Green Printing And Dyeing "New Silk Road"! Foshan Gaoming Promotes Upgrading Of Industrial Printing And Dyeing Park

Entering Cangjiang Industrial Park (Xi'an Area), Gaoming District, Foshan City, a large blue and white building stands in the park. Walking along the new asphalt road of the park, what we see in front of us subverts the traditional impression of the printing and dyeing industrial park: there is no pungent sewage discharge, no black smoke chimney, and no disorderly low factory buildings.

Cangjiang Industrial Park in Gaoming District (Xi'an District) is a microcosm of the transformation and upgrading of Foshan textile printing and dyeing industry. In the sound of high-quality development, Foshan textile printing and dyeing industry is crossing the "pain period" and gradually ushering in recovery

　　 Enterprise "going upstairs": invigorate the use of inefficient land into the common concept of pollution control

Since the 1980s, textile printing and dyeing industry has been one of the pillar industries in Gaoming District of Foshan City. In 2007, Gaoming District was awarded the title of "China Textile Industry Base". In 2021, the industrial output value of Gaoming textile and clothing industry will be 45.143 billion yuan, accounting for 12.25% of the total industrial output value above designated size. There are 37 textile and clothing enterprises above designated size in the whole district, 16 of which are located in Cangjiang Industrial Park (Xi'an area) on the northwest side of Hecheng Street.

However, in the past ten years, while witnessing the continuous development and growth of Gaoming textile printing and dyeing industry, the "pain points" such as low land use efficiency, adjustment of sewage treatment, and difficulty in supervision have gradually emerged, and the "pain" has become increasingly strong

"We deeply realize that the textile printing and dyeing industry in Gaoming District has historical contributions and practical needs that cannot be ignored. How to effectively promote the upgrading of traditional industries, make them better and stronger, and realize the green and low-carbon transformation of local economy and society and the fundamental improvement of environmental quality from the source has become an urgent issue for the development of our district." In the view of District Zhiquan, Hecheng Supervision and Management Office of Gaoming Branch of Foshan Ecological Environment Bureau, Gaoming District is taking the courage and determination to explore the green low-carbon circular development path of textile printing and dyeing industry first.

Starting from the old textile printing and dyeing plants in the Dacheng Road area, Gaoming District has launched a comprehensive renovation of inefficient industrial land, shut down and relocated the original nine printing and dyeing enterprises in Dacheng Road, and integrated into the Qiuying Textile Eco tech Industrial Park, which integrates R&D, weaving, printing and dyeing, sales and logistics with a social capital of 1 billion yuan, Promote the printing and dyeing enterprises to "produce upstairs" to realize the three-dimensional expansion of industrial space, free up 950 mu of high-quality urban renewal space in Dacheng Road area, and realize the centralized development of traditional industries together with the original five printing and dyeing enterprises in Xi'an area of Hecheng Street, Gaoming District.

"Da Da Da......" In the production workshop of Miantai Textile Printing and Dyeing Co., Ltd., the sound of machines is constant, the assembly line runs in order, and workers pick products quickly. "After we settled in Qiuying Textile Industrial Park, the internal energy consumption and water consumption have greatly decreased," said Ding, director of the textile workshop of Foshan Gaoming Miantai Textile Printing and Dyeing Co., Ltd.

It is understood that the "upstairs" enterprises upgrade and use advanced equipment such as low bath ratio dyeing machines, and reduce the use of water, electricity and heat by means of residual pressure and waste heat recovery and variable frequency regulation of electricity, "Through industrial upgrading and integration into Qiuying Textile Industrial Park, enterprises can save up to 4.3643 million kilowatt hours/year of electricity and 110000 tons/year of steam consumption. With a record of enterprise production and operation, enterprises can reduce up to 37.22 million yuan/year of water, electricity, heat and other economic expenditures." District Zhiquan introduced.

　　 Green cycle: promote near zero sewage discharge and implement energy-saving and consumption reduction transformation

For a long time, the traditional textile industry is a typical industry with high energy consumption, high water consumption and high pollution. Especially in the textile dyeing and finishing process, a large amount of wastewater and waste residue will be generated. Improving the level of pollution control is the only way to promote the high-quality development of the traditional textile industry. Therefore, the development of industrial agglomeration is only the first step for Gaoming District to build a "new silk road" of green printing and dyeing. Promoting the full chain governance of water pollution is another key step to promote the upgrading of industrial printing and dyeing parks.

In this context, Qiuying Textile Industrial Park has invested 150 million yuan to build a Lvyuan Water Quality Purification Center with a treatment capacity of 30000 m3/day to collect and treat wastewater discharged by printing and dyeing enterprises in Qiuying Industrial Park and Xi'an District, so as to achieve centralized and high standard treatment of printing and dyeing wastewater in the district.

"The Lvyuan Water Quality Purification Center will be completed and put into operation in 2021, introduce national innovative water treatment technology, and the discharge standard will be 50% higher than that of the industry. After the completion of the expansion project of the reclaimed water reuse workshop, the reuse rate will reach 70%, which will be the responsibility of enterprises contributing to the near zero discharge of sewage in the park." The staff of the Lvyuan Water Quality Purification Center, Gaoming District Party Committee The district government plans to build a "double circulation" system of large circulation (three pollutants - Datang - Lvyuan - surrounding enterprises - three pollutants) and small water circulation (Lvyuan - printing and dyeing enterprises - Lvyuan), of which Lvyuan is the core.

It is worth noting that the park will also rely on the Datang cogeneration project to provide steam, cold water, recycled water and other by-products generated in the process of electricity and power production, and uniformly supply energy consuming enterprises in the park such as Qiuying Textile Eco tech Industrial Park and Runze International Information Port for production, so as to promote the gradual realization of the "multi supply" system of cold, heat, electricity and water in the park, Greatly improve the efficiency of resource utilization.

"In the process of recycling water, the operating cost of enterprises using reclaimed water has been reduced by about 10%, saving 6.47 million yuan/year: enterprises using Datang steam can save 42.43 million yuan/year." Qu Zhiquan said that by fully integrating resources to build regional large and small water cycles, balance the relationship of "water intake - water purification - water use", promote near zero sewage discharge and reduce the production and operation costs of enterprises, The park has achieved "win-win" of environmental benefits and economic benefits.

In Cangjiang Industrial Park (Xi'an area), the construction of "zero direct sewage drainage area" has achieved remarkable results, achieving classified collection and quality treatment of industrial wastewater, domestic sewage and rainwater, and standardizing the drainage of enterprises in the park. In addition, the water environment big data supervision system invested 15 million yuan in the park has covered the main water related units and key rivers in the park. Through the Internet of Things and Internet+, the problem oriented precision and scientific and technological law enforcement has been achieved.

From 2020, Gaoming District will fully tap and integrate resources, optimize and adjust the industrial layout, and promote the green and high-quality development of Cangjiang Industrial Park (Xi'an area) industry through five projects, including "centralized development, centralized pollution control, reclaimed water reuse, unified energy supply, and regulatory improvement"; In 2022, the park will basically complete upgrading and transformation, and become a green low-carbon circular development industrial demonstration park in Foshan with the theme of near zero sewage discharge.

At present, the textile printing and dyeing industry has a long way to go to achieve green transformation. The industry urgently needs to solve the difficulties, eliminate the pain points, and strive to achieve high-quality development in the historical transformation. In the new era and new journey, the textile printing and dyeing industry in Gaoming District will adhere to the non-stop transformation and get rid of the stereotype of "low scattered" and "sunset industry". By promoting the ecological and circular development of the park, it will find a "smart path" to reduce pollution, reduce carbon, and increase efficiency. Through the "platform" of the government and the "singing" of enterprises, it will establish a "smart mechanism" for market capital to participate in environmental governance.
