Integrated treatment method of high-concentration liquid crystal waste water

The invention belongs to the technical field of chemical production waste water treatment and relates to an integrated treatment method of high-concentration liquid crystal waste water. The method comprises the steps of adjusting the high-concentration liquid crystal waste water, allowing effluent to enter a Fenton reactor for reaction, adjusting a pH (potential of hydrogen) value of a reacted solution to 7, keeping the solution static, taking supernate into an SBR (sequencing batch reactor) for aeration reaction, after natural settling, discharging the supernate into a TiO2/active carbon photocatalytic reactor, switching on an ultraviolet light source, activating a photocatalytic reaction, and allowing iron sludge generated by the Fenton reactor and little sludge generated in the SBR to enter a microwave degradation furnace for drying and degradation to achieve integrated treatment of the high-concentration liquid crystal waste water. The method is simple and novel in technology, convenient to operate, low i
