NOVELTY - Method for removing medicine and personal care product in wastewater, involves (i) treating wastewater by a 1-5 mm fine grid decontamination machine, coagulating and settling to obtain wastewater containing medicine and personal care product, (ii) passing the pretreatment wastewater into iron-carbon micro-electrolysis reactor for 0.5-1 hour, and passing iron-carbon micro-electrolysis effluent into electric Fenton reaction cell, (iii) subjecting effluent of the electric Fenton reactor to regulating tank, and subjecting the photocatalytic nanofiltration section at an effluent flow rate of 100 l/hour, and directly connecting effluent to electric adsorption system, where the photocatalytic nanofiltration section consists of the photocatalytic section and the nanofiltration section, and (iv) processing the effluent from the nanofiltration filter for desalination through an electro-absorption device, and reusing after the detection reaches the standard. USE - The method is useful for removing medicine and personal care product in wastewater. ADVANTAGE - The method reduces the load of the subsequent sections, combines iron-carbon micro-electrolysis-electric Fenton treatment to make the ferrous ions generated during the iron-carbon micro-electrolysis treatment directly used as an electric Fenton catalyst, reduces the treatment cost, shortens the treatment time, thoroughly mineralizes the pharmaceuticals and personal care products (PPCPs) in the wastewater through photocatalytic treatment, removes trace organic pollutants and some inorganic salts remaining in the water to improve water quality, improves the treatment efficiency, uses the electric adsorption system for desalination, and ensures excellent effluent quality than the GB/T19923-2005 industrial water quality standard.
