　　Petrochemical wastewater treatment process 　　(1) Physical processing method 　　Gravity separation method 　　Gravity separation method utilizes the density difference between oil and water to make oil droplets in wastewater float to the surface under the action of gravity, thereby achieving oil-water separation. Common facilities include oil separators, such as horizontal flow oil separators, inclined plate oil

　　Wastewater treatment technology in electroplating industry 　　The electroplating production process usually includes three stages: pre-treatment, electroplating, and post-treatment, each of which generates wastewater. The electroplating industry in China generally faces problems of high resource consumption and extensive business models, resulting in poor wastewater treatment efficiency. Many substandard wastewater is discharged into rivers, seriously polluting the
