Xiqiao Textile Industry Transformed Into "Environmental Pioneer"

In the sewage treatment plant of the Sanshui Industrial Park, the switch is turned off, and the water flowing out is clear as tap water and can be drunk directly. And here, the flagship. Spin Printing and dyeing industries are usually regarded as highly polluting industries. The development mode of circular economy has made these highly polluting industries reborn.

Sanshui Datang and the two textile industries in Xiqiao, South China Sea. printing and dyeing Relying on the circular economy mode of "unified water supply, unified gas supply and unified sewage treatment", the town streets gathered by traditional industries provide a model for the green transformation of traditional industries.

One

Environmental protection is productivity.

Xiqiao creates green Famous textile towns It will declare a national circular economic park.

In 2011, the Xiqiao textile industry demonstration base was listed as the provincial circular economy industrial park. Among the first 10 recognized parks (bases), the Xiqiao textile industry demonstration base ranked first.

In the past 7 years, through the "three unification" project, the textile industry of Xiqiao Town, which had been heavily complained, became the pioneer of environmental protection. The environmental revolution has promoted the upgrading of traditional textile industry and revitalized the textile town.

"Three unification" to eliminate waste water

Xiqiao after reform and opening up Textile industry Fame, but the development mode of this big pie mode has also brought Xiqiao textile industry to many crises: the rapid expansion of the industrial scale makes the environmental pressure of the park embarrassed and heavy, especially the large amount of sewage discharged directly, polluting the surrounding rivers and causing great dissatisfaction among the surrounding villagers.

In 2005, the local government decided to invest about 450 million yuan to build the "three unification" project. At that time, it was not understood. Until a few years later, the South China Sea carried out the action of "energy saving and pollution reduction" to be seen as a foresight.

Wu Hanzhao, the responsible person of Xiqiao town textile industrial base, said that the "three unification" project is managed by a professional company, and all enterprises in the park will "unite water supply, supply gas uniformly and treat sewage uniformly". "The surrounding power plants and water plants will transport their surplus water and gas resources to the textile industry base, and the sewage discharged by the enterprises will be collected through the pipelines to collect the sewage treatment plants, and then achieve centralized zero pollution disposal through the centralized treatment of constructed wetlands."

According to him, all enterprises entering the industrial base do not need to invest in the production of small steam boilers, which can greatly reduce energy consumption, save 42 thousand tons of standard coal per year and reduce 8000 tons of sulfur dioxide emissions. The unified water supply also reduces the cost of disinfection of edible water and saves nearly 1/3 of the cost of water for enterprises.

The unified sewage treatment adopts the method of "physicochemical + biochemical + artificial wetland advanced treatment". The industrial wastewater and domestic sewage discharged from the industrial base will be treated uniformly and discharged. "It's hard to imagine that this is a printing and dyeing base with more than 10 thousand employees and a gross value of over 10 billion yuan."

In the end, 44 printing and dyeing enterprises in Xiqiao were included in the "three unification" project. Originally, the sewerage pipes of the printing and dyeing enterprises that had been directly discharged from Xijiang and Beijiang were cut down. The chemical oxygen demand of 5000 tons was reduced by COD in one year, and the emission standard of enterprises was 40% lower than that of the national standard, making Xiqiao textile industry base one of the few in China. textile industry Eco industrial base.

Along with the rapid development of industrial transformation, the data show that in 2009, after the financial crisis, "Xiqiao textile" created the highest rate of start-up in the past 30 years, and introduced more than 1200 advanced textile equipment at home and abroad. The output value, tax revenue and investment trend increased by 9.7%, 19.8% and 36.5% respectively. Today, "Xiqiao textile" loom The total volume has increased from 30 thousand units in 2010 to 40 thousand units.

The growing scale of production has also brought demonstration effects and social effects to industrial parks. There are more than 80 enterprises in Xiqiao textile industry demonstration base. Most of them are excellent enterprises with a certain scale, providing more than ten thousand social jobs.

Will apply for national recycling economy park

Over the past few years, Xiqiao has shut down a group of 13 textile and dyeing factories and other polluting enterprises in the town. It has introduced 17 printing and dyeing factories sewage into the Xinlong sewage treatment plant through the pipe network, and implemented the unified treatment of sewage and clean production. The regional pollution control work has been launched in a comprehensive way. The 165 denim weaving factories in the whole town and 45 enterprises with water looms have been comprehensively improved, and the physical acceptance of 107 boilers in the whole town has been completed.

In order to build a recycling economy demonstration base, based on the "three unification" of Xiqiao textile industrial base in Guangdong, Xiqiao also continues to improve its alkali removal, desulfurization, reclaimed water reuse, green, low carbon and no water. printing and dyeing The construction of circular economy park should be carried out according to the effect of cleaner production technology.

This brings about a three cycle economic chain of the textile industry, namely, the internal cycle of enterprises, the cycle between enterprises and the circulation of industries. The whole process of Xiqiao's house from raw materials, intermediate products to finished products and wastes achieves the optimization and recycling of resources, energy and investment, and vigorously develops multi-level circular economy.

Xiqiao town responsible person said that the next goal is to aim at the national level of circular economy park construction "not for listing, but to take this opportunity to guide enterprises to better develop."

At present, the textile industry base in Xiqiao is making full efforts to expand and extend the textile industry in Xiqiao. This year, Xiqiao will speed up the textile technology headquarters building, the textile industry base life supporting area, and YISHION. clothing Li Feng clothing and other projects. On the other hand, efforts will be made to create provincial green upgrading demonstration parks, implement energy saving and emission reduction measures and clean production measures, and strive to create a national recycling economy park.

Clean up the money.

Green Competitiveness brings real gold and silver to enterprises in Datang Industrial Park

Standing beside a machine in the sewage treatment plant of the Sanshui Industrial Park, the switch is turned off, and the water flowing out is clear as tap water and can be drunk directly. And who can imagine that before the water turned out, it was the industrial sewage discharged from more than 200 enterprises in the park, which was black and smelly.

The Sanshui Datang Industrial Park adjacent to the South China Sea also has many glory such as the circular economy industrial park, the Sustainable Development Industrial Park and so on. Last year, Datang town acquired a national ecological demonstration town, and its circular economy mode of the industrial park has added a lot of color to this obscure town in the process of declaration.

It is worth noting that, similarly, a unified sewage treatment and a unified thermoelectric supply, the environmental protection operator in the big pond Industrial Park is not a government but a textile enterprise in the park.

The Nang Tang Industrial sewage treatment plant, which goes into the Tai Tong Industrial Park, does not have an unpleasant smell. Instead, it has some park ambience under the decoration of green trees and flowers. It is this 140 acre sewage treatment plant that fully accepts the production and domestic sewage in the big pond Industrial Park. Zhang Liangjun, assistant director of the company, told reporters that there were 263 enterprises in the whole Datang Industrial Park, but the daily sewage discharge was only 36 thousand tons.

The main industry of Datang Industrial Park. Textile printing and dyeing Fine chemicals and other industries are usually regarded as the targets of high polluting industries.

In fact, the development mode of Datang circular economy is to some extent forced by the environment. In addition to the environmental pressure brought about by the industrial structure, Tai Tang, located in the sensitive position at the junction of Huadu and Qingyuan, has to attach importance to environmental protection.

The waste water can be reused in the dyeing and finishing process of printing and dyeing enterprises after deep processing of the reclaimed water reuse project. It can effectively control the total amount of pollutants discharge and achieve the reuse of water resources. Beside the big white machine in the workshop, Zhang Liangjun unscrewed the switch with the mineral water bottle, and the water flowing out was very clear. Then he drank the water in the mineral water bottle before reporters. "This water is the black sewage that you just saw treated through the reclaimed water reuse system." Zhang Liangjun introduced that after the reclaimed water reuse system, all the components in the water will be filtered and can be drunk directly. "There is no mineral in it. It is cleaner than pure water."

As for the cost of reclaimed water, he calculated an account. "The cost of ozone treatment for 1 tons of water is 5 to 6 cents, while the reverse osmosis treatment costs 1 to 1.3 yuan, and the combined cost is almost the same as that of tap water.

In addition, Sanshui big pond more than 70 homes. Textile enterprises All through the thermal power plant for unified heating.

For the benefits of central heating, Zhang Liangjun said that from the point of view of energy saving, the large capacity chain boiler adopted by the thermal power plant is 7 to 5 of the standard coal production capacity compared with the ordinary small boiler. According to the existing scale, it can save about 340 tons of standard coal per day, and "use trucks to install a fleet."

Number reading

44 printing and dyeing enterprises in Xiqiao were included in the "three unification" project, which reduced 5000 tons of chemical oxygen demand COD in one year, and the enterprise emission standards were 40% lower than the national standards, making Xiqiao textile industry base one of the few textile industrial ecological industrial bases in China.

In April 2010, the thermal power plant of glida has built 2 35 tons / hour, 1 sets of 75 tons / hour and 1 130 ton / hour boilers, and equipped with 18 thousand KW generating units to achieve centralized steam supply in industrial parks, and successfully integrated into the Guangdong power grid.

Environmental protection operators

Jia Lida: textile manufacturer

In Yao Ying's view, the textile industry and Environmental protection cause It's like two ends of a balance. "At the very beginning, we mainly engaged in textile printing and dyeing technology, but now we are more inclined to the development and utilization of sewage treatment plants and thermal power plants."

Yao Ying is the chairman of Foshan Sanshui Jia Lida textile printing and dyeing Co., Ltd. The company that he steered is the leading company in Sanshui big pond Industrial Park, and is involved in textile, dyeing, thermoelectricity, sewage treatment, tap water supply and many other business areas. Its staff number exceeds 1500, and last year the tax amount exceeded 50 million yuan.

In the early days of garida's entry into the Datang Industrial Park, the daily treatment capacity of the sewage treatment plant in the park was only 9000 tons, and the daily water supply capacity of the water plant was only 20 thousand tons, which was difficult to meet the needs of the enterprises in the park to increase investment and expand production capacity. After the construction of the thermal power plant was completed half of the project was shut down for some reason, it became a "half baked" project, and the central heating plan in the park was temporarily stranded.

Under such circumstances, Jia Lida and other textile enterprises in Datang Industrial Park can only build their own boilers and supply the steam needed for their production. And this "self-sufficiency" way is actually costly and inefficient, and it seems to be stretched under the growing demand.

To this end, Yao Ying smashed heavily to acquire thermal power plants, sewage treatment plants and water works. "We think that the environmental requirements of the city will be stricter and stricter. It is a general trend for enterprises to migrate to the park and concentrate on the outside, so we gambled once."

From 2006 to 2009, the annual investment of Jia Lida was between 150 million yuan and 200 million yuan, and three factories totaled more than 600 million yuan each year. In April 2010, the thermal power plant of glida has built 2 35 tons / hour, 1 sets of 75 tons / hour and 1 130 ton / hour boilers, and equipped with 18 thousand KW generating units to achieve centralized steam supply in industrial parks, and successfully integrated into the Guangdong power grid.

The sewage treatment plant has built a capacity of 56 thousand tons / day for the design and treatment of industrial sewage, 3.8 tons / day of reclaimed water, and a daily water supply capacity of over 100 thousand tons.

From textile manufacturers to environmental operators, Jia Lida found a vast market of new blue ocean.
