1. Research on cooperation projects between the institute and enterprises
Solve the problem of sludge disposal in the textile industry
The textile and garment industry is a traditional technology pillar industry in Foshan. At present, there are 12,470 productive industrial and commercial households in the city, including 898 enterprises above designated size. In 2011, enterprises above designated size achieved a total industrial output value of 120.2 billion yuan, accounting for 7% of the city's total industrial output value. The printing and dyeing industry is a technology-intensive and indispensable important link in the prevention and control of the garment industry.
It is an important link in industrial transformation and upgrading, but for many years, the printing and dyeing industry has had the problem of difficult sludge disposal. According to the statistics of Foshan Textile and Apparel Industry Association, the production of printing and dyeing sludge in the city is 200,000-250,000 tons per year (calculated with a water content of 80%), and most of them still use "concentration + belt filter press dehydration + outbound landfill" dispose of
With the prominence of urban environmental problems and the needs of the development of the textile and garment industry, traditional sludge treatment methods have gradually exposed their drawbacks. And to solve the sludge problem through a qualified printing and dyeing sludge disposal unit, enterprises often have to bear huge costs." Feng Zhuquan
It is said that after the deep dehydration project transformation, Jinfang Group will produce about 20 tons of sludge (about 60% water content) every day. If all the processing is entrusted to a qualified unit, the annual transportation and disposal fee will exceed 3 million yuan.
A scientific and technological innovation project led by Foshan Environmental Protection Technology and Equipment R&D Industry Center came into being. Through in-depth research on sludge disposal in Foshan's textile and garment industry, it is discussed to solve the development problems faced by enterprises by scientific and technological means. "We will cooperate with Foshan Garment and Textile Industry Association to find cooperation with textile enterprises above designated size in Foshan, and form a project to carry out the research and application of sludge control technology for sludge mixing project (hereinafter referred to as sludge mixing project)." The person in charge said that the participating enterprises need to have the basic conditions to carry out sludge blending with coal, including supporting the construction of thermal power stations, generating electricity and gas supply through Rao coal boilers.
Foshan Shunde Jinfang Group Co., Ltd. is currently facing the actual needs of sludge disposal. As a cooperative pilot enterprise of the printing and dyeing sludge mixing project, the company has fully cooperated with the scientific and technological innovation work of the professional center since the project was established in August last year. The hardware support required by the engineering research institute, it is understood that the project research and development will be delayed by collecting samples of fly ash and slag. The pollution characteristics of heavy metals and dioxins and their environmental shadows were analyzed and studied, and the discharge level of the above pollutants was controlled by optimizing the sludge pretreatment system.
2. Pollution control methods will be promoted
Annual savings of over 15 million yuan in disposal costs
Residents of Haiwei Village, Ronggui Street, Shunde, do not know what "dioxin" is, nor what is printing and dyeing sludge mixing, but since October last year, residents have seen two obvious changes in Jinfang Company: One is that the company's chimneys no longer emit colored smoke, and the other is that the large trucks that regularly appeared on the village roads were no longer seen pulling sludge. "The air has also improved a lot." Several local villagers said.
A series of test data proves that the traditional textile enterprise of Jinfang Company is undergoing a quiet change. Before and after the establishment of the sludge blending and burning project in August last year, professional institutions such as the South China Environmental Science Research Institute of the Ministry of Environmental Protection, the Organic Analysis and Testing Center of the Guangzhou Institute of Geochemistry of the Chinese Academy of Sciences, and the Foshan Environmental Testing Center Station irregularly conducted investigations on Jinfang Company. The flue gas and ambient air of the company are tested. The test report shows that the flue gas generated in the process of the company's printing and dyeing sludge treatment is gradually decreasing. At present, many emission standards are lower than national and even European standards.
"After a series of research and optimization, the integrated optimization of flue gas pollution control measures has been achieved. Summarizing the corresponding technical specifications is the feature and innovation of this project." The above-mentioned person in charge of the professional center said that it is expected to establish a printing and dyeing sludge blender. The pilot project of pollution control of incineration disposal will make the pollutant emission level in flue gas reach the pollution emission standards stipulated by sludge incineration in my country, and form a set of pollution control processes and methods for mixing printing and dyeing sludge.
In the classification of the original cooperation projects in Foshan, the technical fields of the sludge blended combustion project are new energy and energy conservation and environmental protection. The frontier research has been funded by the Chinese Academy of Sciences' only innovation frontier project and the Foshan Science and Technology Bureau. It is composed of the declaration of the science and technology funds of Foshan City and the self-raised funds of Jinfang Company. At present, all the funds have been put in place, and all the work is going on as planned.
After the project is accepted in December next year, the developed pollution control method for mixing and burning of printing and dyeing sludge will be applied by cooperative enterprises and promoted by industry associations, bringing objective comprehensive economic benefits to the printing and dyeing industry. 55-60%) The direct cost of mixed burning disposal is no more than 150 yuan. "It is estimated that the annual disposal of 100,000 tons of printing and dyeing sludge in Foshan area can save more than 15 million yuan in disposal costs per year compared with entrusting an external qualified company to dispose of it. It will greatly reduce the operating and production costs of textile and garment enterprises." said the relevant person in charge of the Foshan Textile and Garment Industry Association.
