Research Progress on Treatment Technology of Automotive Coating Wastewater
According to the incomplete statistics of relevant departments,from January to August 2023,the painting wastewater generated by China's automobile industry is about 301.2×104 m3,and by 2030,the output of automobile painting wastewater will reach 720×104 m3.Because the automobile coating wastewater contains toxic and harmful substances,if it is not properly treated,it will pollute the ecological environment,groundwater,soil and so on.Because of its variable water quality and quantity characteristics,the treatment process of automobile coating wastewater has always been the focus of research scholars and automobile manufacturers.This paper mainly reviews the treatment technology of automobile coating wastewater applied in engineering field at home and abroad,and expounds the advantages and disadvantages of its process characteristics,operation and maintenance,energy saving and consumption reduction,investment cost,etc.The future trend of automobile coating wastewater treatment will be to create a combination process technology route tailored to different automobile coating processes,but the relationship between cost reduction and efficiency,energy saving and consumption reduction,environment and economy should be balanced.
