Present situation of water source of Luanhe River diversion project into Tianjin

The project of "Diversing Luanhe River into Tianjin" starts from Panjiakou Reservoir and Daheiting Reservoir, and enters Yuqiao Reservoir in Jixian County, Tianjin via the main water conveyance canal to the west and Zunhua, with a total length of 234 kilometers. On May 17, the reporter set out from Beijing to inspect the present situation of Luanhe River Diversion Project. The reporter first arrived at Panjiakou Reservoir and Daheiting Reservoir, which are the starting point of Luanhe River Diversion Project and the urban water sources of Tianjin and Tangshan. According to the Notice on Publishing the List of Important Drinking Water Sources in China issued by the Ministry of Water Resources on 20 1 1, Panjiakou Reservoir and Daheiting Reservoir are listed as the first batch of key water sources in China. However, in Daheiting Reservoir, what the reporter saw on the water surface of the reservoir area was dense fish cages, and a large amount of fish feed was put in every day.

Zhang, a farmer from Santunying, Qianxi County, Hebei Province, told reporters that fishermen feed fish twice a day, which will increase to four times a day in the future.

The research shows that the bait and fish manure produced in the process of cage fish culture will sink to the bottom, which will lead to the increase of nitrogen and phosphorus and aggravate the eutrophication of the reservoir. A survey report also shows that the total nitrogen and total phosphorus emissions in the bait and excrement of cage fish culture in Daheiting Reservoir account for nearly 1/3 of the total pollution load of the reservoir every year. However, in such an important water source, many cages have caused water pollution. Due to the large number of cages, local residents can't give an accurate figure. The reporter saw on the water that each cage has a large area. The villagers said that the fish raised in these waters is now the most profitable industry in the village. A villager pointed to his largest flower bud box and told reporters that it contained more than 7,000 kilograms of flower buds, and the estimated output price was around 1.5 million.

According to the reporter's investigation, the local management department not only does not stop cage culture in the water source, but also charges the fishermen. A cage needs to pay 50 yuan money to the local fishery administration department. The national water pollution prevention law clearly stipulates that cage culture, tourism, swimming, fishing or other activities that may pollute drinking water bodies are prohibited in the first-class protected areas of drinking water sources. However, local people revealed that as long as they pay a certain fee, they can raise fish at will in this reservoir. In the two-day interviews with Panjiakou and Daheiting Reservoir, the reporter also saw that there are no landmarks and signs of water source protection areas on the shore, and the people here are unaware of relevant laws and regulations. As for the figure of the regulatory authorities, the reporter has not seen it in the three-day interview.

Qianxi County, Hebei Province, relying on Panjiakou and Daheiting Reservoir, has become the second largest freshwater aquaculture base in North China. Qianxi County forgot all about the water quality of Luanhe River. In the interview, the most talked about by local people is the benefits of farming, but the water safety of thousands of households in Tianjin has never been mentioned. Walking along the river, the reporter entered the Li River in zunhua city, Hebei Province. The total length of the Li River is 76 kilometers, and the Luanhe River Diversion Project borrowed more than 50 kilometers of rivers to transport water here. On May 18, the reporter ended the interview with Daheiting Reservoir and entered the Lihe area of zunhua city. After entering the river, he saw more mining sites and selected iron ore plants on both sides of the river. In addition, tailings silos of different sizes are adjacent to rivers.

The boss told the reporter that due to the rectification of the local government, the iron ore concentrator here has been closed for more than two years, but the local government and the person in charge of the mine are indifferent to how to dispose of the tailings.

It can be seen that although the mine has been suspended for rectification, the tailings piled up on both sides of the river are now the biggest threat to the water quality of Luanhe River. In addition to mining plants, more than 60,000 villagers living along the banks of the Li River also regard the Li River as a garbage dump and sewage pool, which seriously affects the water quality of the Luanhe River into Tianjin. Although Yuqiao Reservoir, which is managed by Tianjin, is near Guohe Bridge, the business of fishmongers is still in full swing. At the busy bridgehead, a management regulation of Yuqiao Reservoir is erected, which prohibits fishing in the river, but these regulations are ignored by fishmongers. A fishmonger told reporters that he basically sells fish on the bridge every day. At noon, some fishmongers have sold their fish and gone home for dinner. Their means of transportation are worn-out diesel boats.

If Yuqiao Reservoir is a few kilometers downstream of He Qiao, 200 kilometers of water from Luanhe River to Tianjin will officially flow into the only centralized drinking water source in Tianjin. According to the Regulations on the Prevention and Control of Water Pollution in Luanhe River in Tianjin, it is forbidden to use explosives, toxic substances or power grids to kill fish and use motorized fishing boats for water fishing in this area; It is forbidden to raise livestock and poultry and engage in intensive aquaculture; But standing on the fruit He Qiao, looking around, there are diesel boats coming and going from time to time, and there are farmed ducks on the water.

In addition, the reporter also saw a very heavy picture under the Guohe Bridge. Around the aqueduct are all kinds of construction waste and domestic waste, and even rotting and smelly animal carcasses can be seen. The reporter walked less than 100 meters along the aqueduct, and the reporter saw several rotting animal carcasses. If you didn't see it with your own eyes, it's hard to believe that this is actually the drinking lifeline of Tianjin130,000 citizens.

On both sides of the bridge, all kinds of warning signs are clearly written, prohibiting fishing, poisonous fish, electric fish, fried fish or swimming in the waters of the boundary area of the bridge reservoir, but just below these warning signs, all kinds of violations are relatively going on. Just less than 30 meters away from this brand, you can see a fish fence in which fishing boats shuttle.

According to the Law on the Prevention and Control of Water Pollution in People's Republic of China (PRC), local people's governments at or above the county level shall, according to the actual needs of protecting drinking water sources, take engineering measures or build wetlands, water conservation forests and other ecological protection measures in quasi-protected areas to prevent water pollutants from being directly discharged into drinking water bodies and ensure the safety of drinking water. However, the reporter found in the village that both sides of the reservoir are farmland and farmhouses. The small river ditch in front of us became a sewage ditch in the village and walked along the river to the reservoir. The reporter saw a large duck factory on the right side of the river bank, and many colorful bottles were piled up on the river bank.

According to public information and research, Yuqiao Reservoir is located in the east of Jixian County, Tianjin, and the surrounding area of the reservoir area involves 7 towns, 16 1 village, population 137073, and cultivated land area is nearly 13000 mu. According to the national water pollution prevention law, if the drinking water source is polluted and may threaten the safety of water supply, the competent department of environmental protection shall order the relevant enterprises and institutions to stop or. A large number of residual chemical fertilizers and pesticides around the reservoir and livestock manure produced by livestock and poultry breeding have caused the reservoir to be polluted to varying degrees, and the water quality here can only meet the national fourth-class water quality standards. Can barely get irrigation and utilization of farmland.
