A device and a method for removing degradation-resistant organic matters in a membrane filtration concentrate liquid

The invention discloses a device and a method for removing degradation-resistant organic matters in a membrane filtration concentrate liquid. The method adopts a coagulation-high-grade oxidation-biochemical treatment combined process. The method includes a step of subjecting the membrane filtration concentrate liquid to coagulation materialization pretreatment with Fe being adopted as a coagulant and polyacrylamide (PAM) being adopted as a coagulant aid, namely a step of fully stirring, mixing, reacting for a certain period of time, allowing the mixture to stand, settling, separating to obtain a supernatant liquid L1; a step of high-grade oxidation, namely a step of subjecting the supernatant liquid L1 to high-grade oxidation by utilizing a UV/Fe/O3 combined process, and separating to obtain a supernatant liquid L2; a step of biochemical treatment, namely a step of feeding the supernatant liquid L2 into a biochemical treatment unit, treating further and discharging.
