

On average, every 10,000 people in developed countries have a sewage treatment plant that processes the daily sewage produced by people. In China, until the mid-1990s, there were less than 5 domestic sewage treatment plants in China. The majority of large cities such as Wuhan and Chongqing have zero domestic water treatment. All are direct emissions.

Until today, no city in China has yet 100% sewage treatment.

The reason for the low level of entrepreneurial morality is based on the author's many years of unannounced visits, pits, sneak attacks, and arrests of those who have been guilty of illegally discharging sewage.

China's pollution control technology is already behind, but if it is strictly enforced, it can also be used. However, for so many years, there have been many companies that have seen the discharge of sewage, and I really do not have confidence in how many companies strictly enforce environmental protection laws and regulations. Because the cost of starting a pollution control facility is high, black-haired entrepreneurs often steal. From this point of view, there is no evidence that there are companies that discharge pollutants into deep wells. However, the author firmly believes that this has done so.

The problem of water pollution is indeed a very tricky issue. The interests are complex and complex. It is a slow and long-term process to achieve complete improvement. But you can't always wait until that day! However, what we can do is to filter the tap water flowing from the tap in the house, drink clean, safe and healthy water, and have the water purifier installed?
