In the face of increasingly severe environmental situation, Lanzhou Petrochemical to increase technological transformation, has invested nearly 300 million yuan for the construction of wastewater treatment facilities and wastewater treatment of new technologies, the introduction of new technologies.
Before the introduction of the new environmental protection law, Lanzhou Petrochemical will upgrade the chemical wastewater upgrading project as a key emission reduction project, the use of domestic advanced "air flotation + ozone contact oxidation + aeration biofilter" technology, the chemical wastewater treatment plant renovation. After the completion of the transformation of the device biochemical system COD, chromaticity and other removal efficiency significantly improved, the treated effluent is better than the new environmental standards indicators required. Realize the economic and environmental protection double benefits.
Lanzhou Petrochemical actively carry out waste gas treatment, in 2013, 2017 has been built and put into use chemical sewage waste gas purification device and the largest refinery sewage waste gas purification device in Northwest China, the concentration of soluble volatile gases discharged in the production is far below the standard.
Huang Xuyong, head of the production technology section of the sewage treatment plant, said, "Adsorption condensation, ozone oxidation, biological oxidation and other new technologies and processes applied to environmental protection and governance, the main device wastewater, waste gas can achieve stable standards."
At present, Lanzhou Petrochemical is catalyst wastewater treatment, refinery wastewater treatment device reverse osmosis thick water transformation, refinery wastewater and catalyst wastewater air supply system optimization projects such as technical research and scientific research and testing, in order to further enhance the level of emission reduction, to promote the green and clean production, to contribute to the "Lanzhou blue".
