Chlorophenol wastewater belongs to highly toxic industrial wastewater, which can cause serious harm to the environment and human health if not treated effectively. The current treatment methods for chlorophenol wastewater are divided into physical, chemical, and biological methods. The physical adsorption experiment found that the monodisperse magnetic nano-column was prepared by the solvothermal method, which could remove 91.5% of pentachlorophenol within 30 mins. More than 90% of chlorophenol can be extracted using an ionic liquid as an extractant. When the chlorophenol reaches 15 g/L, the extraction rate only slightly decreases. CaO and SiO2 can achieve 99.0% 2,4,6-trichlorophenol in 6 hours as ball milling materials by physical and chemical methods. The electrochemical reduction test found that using Pd/Py SDBS/Ti as the cathode, 2-chlorophenol, 4-chlorophenol, and 3-chlorophenol could be reduced and dechlorinated, in which 100 mg/L of 2-chlorophenol could be completely degraded within 60 minutes. The biochemical index BOD5/COD of wastewater is less than 0.3 if the biological treatment technology based on co-metabolism is adopted to realize the chlorophenol treatment. In treating chlorophenol wastewater, the application scenario should be fully considered to achieve the best treatment effect of chlorophenol wastewater.
