The industrial steel roller needs to strictly abide by environmental protection regulations during the production process, pay attention to pollution prevention and control as well as resource recycling, in order to reduce the impact on the environment. The following are specific environmental protection precautions:
1. Wastewater treatment and recycling
Classification collection and treatment: Etching wastewater contains heavy metal ions (such as copper, nickel, etc.), acidic and alkaline substances, and organic matter. It needs to be collected by composition classification and treated by technologies such as chemical precipitation, ion exchange, and membrane separation to ensure compliance with discharge standards.
Recycling and reuse: Through technologies such as reverse osmosis and evaporation concentration, water resources and valuable metals in wastewater are recovered, reducing the consumption of fresh water and the discharge of waste liquid.
2. Waste gas treatment
Acid mist and organic waste gas control: The acidic gases (such as hydrogen chloride and sulfuric acid mist) and organic waste gases (such as volatile organic compounds, VOCs) generated during the etching process need to be treated through acid mist purification towers, activated carbon adsorption, catalytic combustion and other devices to reduce the emission concentration.
Local exhaust and closed operation: Local exhaust systems are installed at key workstations such as etching tanks and developing tanks to reduce the escape of waste gas.
3. Solid waste management
Standardized disposal of hazardous waste: Hazardous wastes such as spent etching solution, spent filter elements, and spent activated carbon must be entrusted to qualified units for treatment, and the transfer manifests system must be strictly implemented.
General solid waste resource utilization: Metal scraps, waste packaging materials and other general solid wastes should be classified and recycled to achieve resource reuse.
4. Noise and Vibration Control
Equipment noise reduction: Select low-noise equipment and install silencers and shock-absorbing pads on high-noise equipment such as fans and pumps to reduce noise transmission.
Rational layout: Place high-noise equipment in independent workshops or basements to minimize the impact on the surrounding environment.
5. Chemical Management
Safe storage and usage: Chemicals such as etching solution and developer solution should be stored in dedicated warehouses, equipped with leak-proof pallets and ventilation facilities, and strictly managed by two people and double locks.
Substitution and reduction: Prioritize the use of low-toxicity and low-volatility chemicals, and adopt clean production processes such as micro-etching and cyanide-free electroplating to reduce the generation of pollutants.
6. Environmental Monitoring and Emergency Management
Online monitoring and regular testing: Install online monitoring equipment for wastewater and waste gas, and regularly entrust third-party testing institutions to conduct full-index testing to ensure that pollutants are stably discharged up to standard.
Emergency response plans and drills: Develop emergency response plans for sudden environmental incidents, equip with emergency supplies, and organize regular drills to enhance response capabilities.
7. Energy Conservation and comprehensive utilization of resources
Energy management: Adopt high-efficiency and energy-saving equipment, optimize production processes, and reduce energy consumption such as electricity and steam.
Water resource recycling: Build a reclaimed water reuse system to utilize the treated wastewater for cooling, cleaning and other processes, thereby enhancing the utilization rate of water resources.
8. Clean production and Green Supply Chain
Clean production audit: Regularly conduct clean production audits to identify and improve high energy-consuming and high-pollution links, and continuously reduce environmental load.
Green procurement: Prioritize the selection of environmentally friendly raw materials and suppliers to promote the greening of the industrial chain.
9. Employee training and environmental awareness
Operation specification training: Strengthen the training of employees on environmental protection regulations and operation procedures to ensure standardized operations and reduce man-made pollution.
Environmental protection culture construction: Through publicity and education as well as incentive mechanisms, enhance the environmental awareness of all staff and create a green production atmosphere.
10. Compliance and Information Disclosure
Information disclosure: Proactively disclose environmental information of enterprises, accept social supervision, and enhance the credibility of enterprises.
Summary: industrial steel roller needs to start from multiple aspects such as wastewater, waste gas, solid waste and noise, establish a full-process environmental protection management system, adopt advanced technologies and management methods, achieve the reduction, resource utilization and harmless treatment of pollutants, and promote the green and sustainable development of the enterprise.
