Technological innovation in coke wastewater treatment and green transformation go hand in hand

Industrial drainage of coke, as an inevitable contaminated in the process of producing the coke industry, is characterized by a complex and high toxic composition, which is a serious challenge to the environment and ecosystems. However, with increased environmental awareness and technology development, the field of cooking drainage water treatment is witnessing a deep shift, as technical innovations and green shifts go side by side, pumping a new vitality into sustainable development of coke manufacturing.

First: The properties of cooking coal and the difficulties of treating it

Cooking cooking water is mainly created from dry carbon operations for charcoal at high temperatures, gas purification, and chemical products, as they contain high concentrations of nitrogenine ammonia, phenols, oils and other harmful substances, in addition to significant fluctuations in water quality and the difficulty of treating them. These pollutants are not only seriously contaminating the environment, but also a potential threat to the aquatic ecosystem. Therefore, cooking water drainage treatment has become a major issue that must face coke industry.

Second: technological innovation and upgrading

In recent years, with the advancement of science and technology, coke wastewater treatment technologies have made significant progress. Technologies such as chemical precipitation, adsorption, advanced oxidation, and reverse osmosis have been widely used in advanced coke wastewater treatment.

Chemical sedimentation adds coagulants to cause suspended and colloidal materials in wastewater to clump and settle, effectively reducing water turbidity and suspended matter content. Adsorption, on the other hand, relies on porous adsorbents such as activated carbon to absorb specific pollutants from wastewater for purification.

As for advanced oxidation techniques, such as Fenton oxidation or ozone, they rely on the generation of free radicals with a high oxidation capacity to disintegrate organic pollutants, and are characterized by high efficiency and great reaction speed. In particular, ozone technology, which not only removes pollutants such as phenols and cyanide, but also contributes to reducing chemical oxygen demand (COD) and biochemical oxygen demand (BOD), in addition to its color and odor removal and sterilization properties.

Reverse osmosis is a highly efficient membrane separation technology. A specific pressure is applied to allow water molecules to pass through the reverse osmosis membrane, while dissolved salts and impurities are retained on the other side of the membrane, achieving effective purification of wastewater. However, this technology has some limitations, such as the difficulty of treating concentrated water and membrane fouling issues, which require further improvement and development in practical applications.

Third: Green transformation to promote sustainable development

In the process of cooking cooking water, the green transformation has become an important direction to enhance the sustainable development of the industry. On the one hand, it is possible to improve production processes and reduce the amount of wastewater and the concentration of pollutants, to reduce the difficulty of treatment and reduce its costs from the source. On the other hand, ways to reuse treated wastewater are explored, such as returning it to the production process or using it as an alternative source of other industrial water, which achieves the concept of "converting waste into resources".

In addition, enhancing the formulation and application of environmental laws, and pushing companies to adopt more efficient and environmentally friendly drainage treatment techniques, is also an important way to support green transformation. The increase in investments in research and development in the field of coal drainage techniques, policy support, and encourage companies to innovate and raise the level of treatment, are all steps that enhance green development for the coke industry.
