History of Binan River in Bishan, Chongqing

Binan River, with a total length of 73km and a drainage area of 44 1 km2, runs through the whole territory from north to south, involving 7 towns and streets in Bishan, and is the largest secondary river in Bishan County. In recent 10 years, with the rapid development of economic construction in Bishan county, industrial enterprises on both sides of the strait have developed rapidly and the number of large farms has increased. In addition, the domestic sewage from towns in the basin was directly discharged into Hanoi without treatment, and the clear river water began to turn black. In some river sections, pig manure and duck manure have covered the river, and the river has become worse than Class V, giving off a stench. Not only the river is polluted, but also both sides of the river bank are polluted and the ecology is destroyed. The pollution of Binan River has seriously affected people's daily life. This river not only stinks, but also can't meet the basic requirements of irrigating farmland. Residents living by the river are afraid to open the windows. Binan River has become synonymous with "dirty and smelly" and has become the pain of Bishan. The common people joked that Binan River is comparable to calligrapher's washing Mo Chi. In 2007, Bishan County of CPPCC conducted a special investigation on the pollution situation of Binan River according to the reflection of ordinary people. The feature film reflecting the pollution situation of Binan River in the investigation surprised the county leaders. "If you don't manage Binan River well, you will be ashamed of 600,000 villagers in Bishan!" Faced with the grim facts, Fan Mingwen, secretary of Bishan County Party Committee, and Wu Daofan, county magistrate, promised to treat the pollution in the whole basin of Binan River in two years, and then to treat it normally in two years. The transformation began at the end of last year. Since June 5438+February, 2009, Bishan County has carried out a massive Binan River regulation project, relying on scientific governance methods and legal governance models to implement "iron fist regulation". In just a few months, the once extinct fish and shrimp have returned to the river, surrounded by willows and parks, and Binan River has become a beautiful new landscape. The data show that the overall water quality of Binan River has changed from inferior grade V to current grade IV, and the COD value of 68 main tributaries 19 section in the basin is less than or equal to 30 mg/L, which meets the requirements of national grade IV water quality standards. In the next three years, the water quality will become Class III or even Class II. Binan River is really clear! "Look! Another big fish! " In the Mid-Autumn Festival, on the Binan River, an old man in Yu is wearing a straw hat and fishing leisurely. Fishing with fishing friends by the river has become his most enjoyable thing. Nowadays, the clear Binan River is gurgling, and the scene of fishing and fish swimming by ten thousand people is in sharp contrast with the dirty, chaotic and smelly past. "Don't talk about fishing before. Putting fish in the river is a' death sentence' for fish. " Yu said. From August to September this year, the relevant departments of Bishan County released10.5 million kilograms of large-scale fry into the treated Binan River for three times. In recent months, the fish began to grow, and many fishing enthusiasts were seen on both sides of Binan River. At the same time as the river became clear, the ecology on both sides of the strait began to recover. Nanhe Park, Sing Tao Park and Wetland Park will be newly built along the Binan River in Bishan County. In the past, trees and flowers have been planted on the river banks with soil erosion. Plant aquatic plants such as water hyacinth, water lily and wick in the upper reaches and tributaries of Binan River to purify water quality and stabilize soil. "Next spring, we will plant green bamboos on both sides of the river," said the head of the county environmental protection bureau. Before the treatment, the people also complained about the pollution sources on both sides of the Binan River. Therefore, in the process of governance, Bishan County should start with blocking the source and remove the pollution sources on both sides of the strait. At present, in addition to closing more than 30 key polluting enterprises and dismantling more than 200 large-scale farms, most of the river sections have also been cleared of silt. Before the renovation of Binan River, villagers in Datang Village, Bicheng Sub-district Office had to close their doors to eat because of the pollution caused by a large aquaculture spot along the river, and could not wash their hands and feet in the river. The water in the river cannot even be used to irrigate farmland. Now, villagers can not only irrigate vegetable fields with river water, but also wash clothes in the river. Zhang Xiaohe, former vice chairman of CPPCC County, lives near Binan River in the city and suffers from pollution from Binan River. In order to control Binan River, he led CPPCC members to investigate the pollution situation of Binan River for many times and made suggestions to the government. Now that the treatment has achieved initial results, he is very pleased. He often goes to the river to watch the water quality changes, actively publicizes the effect of treating Binan River to the public, and encourages everyone to contribute to pollution control. "Although the management of Binan River has only achieved phased results, it has won the support of the people." The person in charge of the environmental protection bureau of Bishan County said that a recent poll in the county showed that people's satisfaction with Binan River has increased to over 90%. The masses spoke highly of the government's iron fist management of Binan River. The Binan River has become clear, the pollution sources have been cleared, and the results of phased management have been recognized. At the same time, it also stimulated social environmental awareness and consciously protected Binan River. Bishan Hongqi Cylinder Head Manufacturing Co., Ltd. is a machinery manufacturing enterprise. Encouraged by the management of Binan River, he also actively participated in pollution control. 1. The company promises to the people of Bishan County in the media: to ensure that the company's production wastewater reaches the standard and does not pollute Binan River. Subsequently, 6.5438+0.2 million yuan was invested to build sewage treatment facilities to treat production wastewater. "At present, the industrial enterprises in Bishan are consciously doing a good job in pollution control under the encouragement of the control effect of Binan River." The person in charge of the Environmental Protection Bureau of Bishan County said that more than 70 industrial enterprises that failed to meet the environmental protection standards in the past have invested in environmental protection facilities such as sewage treatment according to environmental protection requirements, so that the production wastewater can meet the standards. "Through the management of Binan River, the environmental awareness of the people in the county has been enhanced." The person in charge of the county environmental protection bureau said that due to the determination of the county party Committee and the county government to govern the Binnan River, in the governance of the Binbei River, polluting enterprises and large-scale farms in the basin have been consciously shut down and dismantled. Binan River, the mother river of Bishan. "Water is as black as ink" used to be its true portrayal. This river can't be used as a source of domestic water, and it is also difficult to control, which has seriously affected the lives of ordinary people. From June 5438 to February 2009, the pollution control of Binan River was fully launched. The county party committee and government have set the governance goal of "achieving obvious results in one year and basically reaching the standard in two years". Relying on scientific governance methods and legal governance model, the Binan River has undergone earth-shaking changes in just half a year. Today's Binan River is not only clear, but also full of green on both sides, which provides a reference for the management of urban secondary rivers. & lt/p & gt； & lt/p & gt； & lt/p & gt；
