The ecological ＂attack＂ of Hukou, Jiangxi Province： both internal and external repairs refresh the ＂face value＂ of the Yangtze River coastline

　　Jiujiang, Central Broadcasting Network, July 14 (Reporter Jing Wong) In the evening, many employees of Guohua Jiujiang Power Plant in Hukou County, Jiangxi Province are always willing to come to the nearby pier section to bend. "There are river winds, many trees, good air and very cool." They have worked and lived by the Yangtze River for decades and are very sensitive to the changes in the Yangtze River. "In the past, there were small, scattered and chaotic illegal docks and berths on the shore, which were dusty and smoky."

　　The Yangtze River gives Hukou a coastline of only 24 kilometers, starting from Shi Zhongshan, the intersection of rivers and lakes, to Shazhou dike at the junction of Pengze Hongguang Wharf. Hukou County is located at the junction of Jiangxi, Anhui and Hubei provinces, and it is named because it is located at the only intersection of the Yangtze River and Poyang Lake. At present, the Yangtze River is in flood season, and the water level in Hukou basin is also rising continuously. The car drove near the dock section of Guohua Jiujiang Power Plant. The reporter saw rows of poplar and bamboo leaves and willows on the other side of the river growing vigorously, becoming a bright green barrier along the river.

　　Embroidering the most beautiful coastline of the Yangtze River by "pricking" and "healing"

　　Up to now, at the entrance of Guohua Jiujiang Power Plant, such a group of old photos are still posted: freight ships are scattered all over the Yangtze River, the support approach bridges are criss-crossed, and waste residue is piled up all over the ground; The dock owner illegally built the berth and occupied the shoreline green space as a warehouse. ……

　　"Illegal docks, like psoriasis, erode the coastline of the Yangtze River. If not rectified, it will directly affect the flood discharge capacity of the Yangtze River and the navigation safety of the waterway, and seriously damage the ecological environment along the coastline." In order to protect the Yangtze River water, Zhang Ping, director of the Development and Reform Commission of Hukou County, Jiujiang City, Jiangxi Province, told the reporter that 13 illegal docks along the Yangtze River and the lake were demolished and 7 small scattered pollution chemical enterprises were shut down. "Last year alone, 35 local projects with high environmental pollution and high energy consumption were rejected, and three projects under construction were urgently stopped."

　　During the visit to Hukou along the Yangtze River, the reporter saw that the docks on both sides of the strait were produced in an orderly manner and the trees were green. The slogan "Building the most beautiful Yangtze River" appeared on the buildings on the shore from time to time.

　　After "subtraction", it is necessary to "add". According to Zhang Ping, at present, Hukou County will divide 24 kilometers of coastline along the river into urban landscape belt (2 kilometers), green belt along the river (9 kilometers) and park ecological belt (13 kilometers) for planning and upgrading.

　　At present, the dock section of Guohua Jiujiang Power Plant, which is known as the "most beautiful coastline" demonstration section of the Yangtze River at the mouth of the lake, is surrounded by poplars and weeping willows. At the top of the embankment, the original bumpy dirt road was changed into a high-standard asphalt pavement; Within the dike, heather and other colored shrubs are colorful … The 3.5-kilometer-long scenic belt along the river has taken shape.

　　But these are just one of the shots for Hukou to create the "most beautiful coastline" of the Yangtze River.

　　Facing the reporter, Xia Minqian, deputy secretary of Hukou High-tech Industrial Zone and director of the Management Committee, is a few treasures: "While greening and beautifying the coastline along the river, we have adopted technical measures such as gabion protection, slope retaining wall, native tree transplantation, hanging net and spraying, etc., and carried out ecological restoration on 30 exposed mountains with a total area of more than 600,000 square meters along the river, and the ecological environment of the park has been significantly improved."

　　Abandoning "Black and Dirty" and "online celebrity" Steel City to Realize a Win-Win Economy and Ecology

　　Jiugang, located by the Yangtze River. It is bordered by the Yangtze River Golden Waterway in the north, Poyang Lake in the west and pengze county in the east, which can reach Anhui Province. Daily production will inevitably produce industrial wastewater and waste gas, which will directly affect the ecological environment of the Yangtze River if it is not handled properly.

　　It lasted for nearly a year and a half. When the reporter came to Jiugang (Jiujiang Pinggang Iron and Steel Co., Ltd.) in Hukou County, Jiujiang, Jiangxi Province again, he found that it was different from the past and the appearance of the traditional steel city. It had already been covered with "green clothes", the rainbow bridge was set up on the barren river beach, and the yellow land became a landscape line … and an "eco-forest tourism factory" was built with an investment of more than 1 billion yuan.

　　As soon as you enter the factory, you can see a white wall building decorated with geometric lines along the blue pipeline covered bridge in the air. This is Jiujiang Iron and Steel Tourist Service Center. In the immersive VR experience hall, you can experience watching the steelmaking process with naked eyes; The factory also designed a tour route of "How steel was tempered" to create an industrial scenic spot; The distinctive "Sanjiang Tower" was built on Pier 3 of Fangda Jiugang, which is next to the Yangtze River. The tower can overlook Anhui and other places, so it is named "Sanjiang". ……

　　But in the past, this was not the case here.

　　There are metallurgical and chemical enterprises in Hukou High-tech Industrial Park where Jiugang is located. In the past, the pollution was serious, and the park was always shrouded in gray. Chen Zhenyu, head of the environmental protection department of Jiugang, felt deeply about this. "In the past, when I went to work, I was gray in sunny days and muddy in rainy days."

　　In order to protect the spring water in one river, Jiugang has invested nearly 100 million yuan in reconstruction projects such as recovery and treatment of flue gas water in Shangma Steelmaking Plant and secondary cooling water in steelmaking converter, and built two on-line wastewater detection stations to monitor wastewater discharge. "After treatment, the water intake per ton of steel in enterprises has dropped from 2.33 cubic meters in 2016 to 2.16 cubic meters at present, and the wastewater discharge per ton of steel has dropped from 0.98 cubic meters in 2016 to 0.46 cubic meters at present, which is far below the implementation standards of iron and steel joint ventures. The treated wastewater can be used for fish farming." Speaking of which, Chen Zhenyu revealed his pride on his face.

　　"Although a lot of financial resources have been spent on environmental protection, it is rewarding in economic benefits." A person in charge of Jiugang said that in 2017, the per capita steel production of Jiugang reached 1,048 tons, and the profit per ton of materials ranked second in the industry, and the per capita income of employees (excluding middle and high levels) reached 147,600 yuan.

　　"We use Yangtze River water for production, and the quality of the discharged water is higher than that before use." In the sewage treatment observation pool of Jiugang, the reporter saw lotus leaves floating on the treated water surface. According to the staff, there are many fish creatures in it. "Biology is the best ‘ Water quality inspector ’ 。”

　　According to reports, Hukou County has invested more than 50 million yuan to upgrade the sewage pipe network, sewage treatment plant and intelligent monitoring system in the park to ensure that each enterprise has a monitoring system and centralized supervision in different districts. "The intelligent monitoring system automatically samples every 2 hours and conducts on-site analysis. If the data exceeds the standard, the electric valve will automatically close and the wastewater will flow back to the sewage collection pool of the enterprise." Zhou Bo, director of the Monitoring Center of Hukou County Environmental Protection Bureau, said that through these facilities, enterprises are encouraged to increase investment in environmental protection and truly meet the discharge standards.

　　Last year, Jiugang once strived for a national 4A-level tourist attraction, which will be opened to the outside world for tourists in the future.

　　And these are just a silhouette of Hukou to create the most beautiful Yangtze River coastline.
