The most scientific and practical metal processing waste liquid emission reduction measures!
With the rapid development of industrialization, the metal processing industry has not only promoted social progress, but also brought environmental problems such as waste liquid discharge. Metal Working Fluid is a lot of heavy metals and harmful chemicals. If it is discharged directly without treatment, it will pose a serious threat to the ecological environment and human health. Therefore, it is particularly urgent to take scientific and practical measures to reduce waste liquid emission.
First, optimize the process flow to reduce the generation of waste liquid
In the process of metal processing, raw materials with low pollutant content should be preferred to reduce the generation of waste liquid from the source. At the same time, strengthen the process transformation, the use of closed operation, reduce the use of water, reduce the discharge of pollutants. In addition, through technology upgrading and equipment updating, used Corrosion Inhibitor, production efficiency is improved and the amount of waste liquid generated is reduced.
Second, the establishment of waste liquid recycling system
The key to achieve the reduction and treatment of waste liquid is to establish an efficient waste liquid recycling system. By adopting an efficient water recycling system, the waste liquid is recovered, treated and reused, reducing the use of fresh water, reducing production costs and achieving emission reduction.
Physicochemical treatment technology
For heavy metal ions and suspended substances in metal processing waste liquid, physical and chemical treatment technology can be used for further treatment. For example, the use of precipitation, filtration, adsorption and other methods to reduce the concentration of pollutants in waste liquid, so that it can meet the relevant national emission standards. At the same time, combined with appropriate chemical agents, neutralization, REDOX treatment,Metal Working Fluid Additive, etc., to improve the treatment effect of waste liquid.
4. Biological treatment technology
Biological treatment technology is also one of the effective means to treat metal processing waste liquid. Through biological treatment methods such as activated sludge process, microorganisms are used to degrade harmful substances such as organic matter and heavy metals and convert them into harmless substances to further reduce the toxicity of waste liquid.
Fifth, strengthen monitoring and management
The establishment of wastewater discharge monitoring system is the key to ensure the effective implementation of emission reduction measures. Through the combination of regular monitoring, online monitoring and temporary monitoring, the real-time grasp of waste liquid discharge, and ensure that waste liquid discharge meets the relevant national standards. At the same time, strengthen the operation and management of waste liquid treatment facilities, regular maintenance and overhaul to ensure the stable operation and efficient treatment of facilities.
6. Promote technological innovation and research and development
With the continuous progress of science and technology, new waste liquid treatment technologies continue to emerge. Metal processing enterprises should pay attention to the industry dynamics, actively introduce and apply new technologies and new processes, and improve the efficiency and effect of waste liquid treatment. At the same time, strengthen cooperation with scientific research institutions, universities and other units to jointly research and develop waste liquid treatment technology applicable to the metal processing industry, and promote the green and sustainable development of the industry.
To sum up, the emission reduction of metal processing waste liquid is a systematic project, which needs to start from many aspects such as source control, process optimization and end treatment. By optimizing the process flow, establishing the waste liquid recycling system, adopting physicochemical and biological treatment technology, strengthening monitoring and management, and promoting technological innovation and research and development, the emission of metal processing waste liquid can be effectively reduced, and the ecological environment and human health can be protected.
Looking to the future, with the increasing awareness of environmental protection and the continuous improvement of environmental regulations, the metal processing industry will pay more attention to the waste liquid emission reduction work. We believe that with the joint efforts of the whole society, we will be able to achieve the green and sustainable development of the metal processing industry.
