Applicable to the "Classification of National Economic Industries" (GB/T4754-2011), the industry code and category name are C171 cotton textile and printing and dyeing finishing, C172 wool textile and dyeing and finishing, C173 hemp textile and dyeing and finishing, C174 Silk spinning and printing and dyeing finishing, C175 chemical fiber weaving and printing and dyeing finishing industry.
Including textile enterprises with printing and dyeing/dyeing and finishing processes.

Vigorously promote the implementation of cleaner production by textile printing and dyeing enterprises.
Promote the use of environmentally friendly dyes and dyeing auxiliaries with low toxicity and low volatility.
Key enterprises in the cotton textile and printing and dyeing finishing industries should use medium-temperature and medium-pressure steam shaping instead of heat-conducting oil furnace shaping, and chemical fiber printing and dyeing enterprises are encouraged to develop and apply post-finishing technology that uses steam or natural gas as the heat source for heat shaping.

Strengthen the emission control of waste gas from setting machine, printing waste gas and waste water treatment station waste gas.
The shaping (stenter drying) equipment should be equipped with exhaust gas collection and purification and waste heat recovery devices to ensure that there is no obvious shaping machine smoke and pungent odors in the workshop.
Use mechanical purification, spray washing, electrostatic dust removal, incineration and other processes or optimized combinations to purify organic waste gas.
High-temperature waste gas should be recycled through the heat recovery system.
The waste gas of the stereotypes machine that adopts electrostatic treatment should adopt three or four electric field horizontal types.
Electrostatic precipitators.
Companies equipped with a printing section must adopt a closed operation to avoid solvent volatilization, and install a gas hood at the printing workbench.
After the exhaust gas is collected and purified by adsorption and recovery, the purification efficiency must not be less than 90%.
The treatment structure of the sewage treatment station shall be covered and sealed, and waste gas collection and treatment facilities shall be set up, and the waste gas shall be discharged up to the standard after collection and treatment.

Plastic manufacturing and plastic products industry

Applicable to the industry code and category name in "Classification of National Economic Industries" (GB/T4754-2011): C2651 primary form plastic and synthetic resin manufacturing, C292 plastic products industry.
Focus on controlling the manufacturing of primary form plastics and synthetic resins, as well as the manufacturing of solvent-based adhesive tapes, artificial leather, and synthetic leather.

Vigorously promote cleaner production.
Antioxidants, plasticizers, foaming agents and other organic additives used in the production process should be sealed and stored.
All production processes involving VOCs emissions such as hot melt, injection molding, and drying should be carried out in a closed workshop as much as possible, and must be installed There are waste gas collection systems and purification treatment facilities that meet environmental protection requirements.

Strengthen the treatment of VOCs waste gas.
According to the characteristics of the VOCs emitted by the volatilization of organic solvents and the pyrolysis of polymer compounds during the production of various types of products such as polyethylene, polypropylene, polyvinyl chloride, polystyrene, phenolic, amino plastics, etc.
, select appropriate recycling and purification treatment technologies.
The total purification efficiency of exhaust gas should reach more than 90%.
Each production process unit such as batching, mixing, granulation, extrusion, calendering, foaming, etc.
should be equipped with waste gas collection and purification treatment devices; the coating production process of tape manufacturing should be equipped with organic waste gas recovery treatment devices.
Ingredients, feeding, and mixing tail gas should be treated with high-efficiency dust removal devices such as bag dust removal.
The tail gas of filtration, calendering, and bonding can be recycled and treated by electrostatic demisters.
Foaming waste gas should be treated by high-temperature incineration technology.
