Transformation Of Low Water Discharge Dyeing And Finishing Process In Shishi Printing And Dyeing Enterprise

Learned from Shishi, the Ministry of ecology and environmental protection recently announced the completion of the cleaning and pformation task of the printing and dyeing industry in 2017. As of the end of 2017, 1416 clean and reformed printing and dyeing enterprises were reported throughout the country. Among them, 58 enterprises in Shishi, such as Wan Feng Sheng, bleaching and dyeing, and so on, had to implement the low water discharge dyeing and finishing process.

It is understood that the 58 Shishi enterprises to implement low drainage dyeing and finishing process pformation, mainly take reclaimed water, low bath ratio dyeing, steam distilled water reuse, cold pad batch, small bath than air mist dyeing, dyeing machine water reuse device, cooling water recovery, paint non water dyeing, cold pfer printing, light colored water dyeing dark color, soap wash water saving technology.

As early as 2017, Shishi introduced the printing and dyeing of stone lions.

"Transformation and upgrading work plan" to carry out special rectification actions of printing and dyeing enterprises and implement the "five major upgrading projects" to "quality high-end, green".

As a goal, we should comprehensively utilize various means such as law, economy, technology and administration to promote printing and dyeing enterprises in the centralized control area to increase investment in technological pformation. Through technological innovation, management innovation and industrial development mode innovation, the dyeing and finishing enterprises can achieve safe production, standardize operation, improve quality and increase efficiency, enhance the market competitiveness of enterprises, and promote the qualitative leap of the printing and dyeing industry.

At the policy level, Shishi encourages printing and dyeing enterprises to innovate in technology, and gradually eliminate backward printing and dyeing production equipment and technology.

Organizing and implementing the municipal key technical pformation project library, encouraging the dyeing and finishing enterprises to introduce the national industrial policy encouragement catalogue and the advanced equipment of the advanced technology catalogue recommended by the Ministry of industry and energy conservation for energy conservation and emission reduction, and accelerate the upgrading and upgrading of the old equipment.

It is necessary to eliminate the multi alkali, high temperature and time consuming pretreatment process, multi salt and multi water dyeing process, and multi color washing process.

The old equipment that is included in the "elimination standard for backward production capacity of printing and dyeing industry" and its useful life over 15 years will be phased out in batches.

Enterprises that fail to be phased out will be included in the "blacklist", do not give EIA and declare any awards or subsidies.

In accordance with the requirements of re issuing the pollutant discharge permit, the technical pformation projects of dyeing and finishing enterprises shall be examined and approved according to the regulations.

For precise management,

The printing and dyeing enterprises are also divided into four categories: ABCD.

The printing and dyeing enterprises are classified into group D and resolutely put to a stop. For printing and dyeing enterprises which have significant hidden problems in such aspects as safety production, waste gas discharge, illegal construction, fire passage blockage, on-site management, etc., they are classified into C class, implementation of production stoppage control, and printing and dyeing enterprises with no major problems in production safety, waste gas discharge, illegal building, fire passage blockage, field management and so on, which are not classified as B, and are classified into B class. Implementation of production improvement is promoted; and backward production capacity of not more than 10%, good printing and dyeing enterprises in safety production, waste gas and wastewater discharge, illegal building, fire passage blockage, on-site management and so on are classified as class A, and implementation of policy incentives and technical pformation grants are made. B is the main category of printing and dyeing enterprises. For printing and dyeing enterprises with a backward production capacity exceeding 80%, safety, environmental protection, fire protection, illegal construction and other problems, there is no hope of improvement.
