Research of advanced treatment technologies for chlorophenol wastewater

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