The hottest pollution control road in Liuzhou, Gua

In late autumn, the Liujiang River passes through the city from Liuzhou, Guangxi. The river is clear and quiet, forming a beautiful picture of "a bay of clear water passes through the city, and ten miles of green mountains and a half into the city" with the surrounding scenery, indicating that Canada's plastic recycling industry has made significant progress. Perhaps, people in Liuzhou more than 20 years ago would not have thought that this heavy industrial city, which once smoked heavily and even sparrows would turn black when flying, now has 308 days of annual excellent air quality. Together with the pink Bauhinia flowers blooming all over the city in spring, Liuzhou has formed a livable new landscape of spring flowers and autumn waters. People living here also increasingly feel the poetic dwelling

refuse the "city of acid rain" and the "iron fist" pollution control road is firm and solid.

when it comes to Liuzhou, many people's impression stays in the industrial city. Indeed, as an old industrial base, Liuzhou has an industrial history of nearly 100 years. Industries such as steel, machinery, chemical industry, cement, thermal power, papermaking, automobile, etc. give the city a unique temperament and glory. However, the extensive development mode dominated by heavy chemical industry for decades has also caused serious environmental pollution, leaving an unavoidable shackle and depression to the city

according to the memories of many elderly people in Liuzhou, the 1980s and 1990s were the most serious period of pollution in Liuzhou. At that time, there were many chimneys in the urban area, thick smoke billowed, pedestrians covered their noses and rode bicycles in the streets, behind the smelter was "Baitou mountain", under the Panlong mountain was "black waterfall cloth". The sewage from more than 30 sewage outlets in the urban area directly drained into the Liujiang River, where dead fish floated, sewage from zhue river flowed, and crops from farmland and vegetable fields fell down

the pattern of "factory in city, city in factory" makes the concentration of sulfur dioxide in the air seriously exceed the standard, and the annual acid rain rate is as high as 98.5%, resulting in the pollution phenomenon of "ten rains and nine acids". At that time, leafy vegetables and grapes could not even be planted in the suburbs of Liuzhou, because as long as it rained, the leaves would rot, and the bicycle would rust after being exposed to the rain. Because of the flooding of acid rain, Liuzhou has become one of the four "acid rain cities" in the country, and the production and life of citizens have been seriously affected. The economic losses caused by acid rain and the cost of passive response and treatment are as high as billions every year

Liuzhou, it's time to make a change. After a nationwide heated debate on "whether to Liuzhou or Liugang", finally, "both Liuzhou and Liugang, but also clear water and blue sky" became a unified consensus

pollution control starts with acid rain treatment. Since 1991, Liuzhou municipal Party committee and government have taken green development as an important assessment indicator. In 1992, the fluidized bed boiler, an industrial boiler with backward technology, was forcibly eliminated in the city. In 1993, 23 enterprises with heavy pollution and high energy consumption were organized to prepare and complete the pollution source prevention and control plan for key enterprises. 199 except that some raw materials and products were affected by the rapid expansion of production capacity, showing weak price growth, high sulfur, high ash and low-quality coal was strictly prohibited from entering the city in the past nine years. Establish a sulfur dioxide emission permit management system, issue sulfur dioxide emission permits to more than 100 key monitoring enterprises of sulfur dioxide pollution sources, and incorporate all key sulfur dioxide emission sources in the total amount control zone into effective monitoring and management. Under a series of strict regulations, Liuzhou's sulfur dioxide pollution control work is in the forefront of the country

in 2006, Liuzhou zinc plant was closed. For Liuzhou, this is a major event. Established in 1951, this old enterprise with a series of zinc oxide output ranking first in the world is a "cash cow" in Liuzhou. However, due to excessive emissions of waste gas and liquid for many years, it has seriously affected the lives of citizens and the urban environment. The municipal Party committee and the municipal government resisted the huge pressure and ordered the enterprise to shut down production in the original factory

besides acid rain control, air quality control and comprehensive environmental control of urban river sections have also been steadily followed up

in the past, there were "yellow dragons" formed by industrial waste gases wandering over Liuzhou all year round. At the beginning of 2006, Liuzhou people were surprised to find that the "Yellow Dragon" that had wandered over the city for nearly 40 years finally disappeared, and they ushered in a long lost blue sky. Behind this is the integration and reorganization of the pollution industry in Liuzhou: technological transformation, remote reconstruction or expansion of traditional old enterprises; We will resolutely shut down some heavily polluting enterprises that have no hope of treatment, have serious pollution and affect people's lives; Take the lead in establishing PM belt protective cover [universal material testing machine] in Guangxi. The company promises: 2.5 monitoring system, and the monitoring data will be released to the society every day. Over the years, the number of days with excellent air quality in Liuzhou urban area has maintained a good trend. In 2017, the excellent rate reached 84.4%, and the annual number of days with excellent air quality reached 308

Liujiang River is the mother river of Liuzhou, and 92% of the production and domestic water of Liuzhou city comes from Liujiang River. In the past, most of the wastewater formed by urban production and domestic water was directly or indirectly discharged into Liujiang River. In order to thoroughly improve the water quality of Liujiang River, Liuzhou started the "iron fist" water control and comprehensively launched the "strictest" sewage discharge access mechanism in history. Today, the once black and smelly water body has become clear to the bottom. The Liujiang River drinking water protection river reaches the national surface water quality standard of class III all year round, and some reaches the class II water quality standard. In 2016, the water quality compliance rate of Liujiang River environmental functional area was 100%, ranking first in the water quality evaluation of 93 key river sections of 37 rivers in Guangxi, and becoming a model for river treatment in industrial cities across the country

in this way, through unrelenting, real ammunition and step-by-step treatment, Liuzhou got rid of the shackles of heavy pollution and wrote a miracle of green development of industrial cities

embrace "livable Flower City" life in this city is getting happier and happier

this spring, Liuzhou was covered with Bauhinia flowers, and tens of thousands of people went straight to Liuzhou to take photos of 270000 Bauhinia flowers. Flowers in the city, the city in the flowers, the full bloom of Bauhinia, let people remember the pink sea of flowers, but also let people know the city again

step by step, step by step, after continuous pollution control, at the end of the "Eleventh Five Year Plan", Liuzhou threw off the hat of "acid rain city" and entered the "Twelfth Five Year Plan" stage. Liuzhou's air quality continued to improve. The city's forest coverage increased from 63.2% in 2010 to 64.9%, and the green space coverage of urban built-up areas increased from 40.37% to 43.19%. Liujiang River maintained the national class III standard for surface water all year round

in the past, in order to control pollution, Liuzhou gave up the development path of heavy industry. People once worried about whether this would have an impact on economic development. Over the years, with the continuous improvement of the ecological environment, this concern has also dissipated. In 2015, the total GDP of Liuzhou city was 229.862 billion and the total industrial output was 454.125 billion, both of which were double that of 2010. In 2017, the city achieved a regional GDP of 275.564 billion, an increase of 7.3%; The total industrial output value was 511.614 billion, an increase of 7.5%; Industrial profits above Designated Size reached 18.507 billion, an increase of 40.57%. Under the guidance of the concept of green development, Liuzhou's economy has not only not declined, but also moved steadily forward on a green, healthy and sustainable road

as a representative enterprise of Liuzhou industry, Liuzhou Steel has made great contributions to the economic development of Liuzhou since its establishment in 1958, and is a banner of Liuzhou industry. However, due to backward technology and equipment, serious pollution and poor environment, Liugang plant was jokingly called "even the sparrows flying are black". "If Liugang does not do a good job in environmental protection, it will not even have the right to survive." Under the guidance of this concept, Liuzhou Iron and Steel Co., Ltd. has invested more than 7 billion in the past decade to build more than 50 technologically advanced energy-saving and environmental protection projects, including centralized treatment of industrial wastewater, full desulfurization and dry quenching of sintering pellet flue gas, dry dedusting of converter and blast furnace flue gas, ultra-fine water slag powder, and hot stewing of steel slag. The problem of "three industrial wastes" that once made Liugang headache, now the residual heat can be recycled for power generation, all wastewater is intercepted and reused, and all waste residues are comprehensively utilized. A series of new energy-saving and emission reduction technologies have enabled Liugang to find new growth points in the circular economy. Today, Liuzhou Iron and Steel Group has increased its production capacity from 1million tons to more than 12 million tons, but its pollution emissions have been greatly reduced

from the former "big polluter" to today's "green steel enterprise", nature gives the best answer. Recently, the staff took a summary report on the design, construction and acceptance process of passive houses in Liugang plant to the figure of egrets, a national second-class protected animal. It was black that even sparrows flew by, and there was egrets, a national second-class protected animal. Queshan Park, separated by Liugang wall, has also become a "paradise for birds". Every year, a large number of foreign photography enthusiasts come to shoot kingfisher and egrets, This is the most beautiful picture of the harmonious development of Shanshui City and green steel enterprises
