Bobbin type device for degrading triclocarban (TCC) in water by virtue of dielectric barrier discharge coordinated with activated carbon fiber and method of device

Abstract

The invention discloses a bobbin type device for degrading triclocarban (TCC) in water by virtue of dielectric barrier discharge coordinated with activated carbon fiber and a method of the device. The device comprises a cylindrical reactor, a water distributing groove communicated on the upper part of the cylindrical reactor, a circulating buffer container and a rod-like high voltage electrode and a grounding electrode which are respectively connected with the positive and negative electrodes of an alternating current high voltage power supply, wherein the rod-like high voltage electrode is arranged in the cylindrical reactor while the grounding electrode covers the outer wall of the cylindrical reactor; activated carbon fiber layers are fixedly arranged on the inner walls of the cylindrical reactor; porous baffle plates are arranged on the surfaces of the activated carbon fiber layers; the circulating buffer container is respectively communicated with a waste water inlet formed on the side wall of the water distributing groove and a waste water outlet formed in the bottom of the cylindrical reactor to form a waste water circulating pipeline. The device is simple in design and low in equipment investment, the degrading efficiency can be improved by fully utilizing ozone generated by catalysis of the activated carbon fiber, and moreover, regeneration of the activated carbon fiber is realized, so that the device can be applied to treating organic waste water which is difficult to be biochemically degraded.
