Application of VOCs treatment technology in direct coal liquefaction wastewater treatment process
Direct coal liquefaction is the process of converting raw coal,hydrogen gas,supplementary sulfur,and catalyst into liquid fuel through hydrocracking under high temperature and pressure,with an annual production of 1 million tons of oil.In this production process,the amount of wastewater generated is 80-100t/h,and the wastewater produced has characteristics such as high pollutant concentration,deep chromaticity,large water quality fluctuations,and high difficulty in biodegradation.During the collection,storage,treatment and disposal of wastewater,a large amount of VOCs may escape,which can easily cause environmental pollution incidents.By selecting advanced and reliable waste gas treatment technologies,the biological toxicity of waste gas can be effectively reduced,and the production and living environment of employees can be improved,which is beneficial for the overall image enhancement of enterprises and regions.
